Introducing Our ESG Committee: Embracing Sustainability and Community

Written by Ellis Fowler on . Posted in Company, News. No Comments on Introducing Our ESG Committee: Embracing Sustainability and Community

Power Adhesives are thrilled to announce the launch of our brand-new Environmental, Social, and Governance (ESG) Committee. This initiative, a huge step-forward in the business’ history, reflects our commitment to sustainable practices, ethical governance, and social responsibility. This blog will help you to understand what our ESG Committee is all about and how it can benefit both our business, and the local community.

What is the ESG Committee?

The ESG Committee is a specialised group within our organisation that’s dedicated to integrating ESG principles into our business strategies and operations. The committee primarily focuses on:

  • Environmental Stewardship: The concept of developing and implementing practices that reduce our environmental footprint. This ranges from energy efficiency through to waste reduction, and sustainable sourcing – all initiatives aimed at protecting our planet.
  • Social Responsibility: We want our business practices to contribute to social well-being. That means creating a diverse and inclusive workplace, supporting community development projects, and maintaining high labour standards.
  • Governance Excellence: We hold ourselves to the highest standards of corporate governance. Transparency, ethical business practices, and accountability to stakeholders are at the core of what we do.

How Does the ESG Committee Benefit Our Business?

  • Company Responsibility: By embracing ESG principles, we gain a better understanding of how we operate, both internally and externally, allowing us to take more responsibility for our sustainability and ethical practices.
  • Risk Management: ESG initiatives improve our recognition of potential risks related to environmental impact, social issues, and governance. Taking a proactive approach protects not only our business and stakeholders, but the wider community too.
  • Operational Efficiency: Implementing sustainable practices helps to identify prospective improvements to our operations. For example, energy-saving measures can cut costs, and responsible supply chain management can streamline our operations.
  • Employee Engagement: A strong ESG commitment can make our employees happier; people want to work for companies that align with their values and make a positive impact on society.

How Does the ESG Committee Benefit the Community?

  • Environmental Protection: We hope that our efforts to minimise our environmental impact will, in turn, encourage other companies in a similar position to make comparable adjustments to their processes. Working together, companies can have a positive effect on the community’s health and sustainability.
  • Social Inclusion: We’re all about promoting diversity, equality, and inclusion within our company and beyond. By supporting community initiatives and creating opportunities for underrepresented groups, we hope to contribute to a fairer society.
  • Economic Growth: The scope of our ESG initiatives often cover community development projects that can stimulate local economic growth. We are exploring investments in local businesses, job creation, and support for educational programs.
  • Transparency and Trust: We believe in maintaining high standards of governance and transparency to build trust with our community.

Our ESG Committee is the first big step we’re taking towards becoming a community-friendly business. By embedding ESG principles into our core operations, we strive for sustainable growth while benefiting the communities we serve. We’re excited to share our progress with you on this journey and hope we encourage other businesses explore how they can create a better local environment for everyone.

Demystifying Hot Melt Adhesives: A Comprehensive Guide

Written by Ellis Fowler on . Posted in Technical Information. No Comments on Demystifying Hot Melt Adhesives: A Comprehensive Guide

Contrary to what many believe, hot melt adhesives and hot melt technology have progressed far beyond the crafting and DIY industries. For new or inexperienced users of hot melts, it can be confusing trying to work out all the variables involved, and how to get the best from these adhesives.

In this blog, we’ll explore what hot melt adhesives are, what to consider before using them, and some tips to get the most out of the technology.

What is a hot melt adhesive?

A hot melt adhesive, or hot melt glue, is a type of thermoplastic adhesive that’s applied in a molten state and solidifies upon cooling to form a strong bond between two substrates.

They’re typically made up of a base polymer to which other raw materials are added. This polymer acts as the framework on which the adhesive and its properties are based. Other raw materials that may be part of the final formulation include tackifiers in the form of resins, waxes that adjust variables such as surface tack and viscosity, and additives to give the finished adhesive more stability.

Unlike many other forms of adhesive, hot melt adhesives are 100% solid materials with no solvents. At room temperature, they are safe to handle and, in many cases, have a near-unlimited shelf life. They’re also able to be remelted and set several times without compromising their adhesive properties.

Hot melt adhesives are commonly used in the packaging, woodworking, product assembly, and crafting industries, but they are also prevalent in the automotive, construction, and electrical sectors.

What factors affect hot melt choice?

Much like other adhesive systems, hot melts are not universally applicable and aren’t a ‘one size fits all’ solution. Although many formulations are classified as general purpose, there are specialised grades tailored to distinct applications and substrates.

These specialisations range from different viscosity levels for better gap-filling or tighter joins, to extended or shortened working times tailored to how quickly the bond needs to be formed.

For these reasons, it’s important to understand the following factors:

  • What materials are you bonding? How do they react to high temperatures?
  • How long after application do you need the adhesive to stay “tacky”?
  • Is it preferable to have a thicker or thinner adhesive bead?
  • Do you require an instant set when the materials are brought together, or do you need time for adjustments?
  • Will the final bond be under any extreme temperatures? Both high and low.
  • Will the final bond be visible, or does it need to blend with the materials to which it’s bonding?
  • Does the final bond need to have some flexibility?

If you can answer all of the above questions, you’ll be able to specifically search for your perfect hot melt adhesive.

Hot melt or Low melt?

Closely linked to factors that affect your hot melt choice, there are a range of hot melt adhesives specifically formulated for use with heat-sensitive substrates.

Regular hot melts are designed to run at temperatures exceeding 160°C (320°F). At these temperatures, sensitive materials such as plastic films, expanded polystyrene and many foams will melt or burn. For these substrates, a hot melt which functions at a lower temperature is required.

This is where low melt adhesives excel. These are specially formulated to maintain the same adhesive properties as their hot melt counterparts but are dispensed at much lower temperatures (120°C to 130°C or 250°F to 265°F).

So, before you look at buying a certain glue gun or hot melt adhesive, you should consider what materials you’re bonding, and whether you will need hot or low melt systems.

For a better understanding of hot melt adhesive grades and their chemistry, check out our Tecbond adhesive guide, which outlines our most popular hot melt adhesives and their specifications.

Application Method

Once you’ve decided what kind of hot melt you require, you can then join this choice with the most suitable application method.

The most common application method is a hot melt glue gun or glue applicator. As well as being the easiest to use, glue applicators are available in a variety of different models to best suit the application. These variations include:

  • Adhesive size (12 and 15mm sticks and 43mm slugs)
  • Melting/output temperature
  • Melt rate and output (linked to adhesive size)
  • Corded or cordless
  • Application form (bead or spray)

The biggest benefits of hot melt glue guns are their speed and precise control. With warm-up times of around five minutes or less, and the ability to control how much hot melt is dispensed with each pull, they’re the go-to choice for most users and industries.

The other common application method is bulk machinery. This application method is more common in fast-paced industrial environments where processes are automated, such as packaging and assembly lines. Bulk machinery tends to have much higher output and can operate all day with minimal to no downtime.

These machines work by having a tank filled with molten hot melt that is kept at a constant temperature. This molten hot melt is then dispensed automatically when required. The drawback to these machines is their high price and lack of portability.

Before choosing an application method, it’s important to understand if the hot melt you wish to use is compatible and the best fit. Certain hot melt formulations will work better with tools that run at a higher temperature, while others are available in formats that better suit bulk dispensers than glue guns. Always refer to technical data sheets for both the hot melt adhesive and applicator before making a purchase.

If you’re using a Tecbond formulation and Tec glue applicator, you can refer to our Tec glue gun guide, which details each applicator.

Tips for using hot melt adhesives

As with any adhesive technology, some best practices will ensure you get the most out of your hot melts.

  • Ensure your hot melt stick or slug is clean and dry before inserting it into your applicator – Moisture can not only potentially damage the internal components but also affect the adhesive qualities.
  • Ensure the hot melt isn’t misshapen – This can cause blockages in the applicator, leading to adhesive meltback.
  • Don’t leave glue guns on and idle for extended periods – Despite not being in use, the internal heating system will continue to melt adhesive currently in the glue chamber. This can lead to nozzle leakage or adhesive meltback.
  • Do not exceed recommended application temperatures – Running adhesives above recommended temperatures can cause burning or charring, as well as changing properties such as viscosity and open time.
  • Use the correct amount of adhesive – Don’t be tempted to over-apply adhesive. Not only will larger amounts of adhesive increase open time, but it may negatively affect the substrate you are attempting to bond (saturating a very porous substrate for example).

Conclusion

In conclusion, hot melt adhesives offer a versatile and efficient solution for bonding different materials across a wide range of industries. As we’ve explored in this comprehensive guide, understanding the composition, application methods, and factors influencing the choice between hot melt and low melt adhesives is crucial for achieving optimal results in your projects.

Colours, Kits and Bags

Written by Ellis Fowler on . Posted in Product Updates. No Comments on Colours, Kits and Bags

Outside of the bigger tool announcements this quarter, we’ve made other changes to popular products in our portfolio.

We started by upgrading our old plastic carry cases to a new, more sustainable fabric bag. Not only do they reduce the amount of plastic within our product range, but these new bags have fully customisable inserts to fit any of our applicators and accessories.

Alongside the case update, we updated our Knottec multipack to include some black sticks instead of larch. This pack now better reflects our most popular colours, not only providing new users with a range of colours to try but also giving repeat purchasers the most flexibility with colour choices in one pack.

Lastly, our cordless 12mm and 15mm tools were given a facelift with some new red handles, new labels, and on the Tec 808 specifically, a new on/off switch in a more convenient position for the tool size.

Selecting the right precast concrete grade for you

Written by Ellis Fowler on . Posted in Construction. No Comments on Selecting the right precast concrete grade for you

Casttec adhesives are a simple and cost-effective way to bond architectural and structural accessories to precast concrete forms. They present a faster alternative to traditional insert bonding methods such as welding, bolting, and taping.

Casttec adhesives are used globally, and need to perform across a range of temperatures and conditions. With four grades to choose from, each formulation in the casttec range is designed to complement the conditions of its use.

Casttec 42 is a versatile, all-purpose precast adhesive designed to offer the best all-around performance of all the casttec grades. Along with a fast delivery rate and an extended open time for accurate assembly, the adhesive crystalises after 24 hours, eventually becoming very brittle. This allows for easy cleanup after the concrete has set inside the mould. For more information on casttec 42, check out our recent AOM blog post.

All other casttec adhesives are based on this original grade but have been formulated to offer different benefits and characteristics, depending on the environment they’re used in or the processes they have to go through.

Designed to be used in colder environments or during the winter months, Casttec 45 offers users a longer recrystallisation period. This ensures the adhesive keeps its tack and doesn’t set before the necessary processes are complete. Furthermore, the adhesive’s brittle point is around 0 °C, meaning it will retain its strong bonding capabilities at lower temperatures.

Conversely, casttec 47 has been formulated for use in warmer environments and summer months. Its chemical composition means it can be applied, allowed to set, and removed at temperatures close to 40°C, without compromising the qualities of the adhesive. Regular precast adhesives will take much longer to set and crystalise in warmer conditions due to the increased heat they’re subjected to.

Alongside these grades for different temperatures, the casttec range also features two additional adhesives designed for longer-lasting bonds and easy removal, respectively.

Casttec 43 has been designed to have a much tougher overall bond than the other adhesives, even after crystallisation, which is a necessity if the form is used for several pour cycles. Although this grade is harder to clean up after use, its stronger bond decreases the work required in between pour cycles. This formulation also has double the open time of any other casttec adhesive, allowing much larger and more complex inserts to be glued before being bonded to the necessary substrate.

For bonding applications involving fiberglass, resin-coated, and epoxy-coated surfaces, we recommend using casttec 40. Compared to other adhesives in the casttec range, casttec 40 offers users an easier clean-up with minimal chance of damaging the bonded substrates. Once the adhesive crystalises, it becomes even more brittle than the standard adhesive, allowing easy removal without the need for excessive scraping.

Despite their differing properties, all casttec adhesives are compatible with the tec range of 43mm bead and spray applicators. These applicators have been designed and produced in tandem with the adhesives, ensuring both the adhesive and tool deliver optimal results and the best possible performance for the user.

When applied with the unique spray applicators, casttec adhesives are safe to use with heat-sensitive substrates such as foam or expanded polystyrene. The thin filament extruded by the gun cools quickly while maintaining high levels of tack, ensuring no burning or melting occurs.

Casttec adhesives are also non-toxic, with no harmful solvents or VOCs given off during the application process, making them safer to work with and contributing to a cleaner environment.

43mm hot melt adhesives: Why should you use them?

Written by Ellis Fowler on . Posted in Applications. No Comments on 43mm hot melt adhesives: Why should you use them?

For over 40 years, Power Adhesives has been producing hot melt adhesive formulations in 43mm diameter slugs.

But why would you need 43mm slugs? What applications are they most beneficial for? And why should you choose to use 43mm adhesives over the traditional 12mm sticks?

Output

Looking to increase overall adhesive output? Then opt for a larger adhesive diameter! Certain industries and applications require a greater amount of adhesive per trigger pull, and 12mm glue guns can only provide a certain amount of adhesive, no matter how efficient the tool is.

Changing to 43mm hot melts allows the use of a bigger glue gun with more powerful heating systems and more efficient technology. This, in turn, results in a faster melt rate and increased output per kilogram.

For example, the highest output 12mm tec glue gun dispenses around 2.5kg (5.5 lbs) of adhesive per hour. Contrast that with the entry-level 43mm tec glue gun, which dispenses around 3kg (6.5 lbs) per hour, with that output increasing with each more powerful tool up to the tec 7300, which has an output of 5.25kg (11.25 lbs) per hour.

Thanks to the impressive output 43mm adhesives provide, hot melts are now commonly used in both the foundry and precast industries, both demanding applications that require constant adhesive application in large quantities.

Spraying ability

It’s not just output that’s affected, as changing to 43mm adhesives opens up the range of tec spray applicators too. These spray tools not only increase adhesive coverage, but also enable adhesive formulations to be used on heat-sensitive substrates that can burn or melt when used with a regular hot melt glue gun.

Widely used in the product assembly and construction industries, formulations such as spraytec 410 and 420 aren’t available in 12mm sticks as their intended application requires a higher volume of adhesive to speed up the overall bonding process.

New possible formulations

Depending on the raw material makeup of the adhesive, many hot melts won’t work as 12mm sticks as they won’t hold together in smaller formats. Many grades, like tecbond 263, are only available in 43mm slugs, as their chemical makeup means the final formulation is quite soft and malleable.

Attempting to produce a 12mm stick with a formulation that is too “soft” may potentially damage the equipment it’s used with. Some of these issues include stick warping, stick breakages, and adhesive meltback, which in turn affect the performance of the extruded adhesive and how it bonds.

43mm slugs counter this issue, as the greater amount of glue results in an overall stronger slug. Think of it like this: you’re able to rip a piece of paper but cannot rip an entire catalogue; the same principle applies to the hot melt.

Conclusion

43mm hot melt slugs are the ideal adhesives for high-powered industries that need a constant supply of adhesive or need access to formulations that aren’t available in traditional 12mm sticks.

Since we started producing 43mm adhesives over 40 years ago, we have been constantly developing new formulations and updating glue gun technology to make these adhesives perform at their highest potential.

Created as part of a complete hot melt system, our 43mm adhesives work best with our range of 3000, 6000, and 7000 series of applicators. Tools such as the 3400 come with a range of temperature modules, so you can dispense glue at the exact temperature needed for the application.

If you’re looking to switch to 43mm adhesives, speak to one of our sales team about switching over and discovering the benefits for yourself.
