The two types of bonding – Physical and chemical

When working with hot melts, there are many specialised grades that focus on specific bonding requirements or are formulated to meet an industry standard. Tecbond 213, however, is the best-selling general-purpose grade thanks to its ability to provide solid, long-lasting bonds on a wide variety of materials while also being extremely cost-effective.

Polyamide adhesives are a unique subset of hot melt adhesives, providing distinct properties that set them apart from other forms of hot melt. Unlike conventional EVA or metallocene-based hot melts, polyamides offer a combination of tensile strength, high-temperature resistance, and strong adhesion to a wide range of substrates. They are used in a wider variety of applications from automotive to textiles, thanks to their versatility and efficiency.

A leading polyamide adhesive in the tecbond range, tecbond 7785 is the go-to grade for bonding substrates that regularly experience high temperatures and frequent chemical contact. Much like many other polyamide grades in the tecbond range, its benefits and usability stretch far beyond that of chemical resistance.

You may have heard the phrase “open time” when reading about adhesives but not known what it means or what it represents. Open time is an important factor to consider when choosing the correct adhesive for the job. Below, we will go into what open time is and why your use cases and working conditions can affect it.

One of the best-selling formulations in the tecbond range, tecbond 248 takes hot melt glue sticks to a new level in performance bonding. Used in both the construction and product assembly industries, its strong bonding properties, coupled with a good open time and fast setting speed, make it the go-to adhesive for tradespeople.

The spraytec system from Power Adhesives is a pioneering, innovative, and sustainable technology to replace solvent-based aerosol adhesives. Contrary to its name, the unique application method does not atomise the adhesive but instead creates a swirl pattern, ensuring a wide area of coverage with none of the drawbacks of traditional aerosol adhesives.

For over 10 years, Power Adhesives has been manufacturing specialised 43mm adhesive slugs designed to be applied via a unique spray-like application. The pioneering grades of this range, spraytec 410 and spraytec 420, not only provide users with a safer alternative to aerosol-spray adhesives but also allow them to use hot melt adhesive in situations where it would previously have been impossible.

The tecbond range of adhesives features many grades suitable for woodworking applications, with some specializing in bonding specific types of wood. Compared to traditional water-based or polyurethane wood glues, tecbond hot melt adhesives offer users a simple and effective solution to common bonding problems raised by woodworking applications.

Polyolefin plastics such as polypropylene and polyethylene have always proven difficult to bond. Many adhesives are unable to effectively wet the surface of these plastics to form a chemical bond, or to penetrate the polymer chains to form a physical bond.
