Casttec: The hot melt system for the precast concrete industry

| | Leave a Comment

The casttec system is the cost-effective, non-destructive way to create and customise moulds and forms used in the precast concrete industry.

The adhesives are designed to hold weld plates, foam inserts, wood, plastic, and metal reveals to steel and resin-coated surfaces throughout the concrete forming process. Once the forming process is complete, the adhesives can be easily removed from the finished form and mould.

Instant bonding with easy cleanup

Casttec adhesives bond almost instantly when substrate contact is made, with no need for holding or clamping to the surface. The high-power tec glue guns provide ample molten adhesive to cover large sections and long runs with ease.

All casttec adhesives have a generous open time, so they remain tacky for several minutes until substrate contact is made. This gives the user more time to position the inserts into the formwork without the adhesive setting. They can also be applied at an optimised temperature for more heat-sensitive substrates, such as polystyrene foam.

After 8–24 hours, depending on the grade, the adhesive crystalizes and becomes very brittle. This process means that not only can the insert be easily removed from the mould, but the adhesive residue can be effortlessly scraped from the substrates without causing damage. Other methods of attaching these inserts can damage the formwork or be more time-consuming to remove once the concrete has set.

Environmentally friendly

All the adhesives in the casttec range are solvent-free and non-flammable, making them far safer and kinder to the environment than aerosols and solvent-based adhesives. Available in 43mm slugs and small pillow format for bulk applications, the adhesives are safe to handle, have an unlimited shelf life and don’t have any special storage requirements.

The casttec range of adhesives is designed to work in partnership with the tec range of industrial glue guns to achieve maximum output and efficiency. This includes the tec 3400 as well as the 6000 and 7000 series guns. The applicators melt the adhesive on-demand, enabling continuous use with no downtime. Any unused glue left in the gun can be remelted the next time the gun is switched on.

The two types of bonding – Physical and chemical

When forming bonds with adhesive, it is not as straightforward as the adhesive just sticking two materials together. Depending on the materials being bonded, the adhesive will form bonds using a combination of two different mechanisms: physical bonding and chemical bonding. While both are important, these bonds operate in different ways, each with its own […]

Tecbond 213 – The economical all-purpose adhesive

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. What is tecbond […]

Tecbond polyamide adhesives: Everything you need to know

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 […]
