Heat resistant Curabond hot melt powders with a degree of cross-linking

Curabond is used in a variety of applications where conventional thermoplastic powders do not meet requirements.

This range of products are supplied to many customers worldwide and are used in a wide variety of applications where conventional thermoplastic powders do not meet the necessary requirements such as heat resistance.

The base polymer of the Curabond range melts around 100 – 110°C and on additional heating the melt viscosity increases to a point of infusibility. The ideal temperature for cross-linking the product is 165 – 170°C. Depending on temperature/time, it is possible to react products within the range enough to withstand temperatures up to 250°C.

The polymer chain has a large proportion of polar chemical groups which facilitate excellent adhesion to a wide variety of substrates including metallised foils and glass fibre. It also exhibits excellent adhesion to Aramid, carbon fibre and substrates with difficult finishes such as fluorocarbon and silicone.

This range of products are currently being used in many different applications where high heat resistance is required. It particularly lends itself to deep draw moulding applications for the automotive sector.

Curabond has the advantage of simple application as with standard hot melt powders and a "stop-start" reaction system which does not require moisture, UV, or catalyst and is therefore stable at low and ambient temperatures requiring no special storage conditions and a shelf life measured in years.

It is available in different particle sizes for both scatter and powder point coating.
