Polyurethane reactive adhesives are a type of adhesive that cure through a reaction with moisture. This curing process results in strong, flexible bonds that can adhere to various substrates, including wood, metal, plastics, and composites. Unlike traditional adhesives, PUR adhesives offer superior performance in demanding environments.

PUR polyurethane hot melt adhesive is a more advanced type of hot melt adhesive, known for its excellent bonding performance and durability. Unlike traditional hot melt adhesives, PUR adhesives react with moisture in the air during the curing process, forming a robust polyurethane structure.

When it comes to profile wrapping, finding the right adhesive can make all the difference in achieving a professional finish. Among the various options available, PUR (Polyurethane Reactive) hot melt adhesive has gained popularity as one of the best choices for this application. In this article, we will explore why PUR hot melt adhesive is often considered the top choice for profile wrapping, its benefits, and how to use it effectively.

In the production process, initial adhesion is a key indicator of adhesive performance. Good initial adhesion ensures that components remain in the correct position while the glue has not fully cured, preventing displacement during subsequent handling or transportation. This is especially crucial in winter conditions where low temperatures may affect adhesion, making relevant testing essential.

Polyurethane adhesives are synthetic adhesives made from a reaction between polyols and isocyanates. They come in different forms, including one-part and two-part systems, allowing for a wide range of applications. Once cured, these adhesives form a robust, flexible bond that can withstand various environmental challenges.
