Reactive hot melt adhesives are advanced adhesives that combine the properties of traditional hot melt adhesives with reactive components. These adhesives are applied in a molten state and solidify upon cooling, similar to standard hot melts. However, what sets them apart is their ability to undergo a chemical reaction during the curing process, significantly enhancing their performance.

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.
