Scotch-Weld Polyurethane Reactive Adhesives

Due to the speed and comfort it does not stand out for traditional hot melt adhesives, but they offer an incomparably stronger adhesive! That’s why – hot melt glue reaches its highest strength after hardening, with polyurethane reactive adhesive after hardening, everything just starts. Further work is continued with a heated chemical reaction (temperature +121^оС).
The polyurethane reactive adhesive agent is used with a convenient and simple 3M PUR Easy 250 pneumatic applicator gun Applicator gun 3M PUR Easy 250. With its help, the thin, flexible and invisible glue thread is extracted, it allows to improve the fastening of details and the appearance and durability of products.
