PUR hotmelt low pressure molding
PUR Hotmelt Adhesive

       PUR hotmelt adhesive is a moisture curing reaction polyurethanes hotmelt adhesive. It is a kind of reactive hot melt adhesive solidified after reaction with water molecules. Under the condition of inhibiting the chemical reaction, the PUR is melted by heating, and the PUR between the two products are condensed and cooled to serve as positioning function (physical reaction). Then, by means of the moisture in air and the moisture on the surface of the adhesive, it can expand the chain to form a polymer (chemical reaction) with high cohesion. The adhesive strength, heat resistance and low temperature resistance will be further improved. After complete solidification, it has excellent bonding strength, solvent resistance, paint resistance, heat resistance, hydrolysis resistance, etc.
