Synthetic Adhesive to the surface of the adherend

Posted by WilliamNance on May 11th, 2017

PUR's adhesiveness and toughness (elasticity) can be adjusted, and has excellent bonding strength, temperature resistance, chemical resistance and resistance to aging. In recent years has become one of the important varieties of Lamination Adhesive . Is widely used in packaging, wood processing, automotive, textile, electrical and mechanical, aerospace and other national economic areas.

PUR can be divided into two categories: one is thermoplastic polyurethane hot melt adhesive, the other is reactive PVC hot melt adhesive, colloid heating and air after the reaction of moisture to form a high polymer polymer compounds.

Reactive polyoxyethylene hot melt adhesive characteristics can be cured in the environmental conditions, lower than the traditional hot melt adhesive application temperature.

Reactive hot melt adhesive is in the inhibition of chemical reaction conditions, such as hot melt into a fluid, in order to facilitate the coating; two kinds of sticky paste after cooling the adhesive layer to play a bonding effect; after the presence of moisture in the air .

The moisture and the moisture Synthetic Adhesive to the surface of the adherend are reacted with each other to expand the chain to produce a polymer having a high cohesive force, and the adhesion strength, heat resistance, and low temperature resistance are remarkably improved.
