PUR hot melt adhesive compared with water-based pressure sensitive adhesive
First of all, this is caused by the white material itself or contamination by the adherent. The water-based PU adhesive will not yellow. In the market, we usually encounter white PU / PVC bonded to rubber.
Advantages of PUR hot melt adhesive
Water-based pressure-sensitive adhesive does not contain any organic solvents, and the solid content is 100%, which is green and environmentally friendly;
The tape master roll is mainly based on the BOPP film master roll. After the BOPP film is treated with the high-pressure corona tape master roll, the surface is roughened, and the semi-finished master roll is then heated to uniformly coat the water-based pressure-sensitive adhesive.
How to use water-based pressure-sensitive adhesive
Nantong Jinwang Adhesive Products Co., Ltd. always adheres to product quality as its lifeline, continuously increases product technology investment, and strengthens quality supervision.
The role and precautions of water-based pressure-sensitive adhesive
Water-based pressure-sensitive adhesive has higher peeling force, higher peeling strength, good initial adhesion and retention.
Judging the quality of pressure-sensitive adhesive
Ordinary manual bonding workers determine the quality of water-based pressure-sensitive adhesives. Generally, they can be measured in terms of adhesion strength, drying speed, viscosity, solid content, and PH value.
