Hot-melt pressure-sensitive adhesives are the third generation of pressure-sensitive adhesives after solvent-based and emulsion-based pressure-sensitive adhesives. Compared with the first two, hot-melt pressure-sensitive adhesives are solvent-free, more environmentally friendly, safer in production, high in production efficiency, and relatively low in production costs.
Characteristics of pressure sensitive adhesive:
1: Have long-lasting high viscosity.
2: Only need to apply pressure with hands or fingers during application.
3: No need to activate by water, solvent or heat.
4: There is a strong adhesive force.
5: There is sufficient cohesion and elasticity.
Advantages of pressure sensitive adhesive:
1: Quickly sizing without mixing or brushing.
2: Uniform glue amount.
3: Can be die-cut into special shapes.
4: It has viscoelasticity and eliminates brittleness.
5: The smell is small when in use.
