Water-based viscosifying emulsion plays a very important role in water-based acrylic pressure sensitive adhesive, which can improve the bonding strength and initial adhesion of pressure sensitive adhesive on high and low energy surfaces, so as to achieve the best balance point, and can improve the application range and grade of pressure sensitive products.

Today, we will take you to understand the application of water-based viscous emulsion in water-based pressure sensitive adhesive.

The adhesive emulsion plays a very important role in the pressure sensitive adhesive. It has a significant effect on the improvement of the peeling strength and initial viscosity of the adhesive. Depending on the adhesive polymer, different tackifying emulsions should be selected.

Aqueous rosin viscosification emulsion is a rosin modified emulsion dispersion with 55% high solid content, 100% solvent free and APE free. It has a very narrow particle size distribution interval and a small average particle size, which is used to improve the adhesive properties of waterborne pressure sensitive adhesives/adhesives.It has excellent low foamability, storage and mechanical stability. It has excellent compatibility with common polymers such as acrylic acid, SBR and NR.

Water-based adhesive emulsion is used for pressure sensitive adhesive, paper adhesive, industrial tape, film adhesive and other water-based adhesive.
