pressure sensitive adhesive

The use of emulsion acrylic pressure-sensitive adhesive, for low surface energy substrates such as polyolefin surface adhesion, is poor. Therefore, tackifiers often need to be added to improve their sticking performance. Viscosifying resin was usually mixed with rosin resin as an emulsion acrylic pressure-sensitive adhesive. Rosin resin source is an acidic natural resin extracted from […]

water-based acrylic structure pressure sensitive adhesive

Water-based acrylic resin is generally divided into water-based emulsion type acrylic resin and water-based solid acrylic resin. Water-based emulsion acrylic resin, generally can be seen are water-based emulsion-type acrylic resin, that is, the acrylic emulsion is often said. It’s an emulsion acrylic resin. This kind of product does not take methyl acrylate monomer down reaction, […]
