Formulating Pressure Sensitive Adhesives

摘要

1. Solvent borne 1.1 Polymer actually dissolved in solvent blend 1.2 Viscosity increases with solids and MWD 1.3 May be cross-linked upon drying 1.4 Hot Melt 1.4.1 Polymer 1.4.2 Viscosity decreases with temperature 2. Water borne 2.1 Polymer in discrete particles 2.2 Particles stabilized by surfactant 2.3 MWD and viscosity mostly independent.
