Resulting Properties

This formulation offers nicely balanced pressure sensitive adhesive performance with exceptional adhesion and shear properties. The pressure sensitive adhesive starting point formula serves as a basic reference tool for formulators. This formula can be readily modified to specific application (see source document). It is evident that the delicate relationships between the oligomers, co-resins, different types of monomers and photoinitiators must be perfectly balanced in order to achieve a functional and optimized pressure sensitive adhesive.
