Phosphate Polymerizable Adhesion Promoters

By Hui Shirley Yang, Herve Adam, Jon Kiplinger

We describe novel applications of phosphate functional monomers in poly­mers obtained by radical polymerization. These polymers are designed to improve die dry/wet adhesion of coatings and adhesives on metal surfaces. Two phosphate monomers were incorporated smoothly into the polymer resins without major for­mulation or procedure change.

These monomers have been used in a wide range of applications to improve the properties on a variety of substrates. They dramati­cally improved adhesion as well as other related properties, such as wet scrub resistance and corrosion resistance, for the formulated coatings.
