Abstract
A water compatible terpolymer for sealing and coating building materials which protects surfaces from environmental staining agents. The terpolymer is created by polymerizing a HEMA:SMA co-polymer with another monomer which contains either free acid or base groups. The resultant terpolymer is water solution after neutralization. Water is then added to bring the solvent level to 40% maximum and the solids level to 8%.
