Acid Modified Chlorinated Polyolefin

Acid-modified chlorinated polyolefin has an excellent adhesion to polyolefin substrates. Due to the introduction of polar groups, it also shows high performance of adhesion to substrates such as PET, ABS, and nylon, and to topcoat paints based on acrylics, polyurethanes, epoxies, and alkyds as well.

General Characteristics
