PU Ink Adhesion Promoter
Low molecular weight CPP can serve as an adhesion promoter.
Primary Uses: Improves the adhesion of PU inks on PP (polypropylene) and PE (polyethylene) films.
Commonly used in packaging printing to resolve ink adhesion issues on low surface energy substrates.
Automotive Coatings / Adhesives
CPP exhibits strong affinity for polyolefin substrates such as PP and TPO. It offers excellent compatibility with resins like acrylics and polyurethanes, effectively enhancing coating adhesion.
Primary Uses:
Automotive bumper coatings (high flex-resistance grade)
Interior trim coatings (low VOC formulations)
Polymer substrate coatings (adhesion promoter tie-layer)
Adhesive formulations: Structural bonding such as PP to metal and PP to rubber
Chlorinated Inks (Printing Ink Applications)
High molecular weight CPP resin specifically developed to boost ink adhesion on PP substrates.
Suitable for both benzene-soluble and ester-soluble ink systems.
Commonly used in packaging printing to eliminate the issue of ink peeling off PP film surfaces.
