Eastman adhesion promoters

Applying paint to polypropylene and thermoplastic polyolefin (TPO) is difficult because of the poor adhesion of most coatings to plastics. Eastman chlorinated polyolefins (CPOs) are widely used as adhesion promoters for coatings and inks on polyolefin plastics such as untreated polyethylene, polypropylene, or TPO. Our chlorinated polyolefins serve as adhesion promoters in at least three ways:

  • As a primer between the substrate and subsequent coatings
  • As a primer or tie coat between coatings layers
  • As an additive to the paint or ink

Eastman Advantis™ adhesion promoters

Eastman has introduced the next generation of adhesion promoters to keep u​sers compliant with regulatory changes. Advantis adhesion promoters​ limit or remove materials of concern, so formulators and end users can deliver dependable results to customers while improving product sustainability and meeting regulatory requirements.

Waterborne CPO adhesion promoters

Eastman CPO dispersions let users apply an adhesion-promoting primer from a waterborne system or promote adhesion of a waterborne coating through use as an additive. Eastman CPO dispersions are useful as base resins in adhesion-promoting primers and as additives to waterborne coating formulations to improve adhesion to polypropylene-based substrates.

Nonchlorinated adhesion promoters

Eastman offers nonchlorinated adhesion promoters that provide excellent adhesion to TPO and polypropylene substrates. Additionally, formulators can now select a waterborne adhesion promoter that is chlorine and AEPO free. Used as a blend-in additive for waterborne primers and/or base coats, these products enable the development of VOC-compliant coatings for adhesion to modified polypropylene substrates.
