Features Of Eastman CP 343-1-100% Chlorinated Polyolefin Adhesion Promoter

  1. Enables strong, durable adhesion of paints, inks, and coatings to low-surface-energy polyolefin substrates including PP and PE.

  2. Offers excellent compatibility with a wide range of solvent-based and high-solids coating systems.

  3. Provides superior resistance to humidity, thermal cycling, and mechanical abrasion after curing.

  4. Delivers consistent performance without requiring surface pretreatment such as flame or corona treatment.

  5. Formulated as a 100% active chlorinated polyolefin—no solvents or diluents added.

Typical Applications Of Eastman CP 343-1-100% Chlorinated Polyolefin Adhesion Promoter

  1. Automotive interior trim coatings (e.g., instrument panels, door panels, and center consoles).

  2. Appliance housings and decorative plastic components requiring high-gloss or textured finishes.

  3. Industrial packaging films and laminated structures where ink adhesion to PP/PE is critical.

  4. Medical device housings made from polypropylene or polyethylene requiring reliable coating integrity.

  5. Consumer electronics enclosures requiring robust paint-to-plastic bonding under varying environmental conditions.
