Features Of Eastman CP 730-1 Chlorinated Polyolefin Adhesion Promoter

  1. Enhances adhesion of coatings, inks, and laminating adhesives to low-surface-energy polyolefin substrates such as PP and PE.

  2. Provides excellent compatibility with acrylic, polyester, and nitrocellulose-based coating systems.

  3. Offers good thermal stability during standard drying and curing processes (up to 120 °C).

  4. Delivers consistent performance in both solvent-borne and high-solids formulations.

  5. Enables improved interfacial bonding without significantly affecting substrate flexibility or clarity.

Typical Applications Of Eastman CP 730-1 Chlorinated Polyolefin Adhesion Promoter

  1. Automotive interior trim coatings on polypropylene (PP) substrates.

  2. Flexible packaging laminations involving polyethylene (PE) films.

  3. Industrial metal-over-plastic assemblies requiring durable paint adhesion.

  4. Appliance housings where decorative finishes must withstand humidity and thermal cycling.

  5. Medical device components requiring biocompatible coating adhesion on olefinic polymers.
