Product Overview
CP 343-1-40% is a 40% solids solution of CP 343-1 in xylene. This chlorinated polypropylene polymer is used to prime untreated polypropylene, TPO, and metal surfaces to allow for improved adhesion of paints, coatings, inks, and adhesives. Primers formulated with CP 343-1-40% offer outstanding humidity resistance and are ideal for use in marine climates.
Product Specifications

Features & Benefits
Excellent primer in PP, TPO, Non-olefin plastics and metal substrates
Excellent humidity resistance
Modification of CP343-1 with ethylene vinyl acetate increases the softening point and cohesive strength of primer film.
Problems Solved
Priming resin is difficult to solvate and reduces production efficiency.
Poor adhesion of primers in humid conditions.
Applications
Primers; Architectural Coatings; Industrial Coatings; Marine Coatings; Adhesives & Sealants; Printing Inks
