SORESYN® CPP Resin is a thermoplastic resin produced by chlorination modification of polypropylene excellent adhesion to PP, PE, EPDM & TPO materials, widely used in coatings (especially composite inks) and adhesives.
It is non-toxic, inodorous, has no solvent residue. It is water-resistant, acid-resistant and alkali-resistant. The composite ink made by CPP has stable performance and good filming property.

Dissolve Soresyn® CPP Resin in toluene to prepare a 10–20% solution before use. It can also be blended with other higher-polarity resins. Handle with care to avoid contact with skin and eyes.
SORESYN® CPP exhibits excellent adhesion to polypropylene surfaces, as well as good adhesion to polyethylene, paper, aluminum foil, and other materials. It also offers good hardness, wear resistance, saltwater resistance, and aging stability. Therefore, CPP is widely used in printing inks, plastic and metal adhesives, and is particularly suitable for producing printing inks for composite materials such as double-layer PP film, PP-paper, and PP-aluminum in the packaging industry. Additionally, it finds applications in coating color carriers and waterproofing agents. Due to the presence of chlorine atoms on its molecular chain, CPP is also used in flame retardants.
