1. Introduction:
Superchlon 822S is based on chlorinated polypropylene resin and is used as a primer for polypropylene materials. Polypropylene plastic has low weight, low cost, and excellent physical properties, chemical resistance, and heat resistance, making it widely used. However, its crystal structure and non-polar surface make adhesion difficult, limiting its application. However, Superchlon 822S can solve this problem because it has excellent adhesion to polypropylene plastics and topcoats made of polyurethane, acrylic, amino, epoxy, or alkyd resins. Superchlon 822S is commonly used as an adhesion promoter in polyolefin automotive bumper coatings. In addition, Superchlon 822S can also establish structural adhesion between polypropylene and other materials such as aluminum foil, fiber paper, polyester, and other plastics.

4. Compatibility:
Superchlon 822S mixed with other resins can enhance the adhesion between the primer and topcoat. Compared with traditional low chlorinated polyolefin resins, Superchlon 822S has been improved to enhance its adhesion to other resins. The following is the compatibility data between Superchlon 822S and other resins. Please note that if the proportion of other resins mixed is too high, it will reduce the adhesion to the polypropylene substrate. It is recommended that the proportion of other resins mixed should not exceed 30% by weight.
