? ?? CB-840S is an Adhesion Promoter made by high-performance modified chlorinated polypropylene resin. It is based on a special chlorinated polypropylene resin. By adjusting the molecular weight and modifying it with other resins, CB-840S greatly improves its adhesion on non-polar materials such as PP/OPP/BOPP; it can also better improve its adhesion on polar materials such as ABS/PET/aluminum foil.?
? ? ?CB-840S is a transparent liquid with ethyl acetate as the main solvent. It has good compatibility with chlorinated polypropylene resin, Polyurethane Resin, polyketone resin, rosin resin, etc. It can also be mixed with a small amount of acrylic resin, CAB Resin, chlorine and vinegar resin. For solvent-based inks and coatings, the generally recommended addition amount is 0.3%-1%.CB-840S can be added after grinding.
