Good Adhesion Chlorinated Polypropylene CLPP Superchlon 814HS For
Coating Systems
Chlorinated Polypropylene DR-540S has excellent adhesion to various
types of PP/PE plastic materials, and has a good affinity with most
commonly used solvent-based resins, which is widely used in
advanced coating systems.

Properties of Chlorinated polypropylene resin:
CPP resin DR-540S has excellent adhesion to various substrates such
as PP, BOPP, etc., and has good compatibility
with acrylic resin, polyurethane resin, alkyd resin, etc. The
amount of it added to polyurethane inks is generally 1-2%.
Chlorinated polypropylene resin DR-540S is easily soluble in solvents such as ketones, benzene,
esters, alcohols, etc., so it is a good environmentally friendly
adhesion promoter in polyurethane coatings/inks.
Solubility of Chlorinated polypropylene resin:
Soluble solvents:
Aromatic hydrocarbons - toluene, xylene, etc
Aliphatic hydrocarbons - cyclohexane, methylcyclohexane,
ethylcyclohexane, etc
Ketones--- MEK, MIBK, etc
Esters--- ethyl acetate, butyl acetate, etc
Slightly soluble solvents:
methanol, ethanol, butanol (alcohols); Hexane, heptane (alkane).
