Excellent Adhesion Chlorinated Polypropylene CPP Superchlon 814HS
For Polyurethane Coatings
Chlorinated Polypropylene resin DR-540S is a newly developed
high-performance chlorine modified resin, which is composed of
isogenized high-grade PP chlorinated and grafted with functional
groups.

Properties of Chlorinated polypropylene 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%.
It 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).
