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.

Specification of Chlorinated polypropylene resin

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). (mPa.s@25°C/20% solids)

Package of Chlorinated polypropylene resin:

Chlorinated polypropylene resin is usually packed into 20kgs per carton.
