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). (mPa.s@25°C/20% solids)
