USE
Manufacturer: Coim, Croda, Elementies/Deuchem, Invista, Polychem Resins
Outstanding properties: compatibility with polyethers, additives and blowers; excellent wetting
of rigid and fibrous substrates providing hardness, flexibility and good adhesion, good pigment
dispersability; good light stability, chalking resistance and good gloss retention; cost competitive
in comparison to conventional polyols; have similar hydroxyl values to castor oil, and can be sub-
stituted on a nearly equal weight basis
Recommended for resins: PU
Recommended for products: adhesives, coatings, automobile refinish, transportation and indus-
trial applications, metal coating, wood finish
