Proprietary Grade: NDEVPOL™ DCO
Used as a semi-drying/drying oil in paints, varnishes, alkyd resins, printing inks, primers, caulks, sealants and protective coatings. Its increased unsaturation (largely conjugated diene) enables oxidative drying and film formation.
Tested and certified in our laboratory according to official AOCS, ISO, ASTM, BP, USP, and EP compendial methods.
