Proprietary Grade: NDEVPOL™ BIO
Used as a renewable, bio-based polyol component in polyurethane coatings, adhesives, sealants and elastomers. A separate higher-hydroxyl-value grade should be quoted for flexible/rigid foam customers rather than using this coating-grade specification.
Tested and certified in our laboratory according to official AOCS, ISO, ASTM, BP, USP, and EP compendial methods.
