Poly BD R20LM

Low molecular weight hydroxyl terminated polybutadiene resin. Has primary, allylic alcohol groups that exhibit high reactivity in either condensation polymerization reactions or the preparation of derivatives. The degree of polymerization is approximately 25 for the POLY BD R20LM and the molecular weight is 1200. Possesses hydrophobicity, low glass transition temperature gigh solid loading properties, low color and high clarity. Exhibits low moisture permeability, resistance to aqueous acids and bases, low temperature flexibility as well as electrical insulation properties. Used in waterproof coatings and membranes.
