Endex™ 155

High softening point, low molecular weight resin produced by copolymerization of pure aromatic monomers. Used as a modifier resin in high performance coating compositions. Offers very good color and color stability, no odor, very good resistance to thermal and oxidative degradation, good UV stability, narrow molecular weight distribution, and high glass transition temperature (98°C). Gives compatibility with polystyrene, rosin and modified rosins, rosin esters, styrene-butadiene rubber (SBR), and styrene based block copolymers.
