Description
[Hercules] A brand name for a synthetic thermoplastic resin used as a tackifying agent in elastomeric adhesives. Pentalyn® H is a stabilized penta resin composed of Pentaerythritol ester of wood Rosin. The hydrogenation stabilization process increases its resistance to oxidation, discoloration, and adhesion loss. Pentalyn® H is a tackifying agent in natural rubber, Neoprene, and SBR formulations for use as pressure sensitive and hot-melt adhesives.
