Teckros® RP103 is a rosin phenolic tackifier characterized by high polarity and narrow molecular weight distribution, enabling excellent adhesive performance with various polymers. It enhances tack and adhesion in solvent acrylic PSAs, improves low-temperature performance in EVA hot melts, and serves as a co-tackifier and reinforcing resin with SBR, polychloroprene, and other polymers for applications like construction, contact, and laminating adhesives.
