POLYBOND™ Polypropylene-Based Coupling Agents are coupling agents, compatibilizers, and adhesion promoters for plastics, elastomers, glass, mica, talc, wood, and natural fiber. Its reinforced polypropylene promotes enhanced physical and thermal properties in a variety of polymers and applications.
POLYBOND™ 7200 is an excellent choice for enhanced adhesion, gloss, and speed in Polypropylene plastics and BOPP lamination applications.
