Coupling agents are multifunctional compounds designed to provide a means for chemically coupling to both the inorganic surface and to the organic adhesive or coating. The most widely used coupling agents are based on organosilicon chemistry, although titanates and zirconates have also enjoyed modest technical and commercial success.
POLYBOND™ Polypropylene-Based Coupling Agents are coupling agents, compatibilizers and adhesion promoters for glass, mica, talc, wood, and natural fiber reinforced polypropylene giving enhanced physical and thermal properties. Learn More About POLYBOND™ 3200 as a Coupling Agent.
Modifier to improve the mechanical properties and adhesion of filler, glass fiber, carbon fiber and natural fiber compounds. As adhesion promoters and coupling agents, BYK additives create stable and additional bonds between phases. Find out more here.
30 de jun. de 2022 · When adhesion promoters are used to increase the adhesion between a polymeric system and a filler, they are called Coupling Agents (mode of action). Chemically these are the same materials in both cases. Adhesion promoters can be reactive or non-reactive.
1 de jan. de 2011 · Adhesion promoters, or coupling agents, are chemicals that act at the interface between an organic polymer and an inorganic surface to enhance adhesion between the two materials. This chapter discusses the inherent chemical and physical nature of organosilane coupling agents that are used as adhesion promoter.

Compounds acting as interfacial agents are commonly known as “compatibilizers” in blends, or “coupling agents” in composites; their function is to promote adhesion and enhance overall properties. This paper is a review of recent advances in the use of these compounds in immiscible polymer blends and thermoplastic composites.
