Silane Coupling Agent - an overview | ScienceDirect Topics
Typical silane coupling agents include (3-aminopropyl)-triethoxymethyl silane (APTES), (3-aminopropyl)-diethoxymethyl silane (APDEMS), and aminopropyldimethylethoxy silane (APDMES). The addition of silane coupling agents can increase the interaction between polymer and filler by forming a chain linker between inorganic fillers and polymers.
Silanes with two hydrolyzable groups form less rigid interfaces than silanes with three hydrolyzable groups. They are often used as coupling agents for elastomers and low modulus thermoplastics. Polymeric silanes with recurrent trialkoxy or dialkoxysilanes offer better film-forming and primer capabilities.
Adhesion Promoters: Silane Coupling Agents - ScienceDirect
2011年1月1日 · Silane coupling agents act in the interphase region, the area between an inorganic substrate and an organic substrate, and act as a bonding, or bridging, agent to improve the adhesion between the two dissimilar materials.
Silane coupling agents are compounds whose molecules contain functional groups that bond with both organic and inorganic materials. A silane coupling agent acts as a sort of intermediary which bonds organic materials to inorganic materials.
