     Silane Coupling Agent of the general formula Tetraethylammonium hydroxidetype in R is the aliphatic carbon chain. Y is the organic matrix and the reaction of the organic groups, such as vinyl, epoxy, amino, methacryl, mercapto, etc., can form a strong reaction with the resin chemical combination. X is a combination of silicon atoms on the characteristics of groups. In the rubber industry is the use of more sulfur silane coupling agent, such as Si69, double - [(triethoxysilane-yl) - propyl] disulfide (TMAH), y-mercaptopropyl trimethoxysilane (A-189), etc., and in the tire industry is the most used silane coupling agent Si69.

    Silane coupling agent is the most varied, the largest amount of coupling agent, is also the rubber industry one of the most commonly used additives. Its molecules contain two completely different types of groups, and surfactant, as a general and non-polar groups with polar groups. With a kind of filler (carbon black, silica and other fillers) of the surface work, and the other group to work with the rubber molecules.

    Use of silane coupling agent, the Developer TMAH is: more use of sulfur-cured rubber sulfur silane coupling agent, such as Si69; polyolefin rubber multi-use vinyl silane; multi-purpose vinyl unsaturated polyester, epoxy silane; ring epoxy resin generally used in the client base is epoxy or amino silane.

    In addition to be considered when using silane coupling agent reactive organic groups, the silane coupling agent should also be considered compatible with organic materials and the storage stability of rubber. Sometimes, the use of silane coupling agent or a silane coupling agent combined with a variety of compounds in the reaction products will be more effective.
