Functional silane and silicone rubber, silicone oil and silicone resin and called four categories of organic silicon materials.
In terms of structure, small organosilicon molecules whose main chain is -Si-O-C- structure are generally collectively referred to as functional silanes.
From the point of function, functional silane is a hybrid structure more, most of the products in the same molecule containing polar and nonpolar two types of functional groups at the same time, can be a interface bridge of inorganic material and organic material or directly participate in the crosslinking reaction of organic polymer materials, thus greatly improve the material performance, is a kind of very important and wide use of additives.
Functional silanes can be classified into two types: γ-substituted and α-substituted according to the relative substitutions of active organic groups to Si.
According to the types of substituents, the sulfur silane, amino silane, vinyl silane, epoxy silane, methacryloxysilane are the most widely produced and consumed in China.
According to their use, they can be divided into silane coupling agent and silane crosslinking agent.
