Silicon resins can be roughly divided into three categories according to the different substituents of silicon atoms on the silicon oxygen chain: monosubstituted silicone resin, mixed substituent silicone resin and modified silicone resin. Monosubstituted silicone resin mainly includes polyalkyl silicone resin and polyaryl silicone resin, and the main products include methyl silicone resin, vinyl silicone resin and phenyl silicone resin. Mixed substituent silicone resin mainly refers to polyalkyl aryl silicone resin, and the main products include polymethyl phenyl silicone resin and poly ethyl phenyl silicone resin. Modified silicone resin refers to the introduction of other resins to modify silicone resin. Its main products include epoxy modified silicone resin, polyester modified silicone resin, polyurethane modified silicone resin and phenolic modified silicone resin.

There are several other classification methods for silicone resin, which can be divided into varnish, insulating paint, paint, adhesive, silicone molding compound, resin powder, etc. according to the use and form; According to curing mode, it can be divided into condensation type, addition type, peroxide type, etc., and condensation type is the most common; According to curing conditions, it can be divided into heating curing type, normal temperature drying type, normal temperature curing type and light curing type.
