Silicone resin is a semi-inorganic polymer with a silicon - oxygen - silicon main chain and an organic group connected on the silicon atom. Polysiloxane, having a highly intersecting, networked structure, is a highly branched polymer (as opposed to linear silicone oil) that can be cured into a solid. Both organic resin and inorganic material double characteristics, has a unique physical and chemical properties.
The properties of the final product of a silicone resin depend on the number of organic groups contained (i.e., the ratio of R to Si). In general, the ratio of R to Si in the molecular composition of silicone resins with practical value ranges from 1.2 to 1.6. The general rule is that the smaller the value of R: Si, the more the resulting silicone can cure at a lower temperature; The greater the value of R: Si, the obtained silicone resin to make it curing requires 200 materials at 250℃ for a long time to bake, the resulting film hardness is poor, but the thermal elasticity is much better than the former. Silicone also has excellent moisture resistance, waterproof, rust resistance, cold resistance, ozone resistance and weather resistance, the vast majority of aqueous chemical reagents such as dilute mineral acid corrosion resistance is good, but the performance of solvent resistance is poor.
