What is the main component of silicone primer

29 Oct 2019

Generally speaking, silica gel can be divided into organic silica gel and inorganic silica gel according to its properties and components.

It is a kind of highly active adsorptive material, which can be purified from natural mineral to be granular or beaded.

Silica is a porous structure, containing numerous holes, spongy;

Holes can absorb water, which is why silica is widely used in the production of silicone treatment agent.

Chemical stability, no combustion.

Silica gel is a kind of amorphous silica, should control the workshop dust content is not more than 10 mg/m3 silica gel was mostly carbon dioxide, the main composition of silica gel treatment agent is silica, environmental non-toxic inorganic silica gel is a highly active adsorption organic non-toxic material, usually is to use sodium silicate and sulfuric acid reaction, and the aging, acid soak and a series of post-processing process and system.

Silica gel is an amorphous substance, its chemical formula is mSiO2.


Insoluble in water and any solvent, non-toxic tasteless, stable chemical properties, except strong alkali, hydrofluoric acid and no substance reaction.

Different types of silica gel have different microporous structures depending on how they are made.

The chemical composition and physical structure of silicone agent determine that it has many characteristics that are difficult to be replaced by other similar materials: high adsorption performance, good thermal stability and chemical properties.
