Organic silicon coating crosslinking agent

Organic silicon coating crosslinking agent,Organic silicon, organic silicon compound, it is to point to contain Si - C keys, and at least one organic group is directly linked to the silicon atoms compounds, habits are often those with oxygen, sulfur, nitrogen and other organic base connected to the silicon atoms compounds as organic silicon compounds.

With silica, among them the key (- Si - O - Si -) as the skeleton of polysiloxane, is the largest organic silicon compounds, and studies the deepest, the most widely used type of account for about 90% of the total amount above.

Organic silicon material has a unique structure:

(1) Si atoms on plenty of methyl shielding the main chain of the high-energy polysiloxane;

(2) C - H non-polarity, make the interaction force between the molecules is very small;

(3) Si - O bond length is longer, Si - O - Si key bond Angle is big.

(4) Si - O bond is 50% ionic bonding characteristics of covalent bond (directional covalent bond, ionic bond nondirectional).

The characteristics of

Because of organic silicon unique structure, with the performance of the inorganic materials and organic materials, with low surface tension, small viscosity-temperature coefficient, high compressibility and high gas permeability basic properties, and has high and low temperature resistance, electrical insulation, resistance to oxidation stability, weather resistance, flame retardant, hydrophobic, corrosion resistance, non-toxic, tasteless, and physiological inertia and other excellent properties, are widely used in aerospace, electrical, construction, transportation, chemical industry, textile, food, light industry, medical industry, including organic silicon is mainly used in sealing, bonding, lubrication, coating, surface activity, demoulding, foam, foam suppression, waterproof, moistureproof, inert filler, etc. With the steady growth of organic silicon quantity and variety, broader application field and the formation of chemical new material industry of its own system of important products, many varieties is no substitute other chemicals and essential.

Metabolism of organisms also need silicone participation, these organic silicon chemical formula is usually CH3 (SiOH). 3. Organic silicon for the body functions play an important role and has direct relationship with the absorption of minerals. The human body has an average of about 7 grams of silicon, which outnumber other important minerals such as iron. Iron and silicon is essential elements, is a very important role to maintain normal metabolism.

Organic silicon material according to its shape is different, can be divided into: silane coupling agent (organic silicon chemistry reagent), bioactive organic silicone, silicone (silicone, silicone emulsion, silicon surfactants), high temperature vulcanization silicone rubber and liquid silicone rubber, silicone resin, compounds, etc.

Is the basic structural unit of organic silicon products made of silicon, oxygen link, side chain is through the silicon atoms connected to a variety of other organic groups. Therefore, in the structure of the organic silicon products containing both "organic groups", and "inorganic structure", the special composition and molecular structure to make it combines the characteristics of organic matter and inorganic matter functions in one. Compared with other polymers, organic silicon products the most outstanding performance is:

Organic silicon products based on silicon (Si - O - oxygen key chain structure, C - C key in the key for 82.6 kcal/mol, Si - O can key in the key of 121 kcal/mole in the organic silicon, so organic silicon products is high, the thermal stability of high temperature (or radiation exposure) molecular bonds do not broken, do not break down. Organic silicon not only resistant to high temperature, and low temperature resistant, can be used in a wide range of temperatures. Chemical properties and physical and mechanical properties, along with the change of temperature are small.

Organic silicon products main chain - Si - O -, no double bonds exist, therefore not easy by uv and ozone decomposition. Organic silicon is better than other high polymer materials and the thermal stability of the irradiation resistance and weather resistance ability. The service life of organic silicon in the natural environment can be up to several decades.

Main chain of organic silicon is very smooth, the intermolecular force is much weaker than hydrocarbons, therefore, than with low molecular weight hydrocarbons viscosity, surface tension, surface energy is small, film forming ability. This kind of low surface tension and low surface energy is the main reason why it for various applications: hydrophobic, foam, foam stability, adhesion, lubrication, polishing, and other excellent performance.
