One component condensed RTV silicone rubber

One component condensation type adhesive is a mixture of polydimethylsiloxane as the base polymer, silica, nano calcium as powder, supplemented by crosslinking agent, coupling agent, catalyst and so on. Sealed and stored in rubber hose before use, open contact air vulcanization to form elastomer, sealed and stored after use.

Application industry: construction, that is, often said glass glue, glass curtain wall bonding;
Industrial adhesive is often said to be electronic silica gel, used in electronics, lighting, photovoltaic, etc., bonding, fixing, sealing;
Type of glue: acid glue, release small molecule acetic acid CH3COOH
Ketone oxime glue, release small molecule butanone oxime CH3 (CH2CH3) C=NOH
Methanol glue, release small molecule methanol CH3OH
Ethanol glue, release small molecule ethanol CH3CH2OH
Acetone glue releases small molecule acetone CH3COCH3

One component condensation type adhesive has excellent electrical properties, vulcanization properties and mechanical properties, good temperature resistance, generally in -40-200℃ can be used for a long time, its outstanding advantages make its application is very wide.

One component molding RTV silicone rubber
One component plus molding RTV silicone rubber is a mixture of vinyl sealed poly (diorganosiloxane) as the base glue, methyl containing hydrogen polysiloxane as the crosslinking agent, supplemented by fillers, catalysts, inhibitors and other components, packaged together. When used, the vinyl of the base glue and the silicon-hydrogen bond in the crosslinking agent will undergo silicon-hydrogen addition reaction under the platinum catalyst, and is vulcanized into a network of elastomers.

Single component plus molding glue, is also packaged in a tube, packaging appearance and single component condensation type glue is similar, but its composition, vulcanization mechanism is very different. One component condensation type adhesive encapsulated in a tube, as long as it does not contact the air can keep its good storage; And single component plastic, it is under the condition of platinum catalyst vinyl and silica-hydrogen bond cross-linking reaction, without contact with the air can be vulcanized, so the storage of single component plastic plastic has become a bigger problem, in addition to the bonding of plastic is another big problem. But it can accelerate its deep vulcanization through high temperature, vulcanization rate is far more than the condensation type, greatly improve the work efficiency, widely respected.
