Application of silicone products in silicone electronic potting adhesive

Potting is the process of filling solid or gelatinous compounds into complete electronic assemblies in electronic technology to resist impact and vibration and remove moisture and corrosive substances. It has the functions of water-proof, moisture-proof, dust-proof, insulation, heat conduction, confidentiality, corrosion resistance, temperature resistance and shock resistance. These gels used for electronic components and circuits are called electronic potting adhesives.

Epoxy resin, polyurethane elastomer and organosilicon polymer are the most widely used electronic potting adhesives. Among them, the silicone polymer material is widely used in the potting protection of electronic and electrical components because of its unique climate and aging resistance, excellent high and low temperature resistance, good hydrophobic mechanical properties and electrical insulation due to its special silicon oxygen bond main chain structure.

107rtv silicone rubber of Hubei Zhuo xuanyang International Trade Co., Ltd. can keep elasticity in the temperature range of - 60 ℃ ~ 200 ℃ for a long time. It has excellent electrical performance and chemical stability, and can withstand water, ozone, climate and aging. It is widely used in the insulation, shockproof, moisture-proof, corrosion-proof of electronic components, the mold making and demoulding of rubber products, etc. 107 RTV silicone rubber makes silicone electronic potting adhesive have excellent high and low temperature resistance, weather resistance and electrical insulation, so it has a very wide range of applications in the field of electronic components packaging.

In addition to 107rtv silicone rubber, the company's dimethyl silicone oil, vinyl silicone oil and hydrogen silicone oil are also indispensable components of silicone electronic potting adhesive. According to the different reaction mechanism of silicone rubber, silicone electronic potting adhesive can be divided into condensation type silicone electronic potting adhesive and addition type silicone electronic potting adhesive.

The condensed silicone electronic potting adhesive is made of 107 silicone rubber (α, ω - dihydroxypolydimethylsiloxane) as the main body, methyl trimethoxysilane, dimethyldiethoxysilane, γ - aminopropyltriethoxysilane, TEOS and other silane coupling agents as the crosslinking agent, dibutyltin dilaurate as the catalyst.
Features: during the curing process, volatile low molecular substances will be produced, and there will be obvious shrinkage after curing.

The additive silicone electronic potting adhesive is made of vinyl silicone oil as the main body, hydrogen silicone oil as the crosslinking agent, catalyst, tackifier and inhibitor.
Features: no small molecules are produced in the curing process, and the shrinkage is small.
