Organic silicone gel is a special type of organic silicone rubber, which is a substance called "solid-liquid coexisting material" composed of liquid and solid. This structure is composed of a network of polymer compounds, which exhibit unique properties due to their interactions. Before the curing of silicone gel, it is generally divided into two components: A and B. Under the catalysis of the catalyst platinum compound, the vinyl group (or propylene group) on the silicone-based adhesive undergoes an addition reaction with the silicon hydrogen group on the crosslinking agent molecule. No by-products are produced throughout the entire reaction process, therefore no shrinkage occurs throughout the entire vulcanization process.

The main characteristics of organic silicon gel

1. Stable physical and chemical properties, not greatly affected by temperature, can be used in a wide temperature range (65 ℃ -200 ℃), with excellent electrical insulation performance and high and low-temperature resistance (-50 ℃ -200 ℃).

2. The system is colorless and transparent, and after curing, it becomes a semi-solid state. It has good adhesion and sealing performance to many substrates. When used as a sealing material, it is convenient to observe the internal structure of the sealing component and has excellent resistance to cold and hot alternation.

3. After mixing the two components, they will not gel quickly, so they have a longer operational time. Once heated, they will solidify quickly, and the curing time can be freely controlled. Good fluidity and good self-leveling ability, able to inject into the subtle details of micro components in integrated circuits.

4. Organosilicon gel can physically adhere to the surface of most common electronic devices or other materials without the need to add adhesive agents or spray adhesives on the bonding surface before curing. There are no by-products produced during the curing process and no shrinkage.

5. Good self-healing ability, the gel can automatically heal after cracking under external forces, and it also plays a waterproof and moisture-proof role without affecting the use effect. Capable of replacing components for sealing components and conducting circuit testing for metal probes.

6. According to application requirements, the flowability, hardness, curing time, and other properties of the product can be regulated, and some fillers can be added to prepare conductive and thermal conductive silicone gels.

The main uses of organic silicon gel

The organosilicon gel is currently widely used as a moisture-proof, shock-absorbing, insulation coating and sealing material for electronic components, providing dust-proof, moisture-proof, shockproof, and insulation protection for electronic components and assemblies. Used for waterproofing, moisture-proof, and gas pollution prevention coating, pouring, and sealing protection of precision electronic components, bathrooms, backlights, solar energy, connectors, electrical modules, discrete devices, and integrated circuit boards.

The organosilicon gel is an ideal inner coating material for transistors and integrated circuits, which can improve the grid rate and reliability of semiconductor devices. The organosilicon gel can also be used as an elastic adhesive for optical instruments.

By using transparent silicone gel to encapsulate electronic components, not only can it provide shock and waterproof protection, but also the components can be seen and their faults can be detected with probes for replacement. Damaged silicone gel can be resealed and repaired.
