What is RTV Silicone?


RTV is the abbreviation of Room Temperature Vulcanizing in English, and it is a room temperature vulcanizing silicone rubber adhesive. RTV silicone is a semi-flowing temperature-resistant paste silicone adhesive sealant without curing, which has excellent sealing and bonding properties. The cured colloid has good sealing, waterproof, moisture-proof, shockproof and insulation. Performance, non-toxic, non-polluting, non-corrosive, can reach the environmental protection level. It also has excellent temperature resistance, and the operating temperature range is -60 to 200°C. Widely used for fixing and reinforcing electronic components, cavity sealing, waterproof protection, etc. It is also suitable for sealing, filling, bonding, and packaging in high-temperature applications, such as high-temperature kitchen appliances, electric irons, and air purifiers.

The appearance of RTV silicone is a viscous liquid, and the appearance colors are transparent, black, white, etc., which can be formulated according to user needs. RTV silicone is prepared by compounding silicone rubber, crosslinking agent and filler. Usually, the two ends of its molecular chain contain active groups such as hydroxyl and vinyl groups. The structure is similar to silicone oil. It is a solvent-free, non-toxic Corrosion of RTV silicone rubber. Long storage period and stable performance.

RTV silicone performance characteristics:

1. After curing, it becomes an elastic colloid, which has excellent shock resistance. When vibration occurs, the elastic colloid can play a protective role and is not easy to break.

2. Convenient vulcanization, can be vulcanized at room temperature, and can be cured without heating. After curing, it will not shrink or release toxic substances, and its performance is safe and guaranteed.

3. Long storage period and stable performance. During storage, without the ingress of air or moisture, the performance remains the same and the bond is strong.

4. After curing, it has good electrical insulation and arc resistance, excellent bonding and sealing performance, and high temperature resistance, and can be used for a long time in the temperature range of -60 ° C to 200 ° C. It can meet the requirements of most electronic appliances and is safer to use. Even if an electrical short circuit occurs, it will not cause a fire.

5. It has a wide range of applications, and is widely used in bonding, fixing, sealing, potting, heat conduction and coating in electronics, electrical, automotive and general industrial fields. The performance is stable and will not change after many years of use.

6. Environmentally friendly, non-toxic and non-corrosive. After curing, it will not corrode metals, ceramics, plastics, circuits, etc. Even if it encounters high temperature after curing, it will not decompose and release harmful gases or substances that affect human health. It can be used safely for household appliances and high-temperature kitchen appliances.

7. It has excellent corrosion resistance, weather resistance and aging resistance, and can be used even in some harsh environments.

RTV silicone has become an indispensable material in the manufacturing process of electronic appliances, automobiles, instruments, high-temperature kitchen appliances and other fields. TENSAN RTV silicone has high and low temperature resistance, weather resistance, aging resistance and other formulas. If the demand is large, it can be used in large quantities. Purchase, just pay attention to storage.
