【RTV Silicone Glue】What is it? What are the performance characteristics of RTV silicone rubber glue?

Studies have shown that the world's organic silicon is growing at a rate of about 6% per year, and RTV silicone, as one of the fastest-growing varieties, owes much to its excellent performance characteristics. The following Yantai adhesive application engineers will introduce RTV silica gel.

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. It has excellent sealing and bonding performance. 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 -60~200°C. It is widely used in the waterproof, sealing, bonding and fixing of electronic products, such as the waterproof sealing of electro-acoustic devices such as speakers and microphones and the housing, the waterproof sealing of the edge of buttons, the bonding and fixing of electronic components such as sensors, etc. Suitable for sealing, filling, bonding, encapsulation in high temperature applications, such as high temperature kitchen appliances, electric irons, air purifiers.

The appearance of RTV silicone is a viscous liquid, and the appearance colors are transparent, black, white, gray, etc., which can be formulated according to user needs. RTV silica gel is prepared by compounding silicone rubber, crosslinking agent, filler and other components. 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 mouth plays a protective role, and new cracks are not easy to occur.

2) It is easy to vulcanize, can be vulcanized at room temperature, can be cured without heating, will not shrink after curing, will not release toxic substances, and has guaranteed performance.

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 ~ 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 dry electronics, electrical, automotive and general industrial fields. It has stable performance 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, lines, etc. After curing, even if it encounters high temperature, 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 silica gel has become an indispensable material in the manufacturing process of electronic appliances, automobiles, instruments, high-temperature kitchen appliances and other fields. Yantai chemical RTV silica gel has high and low temperature resistance, weather resistance, aging resistance and other formulas. If the demand is large, you can Buy in bulk, just pay attention to storage. Yantai Chemical has been deeply involved in the electronic adhesive industry for more than ten years.
