How is rtv silicone rubber cured? What about the construction steps?


RTV silicone rubber is often used in the fields of electrical appliances and electronics, and computers are also used in the manufacturing process. Due to the high usage rate, some users are more concerned about the curing problem. Understanding the curing process and construction steps can better enable the performance of rtv silicone rubber.

Curing of rtv silicone rubber:

RTV silicone rubber is a room temperature vulcanized silicone rubber, which is divided into one-component and two-component adhesives. The one-component curing method is relatively simple. It only needs to be exposed to water vapor in the air to cause a curing reaction, and it can be completely cured after 24 hours. The two-component rtv silicone rubber will only undergo a curing reaction when the AB component is evenly stirred and applied to the substrate. It has the characteristics of deep vulcanization and is elastic after curing. Electronic components will not be easily bumped in turbulence.

What are the construction steps of rtv silicone rubber?

When constructing one-component rtv silicone rubber, you first need to ensure that the surface of the substrate is clean, and then squeeze out some glue on the position that needs to be applied. Large-sized ones can be used with a dispenser, and small-sized ones can be used directly by hand. Squeeze out the glue. Commonly used in the bonding and fixing of electronic components.

Before the curing reaction occurs, the position of the electrical components coated with glue can be adjusted at will. Once the curing reaction occurs, it cannot be adjusted again to prevent the occurrence of poor bonding strength after curing.

The construction of two-component rtv silicone rubber is cumbersome. It is necessary to weigh the two components of A and B and stir them separately. After stirring evenly, it can be applied to the substrate, and it is usually used in the reproduction and manufacture of electronic appliances and mechanical parts.

RTV silicone rubber is suitable for use in electrical appliances with high safety index requirements, because it can achieve flame retardancy and high thermal conductivity after curing, preventing electrical appliances from burning due to high temperature during use, and can also be used in high-power electrical appliances, chargers. Because of the wide range of applications, you must look for branded products when purchasing. They have a wide range of uses and can be used in new energy, military, medical, aviation, shipping, electronics, automobiles, instruments, power supplies, high-speed rail and other industries.
