What Are the Specific Applications and Precautions of RTV Silicone Rubber?

RTV silicone (room temperature vulcanizing silicone rubber) is a milky white viscous liquid composed of silicone rubber, crosslinking agents, and fillers. RTV silicone rubber is a solvent-free, non-corrosive single-component room temperature vulcanizing silicone rubber. It has a long storage period, stable performance, and can bond common metal and non-metal materials. Therefore, it is suitable for bonding and sealing between various metals, as well as between metals and non-metal materials.

The Role of RTV Silicone Rubber

A single-component RTV silicone rubber can be directly applied to electrical metal, not only achieving the effect of bonding and fixing components but also providing insulation performance. It can enhance the insulation index of electrical appliances. Major brands have good guarantees in this area, focusing on research on RTV silicone rubber and providing customized solutions for RTV silicone rubber applications. If used in communication equipment or instruments, it can also be used as a sealing material with good moisture-proof performance after curing.

In fact, both single-component and two-component RTV silicone rubber can be used in electrical manufacturing, and the performance is guaranteed to be safe after curing. Although some alcohol odor may be released during the curing process, it will not affect the health of construction personnel. After curing, they do not contain alcohol and have no toxic side effects.

Although single-component RTV silicone rubber is safe to use in electrical manufacturing, attention should be paid to the construction method, otherwise, it will lower the overall quality of the electrical appliance. When injecting glue, pay attention to the thickness of the glue, and it is not recommended to exceed 3mm, otherwise it will affect the time required for overall curing. If necessary, layered pouring can be adopted, which will not prolong the time required for curing.

Precautions for Using RTV Silicone Rubber

If the next construction is carried out before the RTV silicone rubber is completely cured, component movement during the construction process will result in unstable bonding and performance loss, which is meaningless.

RTV room temperature vulcanizing has temperature resistance, but the temperature cannot exceed 200 degrees. Otherwise, the performance will change or even delamination may occur at high temperatures. If the ambient temperature is high, it is recommended to purchase adhesives specifically designed for high-temperature resistance, which will be safer.

Whether it is a single-component or two-component product, users of RTV silicone moulding rubber need to strictly control the construction steps. If cracking or incomplete sealing occurs, it is necessary to pour another layer of glue.

As a silane bonding, sealing, insulation, moisture-proof, and shock-proof material, RTV silicone moulding rubber (room temperature vulcanizing silicone rubber) is widely used in bonding and sealing of electronic components, semiconductor materials, electronic devices, waterproofing and sealing of electric heating appliances and electronic instruments, and potting of electronic components, such as sealing the end of an electric heating appliance, bonding magnets and metal shells of small motors, bonding and sealing car lights, optical instruments and lenses, bonding electronic instrument shells, insulating protection for motors, bonding and sealing electronic components, and so on.
