RTV Silicone FAQs

What is RTV silicone used for?

RTV silicone is used for adhesive sealing, electronic encapsulation, and moulding applications. Common uses include bonding and sealing components, protecting electronics from moisture and contaminants, and producing flexible rubber parts and tooling.

What should I consider when choosing an RTV silicone for electronic encapsulation?

For encapsulation applications, key selection factors include cure system, viscosity, operating temperature range, and - for two-part products - pot life and working time.

How do I select the right RTV silicone product?

Start by identifying the application; adhesive sealing, encapsulation, or moulding. From there, consider the cure system, operating temperature range, and whether a one-part or two-part formulation is required.
