FAQ:

Q: What does RTV silicone mean?

A: RTV Silicone (Room-Temperature- Vulcanizing silicone) is a type of silicone rubber made from a two-component system (base plus curative; A+B) available in a hardness range of very soft to medium–usually from 15 to 40 Shore A . RTV silicones can be cured with a catalyst consisting of either platinum or a tin compound such as dibutyltin dilaurate.

Q: What is RTV adhesive?

A: RTV silicone adhesive is a ready-to-use sealant that can resist weathering and chemicals, often used for electrical insulation. The adhesive is often applied to surfaces when pourable sealant cannot be used.

Q: Is RTV silicone electrically conductive?

At room temperature, the electrically conductive silicone adhesive has a work time of 15 minutes, a tack-free time of 60 minutes and a cure time of 72 hours.
