Is RTV silicone different than regular silicone?

The key difference between RTV and silicone is that RTV is a general term for room temperature vulcanizing silicone, whereas silicone is a polymer material having repeating units of siloxane. However, normal silicone is a low-cost product, so many people use silicone over RTV.

What is 100\% silicone used for?

100\% silicone caulk is used where you would find water. Where water can sit or hit. Some perfect examples where you would want to use this type of silicone caulk sealant is silicone caulking bathtub, silicone caulking shower, shower head and handles area, and behind fittings.

What does RTV mean in silicone?

Room Temperature Vulcanization
An RTV (Room Temperature Vulcanization) silicone sealant is a sealant that begins to cure immediately upon being exposed to air (specifically the moisture present in the air), as opposed to water-based sealants such latex.

What is RTV silicone good for?

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.
