Silicone sealant or adhesive is a powerful, flexible product that can be used in many different applications. Although silicone sealant is not as strong as some sealants or adhesives, silicone sealant remains very flexible, even once it has fully dried or cured. Silicone sealant can also withstand very high temperatures, making it ideal for applications that suffer high heat exposure, such as on engine gaskets.
Silicone sealants come in a variety of different forms. For example, one way to buy silicone sealant is in a two-component addition; this type of product requires the user to mix two compounds to make the sealant. The mixture must be made immediately before using it, which makes this type of silicone sealant rather tricky to use.
