What is Silicone Sealant?

Silicones are synthetic polymers composed of silicon, oxygen, carbon, and hydrogen.

They are the most common type of sealant and are very popular in construction applications. Typical silicone sealants are temperature-resistant up to 250°C. Silicone sealants generally have a low viscosity, meaning they can be easily applied with a caulking gun without requiring any special tools or techniques.

The low viscosity of silicone sealants also makes it easy for even novice users to achieve good results. Experienced users will find MS polymer sealants no more challenging to apply.
