What feature distinguishes Type S sealants?

Type S sealants are characterized by a single-component formulation, which means they come ready to use and do not require mixing with other components before application. This makes them convenient for users, as they do not need to measure and mix different substances, thus reducing the chances of errors during preparation.

Single-component sealants also tend to cure through evaporation of solvents or through exposure to moisture in the air, which can simplify the application process. The user simply needs to apply the sealant directly to the surface, and the curing process begins automatically.

In contrast, multi-component sealants require precise mixing and are often used in applications where enhanced performance characteristics, such as chemical resistance or extreme durability, are needed. Self-leveling properties refer to a particular type of sealant that flows easily to fill gaps but does not apply specifically to the characteristic of Type S sealants. Non-sagging ability is important in construction and tiling, especially in vertical applications, but is not a defining trait of Type S sealants, which are primarily recognized for their single-component nature.
