Sealants, eventually lose

However, distinguishing them from cheaper sealants is difficult. The content of various filler additives worsen the properties of the sealant. Three types of filler are added to silicones: organics extensers, mechanical, such as quartz or glass flour, chalk, as well as organic solvents. The presence in silicone sealants of a relatively small amount (up to 10%) of organic extensions slightly affect its qualities. But they do work with the material more convenient, and also simplify further care. This group includes all sanitary sealants used in kitchens, bathrooms, toilets, as well as in rooms with high humidity. They also introduce a fungicide that prevents the formation of black mold with mildu. However, the organic component does not tolerate ultraviolet, so it is not recommended to use in external work. Extensive resins — other types of additives used in silicone sealants, eventually lose mechanical strength. In Russia, they are often used for the manufacture of double -glazed windows.
