The main task, which the sealing substances should perform, is to ensure the complete impermeability of joints, seams, compounds from moisture and air penetration. Also, sealants are used to process double -glazed windows, in order to avoid noise penetration. Hermetic substances are very resistant to the widest temperature range, have excellent elasticity. Any sealing substance is based on special mastic, which, when exposed to the external environment or special chemicals, will acquire the necessary hardness. Sealants have a whole healthy properties, such as high resistance to moisture penetration, excellent clutching functions, greater mechanical strength. They are perfectly connected to different types of surfaces, including stone, concrete, metal, plastic, ceramic and other types of surface. With the correct implementation of technological processes, the sealing substance will perfectly provide connective properties with such surfaces. The sealing substances are currently distinguished according to the basis of their manufacture. These are sealants on Uretanova, Tiocol, Silicon, Acrylic and other types of basics. They are also divided by readiness for instant use. There are one thing – and multicomponent sealants. If one -component can be used without accepting any additional actions, then the multicomponent requires careful dosing and mixing the components.

Over some time, hardening sealants acquire an elastic texture and become similar to rubber. Sealants that do not have this property remain plastic. There is also a sealing substance that dries after application, maintaining a certain share of elasticity. The most universal sealing substance that has become most widespread is a silicone -based sealant. They are extremely easy to use, have an affordable cost, a high degree of reliability. They are used to eliminate small holes and cracks, the polyurethane group of sealants is effective in sealing flexible compounds. Tiocol sealants are highly resistant to various types of solvents.
