Sealing Materials Based on Polymers

Abstract

Polymer-based sealing materials currently play a large and important role in almost all areas of industry. The use of sealants can increase the energy saving of building structures, the safety of vehicles, etc. Sealants are equally used in such specialized applications as the aerospace field, and are also used to solve everyday problems, such as sealing plumbing. The main consumption of sealants is in construction and automotive. This review provides data on the global and domestic market for sealing materials; The basic terms and definitions used in the field of adhesive and sealing materials are analyzed. The main differences between the terms adhesive and sealant are discussed. The classification of sealants is given in accordance with modern international regulatory documents. It is disassembled that they are one-component reactive hot-melt sealants. Their main advantages and disadvantages are listed. It is noted that the development of the industry of sealing materials is likely to move towards the development of moisture-curing compositions based on silane-modified polymers. This assumption is supported by a fairly detailed classification of silane-modified polymers in the FEICA classification guide for sealants and adhesives.
