Abstract

In this work the analysis of experience of application of different approaches for achievement of necessary characteristics of coatings on the basis of epoxy film-forming at the expense of component modification of film-forming system is carried out. Ways of modification of hardeners for epoxy film-forming and epoxy resins are considered, influence of modifying agents on properties of coatings is described. The great attention is given in particular to amine hardeners, as to the most widespread hardeners of epoxies. Among modifiers of epoxy oligomers for receiving coatings uretan-containing, organic silicon oligomer products and rubbers are allocated.
