Abstract

In this work the main attention has been given to choice of recipe of inhibitive pigments and fillers, and also definition of their optimum ratio in the polymeric film-forming. For researches the epoxy compositions modified by liquid polysulphide rubber, containing inhibitive pigments and fillers of different structure have been used. For curing of primer compositions organic silicon ammine has been used. For acceleration of process of curing of primer compositions, it was used tertiary amine UP-606/2. As a part of pigmental composition the inhibitive pigments as well as structure-forming fillers, have been investigated.
