A rapid test method of evaluation of durability of coatings made from powdered paints
The durability of coatings made of powdered polyether paints has been defined with a rapid test method for the first time. The method is based on the empirical exponential dependence of coating life on the energy of activation of the thermal-oxidative breakdown of paint film-forming material. Quantitative estimation of the influence of the basic destructive factors during the use of coatings on their durability has been made. The rapid test method reduces significantly the period of certification of powdered paints in terms of «durability». It also reduces the period of introduction of powdered paints in order to obtain the metal, concrete, slate, plaster coatings.
