INFLUENCE OF PAINT COATING THICKNESS ON THE PROBABILITY OF CRACKING

Abstract

The paper investigates the probability of cracking for polyvinyl acetate-cement coatings depending on their thickness and strength of adhesion to the cement substrate. Data on changes in the cohesive strength of paint coatings depending on their thickness is provided. A model is proposed for changing the cohesive strength of the coating depending on the thickness. A statistical assessment of the probability of destruction is conducted to examine cracking. A graphical model of the probability of cohesive failure depending on the thickness and adhesion strength of coatings is proposed.
