Abstract

The properties of paint coatings under the influence of standard test cultures and microscopic fungi isolated under natural conditions of a temperate (Moscow) and moderately warm climate (Gelendzhik) were studied. Changes in the decorative properties of coatings VE-69 and EP-140 after exposure to individual strains of micromycetes were revealed. It is shown that the color change of VE-69 and EP-140 coatings with red pigment is higher than for coatings of similar enamels with gray pigment. The study of adhesive properties did not reveal any changes on all samples, both after standard tests with test cultures according to GOST 9.049–91, and after long-term (45 and 90 days) exposure to monocultures of micromycetes isolated in temperate and moderately warm climates.
