ENHANCING THE ENVIRONMENTAL CONDITIONS IN EDIFCES AND CONSTRUCTIONS BY THE APPLICATION OF BIO-RESISTANT COATINGS

Microscopic organisms pose a significant threat to various structural materials such as wood, metal, and reinforced concrete. Their proliferation contributes to the emergence of technogenic mycoses, mycotoxicoses, and microallergoses, which negatively affect human health and environmental quality. This study aims to develop optimized formulations of protective coatings with enhanced bio-resistance for application in building structures. Using epoxy binders, fungicidal additives, finely dispersed fillers, and a range of pigments, we designed and tested thick-layer coatings. A mathematical experimental design was employed to identify optimal component proportions. The coatings were evaluated for fungal resistance using standard techniques (GOST 9.049-91). Results revealed that all samples exhibited varying levels of microbial contamination, leading to reductions in strength and elasticity. However, the incorporation of biocidal agents, particularly copper sulfate, significantly improved the biological stability of the coatings. These findings support the application of biocidal-enhanced coatings to prolong structural durability and promote healthier built environments.
