THE INFLUENCE OF PAINT AND VANISH COATING CHARACTERISTICS ON THEIR FLAME-RETARDANT AND OPERATIONAL PROPERTIES AND SCOPE OF APPLICATION

The flame-retardant effectiveness of paint and varnish coatings depends not only on their composition and flame-retardant properties, but also on the operational characteristics that determine the service life and quality of coatings. Standard test methods for modern building paints do not include an assessment of adhesion resistance and strength when evaluating the effectiveness of protection of wood and metal elements of buildings and structures as a mandatory element.
In this work, a comprehensive study of paint coatings is carried out, which, according to the characteristics stated by the manufacturer, have the first group of fire protection for wood and metal, including an assessment of their adhesive properties and hardness, according to standard test methods to standard methods of state standards. It is found that applying paint to wood increases the smoke generation of the material thus protected. At the same time, paint and varnish coatings exhibit good performance properties, which allows them to be used as decorative for painting wet facades and fences. The data obtained in the study can be used in the development of fire protection measures, as well as taken into account in the development of recommendations for the application of paintwork.
