For processing wood and structures, various anti -piren compounds are used from it. One of the latest developments of scientists is a fireproof coating that allows protecting wooden structures not only from fire, but also from damage by various microorganisms, insects, etc. Among other advantages of this coating, environmental friendliness and safety for people and animals should be noted, as well as the uniformity of the composition close to wood, and the absence of a surface film after impregnation of structures. Anti -piren compounds can be both colorless and staining the surface in fairly attractive shades. They can be used not only for wooden structures, but also for processing materials such as chipboard, fiberboard, plywood.
