FIELD: process engineering. ^ SUBSTANCE: proposed invention relates to p.c.b. protective coats produced by applying epoxy-urethane or epoxy lacquer or organic silicon compound-based lacquer on p.c.b. surface and drying it. It differs from known methods in that, to add biological resistance after heating, biocide additive Biocice T is introduced in lacquer composition in the ratio that follows, i.e. content of epoxy-urethane or epoxy lacquer or organic silicon compound-based lacquer makes (98.5 to 99.5) wt %, and biocide additive makes (0.5 to 1.5) wt %. ^ EFFECT: improved operating performances. ^ 1 cl, 2 ex |
