FIELD: technological processes.
SUBSTANCE: invention relates to production of foil-coated glass textolites used for production of printed circuit boards (PCB). Lined with one or two sides with metal foil glass textolite is made by pressing of foil and glass fabric. Glass fabric is impregnated with epoxy composition. Composition contains epoxy Diane resin, 4,4′-diaminodiphenylsulfone, nickel acetylacetonate, organosilicon titanium compound and filler submicron size powder of spherical particles of copolymer of butadiene, acrylonitrile, styrene, methacrylic acid. Invention increases stability of linear dimensions of glass-cloth laminate to 0.01 %.
EFFECT: high stability of casting dimensions.
