VERWENDUNG VON STICKSTOFFVERBINDUNGEN ZUR OBERFLAECHENBEHANDLUNG VON FLAECHENISOLIERSTOFFEN.

摘要

The invention relates to agents for the surface treatment of flat insulating materials having a base of aromatic polyamides, and to a method for improving the surface characteristics of such flat insulating materials. According to the invention, such agents have the structure where at least one of the radicals R1 to R3 has a reactive group which can be incorporated into an impregnating resin system. Advantageously at least one of the radicals R1 to R3 has a reactive hydrogen atom or has an ethylenic or acetylenic unsaturated grouping.
