Agent for the surface treatment of flat insulating materials

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 <IMAGE> 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.
