ABSTRACT:
The invention relates to coating compositions for producing watertight, vapor-permeable and flame-retardant coatings, comprising a vinyl chloride copolymer or vinyl acetate/ethylene dispersion, flameproofing agents, foam stabilizer and optionally crosslinkers. The invention further relates to a process for producing watertight, vapor-permeable and flame-retardant coatings by mechanically foaming the coating composition to produce a stable foam, applying the foam to a woven, knitted or nonwoven support material on one or both of the sides and drying it at a temperature of from 60.degree. to 180.degree. C. and optionally, after drying, compressing the foam layer. The textile support materials coated with the coating composition are suitable for use in building protection and in the geotextile sector.
