FIELD: chemistry.
SUBSTANCE: coating contains cross-linked binding system which forms three-dimensional nets when thermally hardened. After application of coating on the rear side of fibrous base and hardening coating is capable of hygroscopic expansion, which gives excellent anti-sagging properties. Coating is compatible with other coating systems with neutral or weak alkali pH. Binding system is neutralised by water ammonia solution, which quickly evaporates not to interfere with reaction of cross-linking.
EFFECT: creation of improved fibrous base with coating, which is biologically safe, is stable to sagging and simultaneously preserves high resilience modulus, is compatible with other coatings and fillers and makes it possible to prevent corrosion of technological equipment.
