Abstract

Polyurethane coatings are produced in situ on substrates such as metal, rubber, paper, leather and fabrics by applying consecutively thereto at least one polyester or polyesteramide component and at least one polyisocyanate, the polyester or polyesteramide component being applied in the form of an aqueous dispersion free from any soap or dispersing agent other than alkali. The dispersion may also contain a pigment, e.g. titanium dioxide, carbon black or an organic pigment. The polyester or polyesteramide may be partially pre-reacted with a polyisocyanate. The coatings may be cured by immersion in di-isocyanate solutions followed by heating to 100 DEG C; curing can also take place at room temperature. In examples a diisocyanate -modified polyester amide is prepared from the reaction product of adipic acid, ethylene glycol and monoethanolamine, and hexamethylene diisocyanate; this is applied in an aqueous dispersion to rubber strips and followed by diphenylmethane-4, 41-di-isocyanate.ALSO:Substrates are coated with polyurethanes by applying consecutively at least one polyester or polyesteramide and at least one polyisocyanate, the polyester or polyesteramide being applied in the form of an aqueous dispersion free from any soap or dispersing agent, exceptting alkali. The polyester or polyesteramide may be partially pre-reacted with a polyisocyanate. The aqueous dispersion may be applied by spreading, dipping or spraying. The polyisocyanate may be applied in a similar fashion as a solution or dispersion in an inert organic solvent. The substrate may finally be heated or may be left to cure at room temperature. Substrates which may be coated include natural and synthetic rubber, fabrics including polyethylene terephthalate and nylon, leather, paper, and metals.
