Abstract

A lacquer suitable for the preparation of polyurethane surface coatings comprises an organic polyisocyanate, an inert organic solvent and a polyether which contains two or more -OH groups and two tertiary amino groups of which the nitrogen atoms are each directly attached to an otherwise unsubstituted benzene ring in meta position to each other. Water in amount 0.5 to 10% of the weight of the polyether may also be incorporated. In the example, m-phenylene diamine was reacted with 1:2-propylene oxide and the resulting polyether mixed with urea-formaldehyde resin, cyclohexanone and methylisobutylketone, water and an xylene solution of the phosgenation product of crude diaminodiphenylmethane containing about 15% of polyamines prepared by condensing HCHO with aniline in the presence of HCl. The lacquer so obtained was used as a coating for steel.ALSO:A lacquer suitable for the preparation of polyurethane surface coatings comprises an organic polyisocyanate, a hydroxyl containing polyether containing two tertiary amino groups of which the nitrogen atoms are each directly attached to an otherwise unsubstituted benzene ring in meta position to each other and an inert organic solvent. In the example a mixture of propoxylated m phenylene diamine, urea-formaldehyde resin, cyclohexanone and methylisobutylketone, water and a xylene solution of polyisocyanate was formed and used to coat steel.
