Abstract:
A method for the surface coating of metal parts comprising applying a solvent-free, two-component, controlled adhesion strippable coating for metal surfaces comprising components A and Bwherein component A comprisesfrom 5 to 20% by weight of an optionally substituted aromatic diamine;from 0.1 to 5% by weight of a dehydrator;from 0.01 to 1% by weight of an accelerator based on tertiary amines;from 0.01 to 1% by weight of an accelerator based on organic tin compounds; and a polyether polyol based on poly(oxyalkylene) glycols,and wherein component B comprises from 40 to 60% by weight of an aromatic diisocyanate based on a phenylene or toluylene diisocyanate, andfrom 40 to 60% by weight of a polyether polyol based poly(oxyalkylene)glycol to a metal surface to be protected; wherein the curing time is less than 30 minutes and the curing temperature is between 10 and 40.degree.
