  • Patent number: 6207225
    Abstract: A solvent-free, two-component strip coating for metal surfaces is described which comprises the following components: A) 5 to 20% by weight of an optionally substituted aromatic diamine, 0.1 to 5% by weight of a dehydrator, 0.01 to 1% by weight of an accelerator based on tertiary amines, 0.01 to 1% by weight of an accelerator based on organic tin compounds, a polyether polyol based on poly(oxyalkylene) glycols as the remainder; B) 40 to 60% by weight of an aromatic diisocyanate based on a phenylene or toluylene diisocyanate, 40 to 60% by weight of a polyether polyol based (poly(oxyalkeylene) glycols. Despite its freedom from solvents, the strip coating according to the invention has rapid-hardening and rapid-drying properties, can be applied to a metal surface to be treated in a single spray operation and finally can be removed without problem and residue-free.
