Summary: | A urethane composition useful in a variety of applications such as, for example, as a direct-to-metal coating, i.e. a coating composition that can be applied directly to the surface of a metal substrate without a primer or pretreatment is described. The coating composition preferably includes a polyol that is the reaction product of a resin of general formula (I) with an acid or a diol respectively, with the reaction being carried out in the presence of a catalyst. The coating composition also includes an isocyanate-functional compound as a crosslinker. The coating composition forms a corrosion-resistant film when applied directly to the substrate surface without a pretreatment or primer. |
