    Abstract: A system for forming an elastomeric composition for application to a substrate includes an isocyanate component and an isocyanate-reactive component. The isocyanate component includes a polymeric polyisocyanate and optionally an isocyanate-terminated prepolymer. The isocyanate-reactive component is reactive with the isocyanate component and includes a polyol component and a polyetheramine. The polyol component is a mixture of (a) a hydrophobic polyol; (b) a polyether polyol different than the hydrophobic polyol and having a weight average molecular weight greater than 500 g/mol; and (c) a polyaminopolyol. The elastomeric composition is formed as the reaction product of the isocyanate component and the isocyanate-reactive component and may be applied as an elastomeric coating layer on a substrate such as a steel pipe. The steel pipe having the applied elastomeric coating layer satisfies the standard for use in the water supply industry as set forth in AWWA C222.
