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.

Abstract: A process for producing a polyurethane-coated conduit element includes mixing a) a mixture of aromatic and aliphatic polyisocyanate with, b) at least one polymeric compound having at least two hydrogen atoms which are reactive toward isocyanate, c) at least one chain extender, d) a catalyst, and e) optionally at least one other auxiliary, additive, or both, to form a reaction mixture; applying the reaction mixture to a conduit element; and allowing the reaction mixture to react to form a polyurethane layer. The polyurethane-coating conduit element is suitable for maritime applications in the oil and gas industry, which polyurethane has improved hydrolysis stability at high temperatures and nevertheless satisfies the high mechanical demands in the oil and gas industry.
