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.

A composite includes a first preform and a second preform spaced from and in overlying relationship to the first preform. The second preform defines at least one first opening extending therethrough along an axis transverse to the first preform. A first surface layer is disposed adjacent to the second preform and on an opposite side of the second preform from the first preform. A polymeric composition including the reaction product of an isocyanate component and an isocyanate-reactive component is disposed between the first preform and the second preform. The polymeric composition adheres the first surface layer to the second preform through the at least one first opening. The surface layer is adhered to the second preform during molding of the composite article and in the absence of additional adhesive, thereby reducing production time and cost of the composite article.

An appliance includes a housing having top and bottom panels disposed opposite each other and a plurality of walls connected to the top and bottom panels. The top and bottom panels and the plurality of walls define a cavity of the appliance. The housing also has an outermost surface about which a polyurethane foam is disposed. The polyurethane foam reduces noise and vibrations emitted from the appliance during use and has a density of from 20 to 50 pounds per cubic foot (pcf). The polyurethane foam also has a damping factor of at least 0.2 measured at a temperature of from 40&#xb0; C. to 60&#xb0; C. Furthermore, the polyurethane foam has a k-factor of less than 2.0 btu-in/hr-ft-&#xb0; F. which reduces an amount of energy required to operate the appliance. The appliance is formed by applying the polyurethane foam to at least one of the top panel, bottom panel, and plurality of walls.
