    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 wood composite article includes a plurality of wood pieces and an adhesive system disposed on or dispersed among the plurality of wood pieces for bonding the plurality of wood pieces. The adhesive system includes a binder component and a fiber component. The binder component comprises a thermosetting plastic component such as unsaturated polyesters, epoxy, polyurea, polyurethane or combinations thereof, including for example, an isocyanate compound and an isocyanate-reactive component. The composite article may be formed into various objects such as railroad ties, fencing and the like.
