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.

Abstract: Provided herein are novel and improved weight coating systems suitable for use with pipes, particularly pipes that are submerged in liquid, such as water, in environments including oceans, seas, marshes, lakes and rivers. The novel coating systems provided herein comprise an aggregate and a polyurethane binder, wherein the polyurethane binder is a two-component composition comprising an isocyanate component and an iso-cyanate-reactive component. The coating systems provided have increased durability, as well as flexibility allowing for efficiencies related to transportation, storage, use and resistance to corrosive effects. Furthermore, the coating systems are cost effective and have minimal or zero impact on the environments in which they are utilized.
