Abstract: A method for forming a polyurethane coating on an industrial roller includes applying a coating that is a product of a coating forming reaction mixture, which includes a prepolymer component and a curative component, to an industrial roller. The prepolymer component includes a polycarbonate prepolymer, which is a product of a prepolymer forming reaction mixture that includes an isocyanate component and a polycarbonate polyol, and the prepolymer component is present in the coating forming reaction mixture in an amount from 30 wt % to 80 wt %, based on a total weight of the coating forming reaction mixture. The curative component includes a chlorinated aromatic diamine curative agent, and the curative component is present in the coating forming reaction mixture in an amount from 5 wt % to 20 wt %, based on the total weight of the coating forming reaction mixture. Further, the coating is cured to form a polyurethane coating layer on the industrial roller.

Abstract: A two-component curable adhesive or sealant composition is provided. The first component may comprise a mixture of at least one polyol selected from the group comprising a polyester polyol, a polyester-polycarbonate copolymer polyol, and combinations thereof, a resin, and optionally a solvent. The second component may comprise a prepolymer obtained by reacting a polyester-polycarbonate copolymer polyol which is the reaction product of a polyester polyol which is the reaction product of one or more organic acids, and one or more glycols having a functionality of two or more and one or more polycarbonate polyols, at least one organic polyisocyanate component, and at least one chain extending agent and optionally a solvent. Alternatively, the first component may comprise a polyester-polycarbonate copolymer polyol, a resin, and optionally a solvent. The second component may comprise a polyisocyanate curative and optionally a solvent. The cured adhesive exhibits improved hydrolytic properties while maintaining excellent processability and adhesive properties.
