CURATIVE AGENT FOR COATINGS ON INDUSTRIAL ROLLERS |
摘要 |
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. |
