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 translation: 用于在工业辊上形成聚氨酯涂层的方法包括将包含预聚物组分和固化组分的涂层形成反应混合物的产物的涂层施加到工业辊上。 预聚物组分包括聚碳酸酯预聚物，其是预聚物形成反应混合物的产物，其包含异氰酸酯组分和聚碳酸酯多元醇，并且预聚物组分以30重量％至80重量％的量存在于涂料形成反应混合物中 ％，基于涂料形成反应混合物的总重量。 固化剂组分包括氯化芳族二胺固化剂，并且固化组分以涂料形成反应混合物的总重量计为5重量％至20重量％的量存在于涂料形成反应混合物中。 此外，涂层被固化以在工业辊上形成聚氨酯涂层。
