PROCESS TO PREPARE LOW TEMPERATURE CURABLE WATERBORNE POLYURETHANE COATINGS
摘要
<p>The invention relates to a process to prepare ambient curable waterborne polyurethane coatings by which the isocyanate and the polyols are mixed thoroughly before their emulsification in water, by low shear mixing at room temperature. The polyol resins composition suitable for the present invention are polyacrylate resins having a hydroxyl value of from 60 to 180 mg of KOH/g of solids, an acid value of from 10 to 30 mg of KOH/g of solids, and a calculated glass transition temperature of from -40°C to +65°C.</p>
