        ? Excellent leveling and smoothness. 
        ? Excellent weather resistance.
        ?
        3. Use method & levels
        ? Equivalent weight of this product is approx 275. It is recommended to cure with hydroxyl polymer in equivalent amount (13:87 for polyester with hydroxyl value of 30; 20:80 for polyester with hydroxyl value of 50). Tin-based catalysts can significantly improve coating mechanical properties and solvent resistance..
        ? Unsealing temperature of this product is above 170℃, so it is recommended to fully cure at 180℃*20min or 200℃*15min. 
         
        4. Package & Storage
