          2.Characteristics

          l Extremely high crosslink density , excellent surface hardness and chemical resistance for coating .

          l Excellent leveling and smoothness.

          l Excellent weather resistance and anti yellowing performance.

           

          3.Use method & levels

          Equivalent weight of this product is approx 310. It is recommended to cure with hydroxyl polymer in equivalent amount (15:85 for polyester with hydroxyl value of 30; 22:78 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
