Product Name: HS-1520 Unsaturated Polyester Resin
1. Brief Introduction:HS-1520 is a cutting-edge NPGl type unsaturated polyester resin specially designed for SMC and BMC applications. Boasting high reactivity,
low viscosity, and superior coloring and thickening properties, this resin ensures a flat surface with exceptionally high gloss. It offers outstanding water and heat resistance, remarkable mechanical strength, and excellent electrical performance. Ideal for use in electrical parts, industrial components, sanitary ware, and vehicle parts, as well as various other fields.

Note:
1) The method for making the cured product follows GB/T 8237 standards. Curing system: 0.6% Co-Naph, 1.5%,
AKZO M-50: 1.5%;
2) Post-cure process: room temperature for 24 hours followed by 60ºC for 3 hours and 110ºC for 2 hours.
4. Storage:
Store the product in a cool place under 25 ºC, away from open flames, heat sources,and ensure it is sealed to prevent exposure to moisture, monomers, and volatile substances. For prolonged storage at ambient temperature of 25 ºC, the shelf life extends up to 6 months.
