Polyaspartic Anti-corrosive topcoat

Item No.: PH9503
PH9503 polyaspartic coating is a relatively new class of coatings that have been used successfully in a number of high profile protective applications for various steel structures.
Description
PH9503 is composed of Polyaspartic esters and various anti-corrosive pigments and fillers,additive and a small amount of solvent. All main ingredients are manufactured by own.
Characteristic
  • Excellent weather resistance and gloss retention
  • Good adhesion to substrate
  • Excellent impact resistance and wear resistance
  • Quick drying
  • High solid content
Application:It can be used as a weather-resistant finish for various steel structures, fiberglass and various decorative materials.
