Anti Yellowing Agent (ACS-525)
ACS - 525 is the polymer materials which is used in all kinds of powder coatings to prevent the coating from yellowing because of high temperature oxidation or long term air oxidation and improve the weathering resistance of outdoor powder coating. ACS-525 is complex product screened out through several experiments. Each component works together and achives the best optimum effect.
