AHA1053

Description

AHA1053 is a wax additive used in metallic effect powder coatings during bonding processing. The use of this product will be able to help orientation of metallic pigments, improve flip-flop effect and increase T_g of final coating powders as well as decrease dosages of these precious metallic pigments, esp. aluminum powder.

Application

AHA1053,as an orientating agent of metallic pigments, is widely suitable to all typical powder coatings like as hybrid, TGIC and so on. However, it is specially recommended to use in bonding processing in order to increase bonding efficiency, improve brilliance/luster and strengthen flip-flop effect as well as decrease dosages of these precious metallic pigments.

Advantages:

• Facilitate to metallic pigments orientation
• Enhanced processing temperature during bonding process
• Improved flip-flop effects on metallic-like film surface
• Reduced dosages of metallic pigments
• Increased heat and humidity resistance and salt spray

To adjust the use levels and fineness of product may strengthen and achieve the optimization, it is necessary to carry out laboratory test for each specific application. In principle, higher dosage and less fineness may affect dramatically metallic brilliance uniformity at different viewing angles, but such influence is too complex for us to be able to give detailed recommendations here.

Incorporation

AHA1052 is added to the binder/ingredients blend before extrusion, then melthomogenizing to form base powder, then dry blending metallic pigments to above base powder under low shear conditions.
