| Usage:： |
Product formulations grade , red blue red close ε-CuPc , excellent light fastness, weather , high transparency and solvent fastness , Cromophtal Blue A3R specific surface area of 40m2 / g.
For automotive coatings and other metal decorative paints , and even light than CuPc; dilute the color is still in excellent durability , but lower than α- type CuPc color strength is lower ;
also used for coloring plastics , thermal stability of polyolefin 300 ℃ / 5min (HDPE sample 1/3SD color difference ΔE just under 300,200 ℃ handled 1.5 ) ; flexible PVC excellent resistance to migration, light fastness of 8 (1/3SD);
also used Mint grade ink .
Mainly for the automotive original finish. |
