Corimax Red 2030H is a high performance pigment, middle opacity, with outstanding fastness properties. It is recommended for all application.


Recommended for automotive paints, architectural coatings, coil coatings, industrial paints, powder coatings, printing pastes, PVC, rubber, PS, PP, PE, PU, offset inks, water-based inks, solvent inks, UV inks.

पिगमेंट रेड 254 is neutral red, has excellent solvent resistance, and has a light fastness of 8 grades. It is mainly used in automobile primer. Its flocculation can be improved by adding additives. In order to reduce costs, it can be mixed with CI वर्णक लाल 170, which has stronger blue light but lower light resistance. Transparent blue light red; also widely used in plastic (PVC, PS, polyolefin, etc.) coloring, in HDPE (1 / 3SD) heat stability of 300 ° C / 5min.

आणविक संरचना:

Synthetic principle: Sodium metal and a small amount of penetrant OT are added to tert-amyl alcohol. Nitrogen is added, the temperature is increased to 100-150 ° C, and the metal sodium is completely dissolved to prepare sodium tert-amyl alcohol; , Diisopropyl succinate (or diethyl succinate) was slowly added at 110 ° C to stir the reaction, tert-amyl alcohol was distilled off, filtered, washed with water, and dried to obtain a crude product; and then added to a sodium hydroxide solution at 70-80 ° C Stir, filter, and wash with water to obtain the product.
