    Features & Benefits

    Features

    copper chromium is a black pigment with blue phase, the color is pure, the blackness is also better, the cover force is also very good. the metal content in copper chromium is high, so the weight of pigment particles is large, and it is necessary to prevent it from settling due to excessive specific gravity when used in paint systems.
    copper chromium is also suitable for a wide range of resin and polymer systems, common coating resin systems can be used.
    copper chromium has stable performance and good outdoor durability, and although its coloring performance is not as good as that of carbon black products, it is still widely used in a variety of high-grade coatings and engineering plastics.
    copper chromium is a spinel type, in which copper, chromium and other elemental ions through high temperature solidification should be firmly bound to the lattice, the human body and the environment is non-toxic, can be regarded as non-toxic pigments.
