It is a kind of colored powder, it\s quality is stable with fine decentralization, strong tinting strength.
We have full types including sores of red, yellow,blue,green,brown, black. It is widly used for concrete products(roof tiles, pavement, block, pavers, brick and tiles, paints and coatings, plastic and rubber), ceramics, asphalt pavement and so on.
