Application

1. In the building materials industry, it is mainly used for colored cement, colored cement floor tiles, colored cement tiles, imitation glazed tiles, concrete floor tiles, colored mortar, colored asphalt, terrazzo, mosaic tiles, artificial marble and wall painting, etc.;

2. Used for various paint coloring and protection materials, including water-based interior and exterior wall paints, powder coatings, etc.; also suitable for oil-based paints including epoxy, alkyd, amino and other primers and topcoats; also used for toy paint , Decorative paint, furniture paint, electrophoretic paint and enamel paint. Iron red primer has an anti-rust function, which can replace high-priced red lead paint and save non-ferrous metals.

3. Used for coloring of plastic products, such as thermosetting plastics and thermoplastics, and coloring of rubber products, such as automobile inner tubes, bicycle inner tubes, etc.
