Iron Oxide Red 130s

Iron oxide red have excellent exquisite, superb weatherability, fine dispersion, strong tuning power, stable performance, and is a green and environmentally no-toxic paint, has excellent lightfastness, good heat resistant and alkali resistant.
Good dispersion/hiding power is strong/strong tinting strength.
Widely used in building materials industry, plastic products, coating color, fine grinding materials.


1. Characteristics:
Iron oxide red is an inorganic substance with the chemical formula Fe2O3, which is a red or dark red amorphous powder. The relative density is 5~5.25, and the melting point is 1565°C (decomposition at the same time). Insoluble in water, soluble in hydrochloric acid and sulfuric acid, slightly soluble in nitric acid. The hiding power and tinting power are very strong, and there is no oil permeability and water permeability. Stable in the atmosphere and sunlight, resistant to foul gas, high temperature and alkali.
