Usage:
Iron Oxide Pigment has good physical and chemical properties. soda-resisting:
It is very stability to alkaline matter, such as cement and lime. It has no weathering function to cement and has no function to its strength. acid-resisting: It has relative stability to ordinary weak acid and thin acid, but does not resist to powerful acid. light-resisting, weather-resisting: It has best light-resisting and weather-resisting. Its color can not be changed by shine upon strongly .heat-resisting: Its color can not be changed under relative temperature, the limit temperature for various products is as follows:
fine-resisting, dissolve-resisting:It can not be dissolved to water, all various mineral oil and vegetable oil and organic solvent.It can be broadly used for pigmentation in building man-made marble, and colorful cement. It’s pigment for watercolor, paint color, paint, and rubber, plastic color, also can used for magnetic material industry.
