Iron oxide pigment is an inorganic pigment, is part of the iron pigments series, including red iron oxide, yellow iron oxide, brown iron oxide, black iron oxide, etc., whose common point is not soluble in water, with no affinity for cellulose, and It relies on alumina role in fixing the fiber surface and get coloring. Iron oxide pigment light fastness strong, good hiding ability, tinting strength.
Iron oxide pigments in the decorative base paper that is played as a filler, can partially replace the expensive titanium dioxide, but also play the role of pigment dyeing, high prices and can replace polluting organic dye.
Decorative base paper used in the iron oxide pigments technical indicators are as follows: iron oxide (FE2O3) content: not less than 80% (iron oxide black: iron oxide content of not less than 90%): oil absorption: 20-30%; the sieve (325 mesh): not more than 0.5%; water: not more than 1.5%; aqueous composition; not more than 1.0%; PH value of aqueous extract: 5-7.
