Advantage of " EMPEROR" iron oxide black on Paint industry :

As iron oxide black excellent on acid and alkali resistant used on coating industry, also low cost, it will widely used on exterior paint and primer. After years of development, Our company promote range of black iron oxide 311,313, 920, 810 series.

Direction for used on coating industry:

• 1: The iron oxide suitable for the coloring and protection of all kinds of paints and coatings. Such as alkyd resins, amino alkyd, vinyl chloride resin, polyurethane, nitro, polyester paint. In addition, also applies to the electrophoretic paint. Primer, enamel, pencil paint, mixed paint, baking, anti-rust paint, floor paint waterline paint. It can be used for water based coatings, powder coatings and plastic coatings. And paint used in toys, decorative paint, furniture paint, house paint, paint the garage, parking lot paint, automobile paint, and so on.
• 2: Usage method: Generally divided into three steps: wetting, grinding and dispersion (paint). Iron oxide pigments and paints, fillers for ingredient mixing tank, dubbed coarse paste, depending on the amount of solvent added to the viscosity of the resulting employ different milling equipment, such as mastics available triple roll mill fine, thin pulp available efficient sand mill (vertical or horizontal) or a ball mill. Primer is generally about 50 microns, about 40 microns finish requirements, and then in the paint tank, add resin, drier, solvent to dispersion(paint), coloring, adjust the viscosity, and finally Filtered, and product packaging.
