    Red

    Specification

    Iron content(indicated by Fe2O at 105ºC baking ≥ 95%

    Volatile matter at 105ºC≤1.0%

    Matter soluble in water≤0.3%

    Water extraction liquid acidity & allkality ≤20 ml

    PH value of water suspension 5-7

    Residue on sieve(63μm)≤0.3%

    Total calcium content(indicated by CaO)  0.3%

    Oil absorption (g/100g)15-25

    Existance of organic tinting matter Negative

    Colour comparison(contrast with standard Speciment) almost-micro

    Comparison of relative tinting strenghth (contrast with standard specimen) 95

    Water soluble chloride and sulfate (indicated by CL- and SO4-) ≤0.2%

    Lead chromate Negative

    Notes: 1) The standard specimen for relative tinting strength of the colour should be decided through the negotiation between the plant and customer two sides.

    2) In case of the sample colour shade, the test sample is fresher than which of the standard, the grade of colour difference is “slight”, now the product should be of the first class.

    Usage: pigment used in paint,rubber,plastic,buiding,cement,ceramic,etc.

    Packing: In plastic lined plastic woven bag of  25kg. net each.
