0.3%
Oil absorption (g/**0g)****5
Existance of organic tinting matter
Negative
Colour comparison(contrast with standard Speciment)
almost-micro
Comparison of relative tinting strenghth (contrast
with standard specimen) ≥*5
Water soluble chloride and sulfate (indicated by CL-
and SO*-)≤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 *5kg. net
each.
