Properties
S - Suitable, L - Limited Use, N - Not recommended
PropertiesSpecific surface areas range from 15 sq.m/g in highly
opaque types to 75 sq.m/g in transparent types.PO 34 prints are
fast to paraffin, di-octoyl-phthalate and tolerate clear lacquer
coatings.It may crystallize in many printing inks.Transparent PO 34
is somewhat sensitive to heat upto 100-140 C. Higher sterilization
or metal decorative printing may cause a colour shift towards
redder orange. They generally exhibit insufficient solvent fastness
for decorative printing inks, especially monostyrene and
acetone.
PropertiesIt also performs poorly as far as light fastness is
concerned and bleeds into solutions of melamine resins, which
precludes its use in such fields.Textile industry however uses it
to an appreciable extent.Its dry cleaning solvent resistance is
excellent and withstands exposure to dry heat upto 200C. It
performs similarly with spin dyeing of polyacrylonitrile.It is used
to colour plasticized PVC due to excellent light fastness (4 on
blue wool scale)at levels above 0.1% else blooming takes place.At
higher conc. The pigment tends to bleed but is considerably more
stable to light than weaker PO 13.It is rarely used in polyolefins
as it only withstands exposure to 200C, and its opaque colourations
show insufficient light fastness.It tends to bloom especially in
extrusion products made of low M.Wt LDPE.
PropertiesThey are recommended for variety of compound types
from aromatic PU foams to cast resins of polyesters in which
pigment slightly delays hardening process.In baking enamels the
pigment is not fast to overpainting.Opaque rather than transparent
ones are used in paint industry.Excellent flow props. Make it
possible to further increase pigment level and opacity for
exceptionally good results for an organic pigment. Ex. At same
pigment conc. it is more opaque than Molybdate Red of same colour
hue range.Full shades of very opaque type are light, weather and
high tolerance for solvents and migration.In printing inks thermal
stability increases from120C for transparent to 200C for opaque
ones.Combinations with other coloured pigments like iron oxide,
nickel titanium yellow and collaborations reduced with TiO2 are
much less fast.
