Properties

S - Suitable, L - Limited Use, N - Not recommended

Properties Specific 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.

Properties It 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 200ºC. 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 200ºC, and its opaque colourations show insufficient light fastness.

It tends to bloom especially in extrusion products made of low M.Wt LDPE.

Properties They 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 from120ºC for transparent to 200ºC for opaque ones.

Combinations with other coloured pigments like iron oxide, nickel titanium yellow and collaborations reduced with TiO2 are much less fast.
