GLOSS WHITE is a companion product to light ALUMINA HYDRATE . The use of GLOSS WHITE as a dry pigment powder has also been confined mainly to PAPER & INK applications. Gloss white is valued for its soft, non abrasive texture and its excellent working and printing properties. It is less susceptible to "Livering" than light ALUMINA HYDRATE .

Although GLOSS WHITE is more expensive than a mechanical blend of 3BaSo4/Al(OH)3, the coprecipitate is favored on the basis of superior processing characteristics and reduced tendency to absorb drier from ink vechicles on storage

GLOSS WHITE has a specific oil absorption and this property enables it to impart a significant viscosity increase to lithographic printing inks (improves the working properties of the ink).

It has found some use as a rubber filler to increase tear resistance. Earlier GLOSS WHITE has not been used in paints due to its high cost, high oil absorption and chemical reactivity

In multicolour printing where inks trap over each other, it is obviously an advantage to have transparent inks after the first one. ALUMINA HYDRATE qualifies very well as a transparent extender when an ink needs to be reduced in colour strength for multicolour printing.

GLOSS WHITE improves BRIGHTNESS, OPACITY, SMOOTHNESS, POROSITY, INK RECEPTIVITY, GLOSS, WHITNESS, K and N value, SOA value (Surface Oil absorption value), QUICK DRYING.

GLOSS WHITE also improves the pH value thus increasing Gloss, quick drying of Ink and reduce Ink consumption resulting good printability.

The costly chemicals like TITANIUM DIOXIDE, ZINC OXIDE, CALCIUM CARBONATE and ALUMINA HYDRATE can be replaced by "GLOSS WHITE" to get the same results of opacity and brightness. There is no problem in dispersing GLOSS WHITE and also the binder requirement is the same as other pigments. The coated products will be better where coating slip includes GLOSS WHITE.

In a number of inks, a blend of clay and ALUMINA HYDRATE can be used as the extender to arrive at a low cost and acceptable printing qualities. However, if the printing run be a long one, it is safer to select a good printing extender to prevent piling on the rollers and on the printing plates.

Most of the paper manufactures have reduced there consumption of Titanium Dioxide to nearly 50% by using GLOSS WHITE-1516.

They have replaced 100 parts of Titanium Dioxide by addition of 50 parts of Titanium Dioxide and 50 parts of GLOSS WHITE - 1516 and thus reducing cost without any change in quality..

Barium Sulphate	:	It would improve Brightness, Opacity and minimize Porosity and blackening on Calendar & Super Calendar.
ALUMINA HYDRATE	:	Improves Whiteness and Ink Receptivity and Gloss
GLOSS WHITE	:	Improves BRIGHTNESS, WHITENESS, OPACITY, SMOOTHNESS, GLOSS, INK RECEPTIVITY and MINIMIZE THE BLACKENING.
DOSAGE
For Paper Industry	:	Those who are using Titanium Dioxide can use 50% TiO2 & 50% GLOSS WHITE-1516 to reduce the cost without affecting the quality.
Paper Coating Industry	:	Can replace TiO2, ZnO and other Pigments to get equivalent results. This improves SOA and K and N value required for fast multicolor printing & ink gloss

GLOSS WHITE finds application as an extender and filler pigment in PRINTING INKS, PAPERS like COATED PAPER, DUPLEX BOARDS, COATED DUPLEX BOARDS, MAP LITHO PAPER, XEROX PAPER, TISSUE PAPER, WRITING PAPERS, NEWS PRINT, (and other varities of paper) RUBBER, ADHESIVES, POSTER COLOURS and CRAYON COLOURS etc.
