Features & Benefits
- Superiority Of Gloss White-1516 Over barium Sulphate and Alumina Hydrate
- Barium Sulfate: 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.

Uses In Printing Inks
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).
Uses In Rubbers & Paints
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
Transparency & Printing Qualities
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 color strength for multicolour printing.
Uses in Paper
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.
Other Applications
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 Colors and Crayon Colors etc.
