TINTIUM

Tintium pigments developed by Chempon Group are softtextured, producing bright and clean shades with high tinting strength and outstanding single pass dispersibility in Printing Inks, Paints, Plastics and other similar media.

Most of the Yellow and Orange pigments used all over the world are of benzidine (deceptively called diarylide) type or of dangerous metals such as lead, chromium or cadmium. In the case of benzidine (diarylide) pigments, the azo compound cleaves with biological fluids and the carcinogen benzidine is released.

Tintium series of speciality colorants are available presently in 2 colours Reddish yellow, Greenish yellow a.

Tintium pigments are more easily dispersible than any other comparable product.

Tintium is truly the future of the plastics industry. It serves in economical and environmental considerations as well as weatherfast properties

Speciality Chemicals

Harsha Chemicals Pvt Ltd concentrates on the modern so called Green Chemistry to produce ecofriendly chemicals by eco friendly process to replace older generation chemicals and processes. Harsha Chemicals P.Ltd. is a leader in the new generation chelating agents (chelants or sequestering agents)

All the chelating agents manufactured by Harsha Chemicals P. ltd are entirely biodegradable. Biodegradability has been tested to pass OECD (organization for economic corporation and development) under series 301 tests.

EDTA, DTPA and such chelating agents are not biodegradable. So, there is always a danger of remobilization of metal deposited in the earth and passing them back into water bodies. For this reason a number of countries have banned use of EDTA. Even the countries where there is no ban on EDTA and the other old generation sequestering agents are actively looking for better alternatives .EDTA prevents recycling of process water since it continues to remain in the water.
