Apr 29, 2016. /Lesprom Network/. Archroma has developed a new concept that gives papermakers the ability to produce truer, cleaner whites with improved print contrast and appearance while reducing consumption of optical brightening agents (OBAs) by up to 20%, as the company said in the press release received by Lesprom Network.

The new concept features a two-component package that combines Archroma’s Cartawhite XL liq – a surface shading solution – with its Leucophor® optical brightening agents. By allowing the separate dosing of these two components, ADVANCED WHITENING provides papermakers with the means to reduce their whiteness costs across all grades.

Archroma had already raised the bar a few years earlier when it developed its innovative Leucophor XL whitening system. This range allowed papermakers to break through their whiteness ceiling to reach previously unattainable levels. The Leucophor XL range improved whiteness build-up without destroying brightness for coated and uncoated papers and board.

“The new concept can save costs across all grades while retaining the advantages of the original whitening approach, not to mention the reduced OBA dosage which means less chemicals in the process and a reduced environmental footprint,” says Andrew Jackson, Global Head Product Management OBA for Archroma.

Archroma is a global leader in color and specialty chemicals.
