Optical Brightener Quenching Agent:
GLOQUENCH PAS - GLOQUENCH DS

Optical Brightening agents (OBA) are very widely used in a large range of paper products. There are however some products within the industry which do not allow any fluorescence or OBA content at all. The production of these sorts of grades can be complicated by the use of mill broke, waste paper, or other fiber sources which may carry some amounts of OBA. In these cases it is necessary to extinguish or "quench" the fluorescence which may be present in trace or moderate amounts.

GLOQUENCH PAS is one of the most powerful OBA quenching agents available. This product has proven to be 25% to 40% more effective than most other quenching agents available in the market today. Small additions of GloQuench to the pulper or machine chest can provide very high levels of quenching to OBA containing papers. In most cases the fluorescence of residual OBAs can be completely extinguished.

GloQuench is available in two strengths. GloQuench PAS (full strength) and GloQuench DS which is somewhat reduced in concentration.
