Diresul P Dyes: Enhanced Ecological Profile

Enhanced Ecological Profile |
 |
The liquid sulphur dyes of the Diresul P product range are distinctly different from conventional sulphur dyes. Thanks to innovative research by the Clariant development team in Spain, we have successfully established a product line that is renowned on the market place for combining an ecological profile with economics and industrial safety. Specifically, these products are alkaline solutions of reduced sulphur dyes. The dye molecules are solubilized by adding suitable reducers in an alkaline medium.
All products have very low sulphide content (less than 0.3%). This very low amount of sulphide prevents the danger of undesirable release of hydrogen sulphide during the acidification. |

No additional safety precaution is necessary while using Diresul P dyes. These dyes lend themselves primarily for internal dyeing. They give an intense jet black color, with high coverage and very high light fastness, whilst wastewaters remain clear at all depths. This enables their use in a multitude of applications across the whole range from decor papers up to graphic papers, packaging papers and industrial papers.
