The Levacell/Pontamine anionic powder dyestuffs are particularly suitable for dyeing printing, writing, and sanitary and specialty papers.
Powder dyestuffs are the brands of choice when intensive dyeings are required. In most cases, they are considerably more economical than liquid Levacell/ Pontamine dyestuffs. In addition to requiring less storage space, they have better affinity, better bleedfastness, a lower COD value and cause less staining of the effluent.
To ensure safe and hygienic processing, and in particular to avoid dyestuff dust, the Levacell/Pontamine powder brands are supplied in small packages – repulpable or water-soluble 5 kg bags packed in boxes.
The Pontamine name is used in North America.
