ACIDON-PA | Acid donor and pH sliding agent

Product Information

Acidon-PA is specially developed acid donor, based on sliding pH principle. Acidic pH is obtained with increase in temperature unlike conventional buffer which maintains pH irrespective of temperature. Acidon-PA is used for dyeing of polyamide, wool and their blends with acid dyes. Acidon-PA can be dosable.
