Product Description

Acid Releaser VSA is an acid releaser for dyeing polyamide fabrics with acid dyes or metal-complex dyes. As the dyeing temperature rises it releases acid and thereby lowers the pH, allowing the dyestuff to exhaust gradually, fully and in an orderly manner.

Performance & Benefits

  • Acid Releaser VSA is a pH-sliding auxiliary for acid dyeing: the pH shifts in response to changes in temperature.
