PERIGEN ASW 40

PERIGEN ASW 40 is a highly effective dispersing agent for vat, disperse and naphthol dyes. It shows no wetting or washing properties and does not retard vat and disperse dyes. PERIGEN ASW 40 improves the stability of dye baths of vat dyes avoiding precipitations of dyes. It is applied as dispersing agent for dyeings of polyester at high temperature. It keeps its dispersing properties even at temperatures above 120 °C and avoids aggregation of dyestuff remaining in the dye bath during cooling down. Also in jig or pad dyeings agglomerations of dyestuffs are avoided. After steaming PERIGEN ASW 40 relieves removing dyes not having been fixed. At acid pH value PERIGEN ASW 40 shows certain fibre affinity to wool and polyamide.
