Polyether-modified Styrene Maleic Anhydride|PMS | Polyether Modified SMA

Introduction and application of Polyether-modified Styrene Maleic Anhydride|PMS | Polyether modified SMA

This water-based polymer material contains dye-affinity groups and is free of APEO and low
in VOCs. It exhibits excellent wetting, dispersing, and compatibility properties, making it
particularly suitable for the milling of disperse dyes; it prevents dye precipitation, flocculation,
and agglomeration, while enhancing printing and dyeing performance as well as the storage
stability of the dye paste.
Application: Preparation of eco-friendly liquid disperse dye slurries in the textile printing and
dyeing industry.
Usage: Add during the grinding of disperse dyes (water-based; free of resins, amines, and
co-solvents). First, thoroughly mix and disperse the additive in water, then slowly add the
disperse dye filter cake (calculated on a dry-weight basis).
