Rheological additive for water-based coating systems, free of VOC, APEO and organotin

Chemical base: Polyurethane dispersion
Properties: SCHWEGO pur 8350 is a non-ionic thickening additive, which has a beneficial influence on the rheological properties of aqueous paint and varnish systems in these respects:
  • Thickening effect independent of pH
  • Minimum tendency to splatter when using roller
  • Effective acceptance of colour when tinting
  • High gloss retention
  • Good flow and levelling properties
  • Very good brush stability
SCHWEGO pur 8350 can be combined with other thickening additives in order to achieve special effects.
Applications: SCHWEGO pur 8350 is suitable for interior and exterior wall paints, water-based coatings and anticorrosive coatings, modified resin plasters and fillers based on fine size Polyacrylates, Styrene copolymers, Vinylacetate- or PUR-dispersions. SCHWEGO pur 8350 shows a high gloss retention in glossy emulsion paints compared to acrylic and cellulosic thickening additives.
