SCHWEGO® pur 8025

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


Chemical base:   Polyurethane dispersion
Properties:   SCHWEGO pur 8025 is a non-ionic thickening additive, which improves water-based coating systems as follows:
  • Minimum tendency to splatter during roller application
  • High gloss rentention
  • Perfect flow and levelling properties
During the production and application SCHWEGO pur 8025 improves the following points:
  • Effective colour acceptance when tinting
  • Excellent processing properties
  • Thickening action independent of pH
SCHWEGO pur 8025 improves storage stability and decreases splattering, sagging and through skinning of during application. SCHWEGO pur 8025 may be combined with other thickening additives such as cellulose ethers, bentonites or polyacrylics. SCHWEGO pur 8025 is especially suitable for solvent free systems as it contains only water.
FDA-approval:   The compounds of SCHWEGO pur 8025 are listed in FDA (U.S. Food & Drug Administration), title 21, Code of Federal Regulations (CFR), part 175.105.
Applications:   SCHWEGO pur 8025 is suitable for interior and exterior wall paints as well as for synthetic resin renderings and trowelling compounds or paste fillers based on polyacrylics, styrene copolymers, PU-dispersions or water thinnable alkyd systems. The high gloss retention is shown to particular advantage in glossy emulsion paints when compared with acrylic or cellulose based thickening additives.
