Applications & Uses

Applications
  • Lansperse SPA is an APE and VOC free dispersing agent for aqueous pigment dispersions. Lansperse SPA is particularly recommended for the dispersion of Titanium Dioxide. With the use of Kemectant EB3 and Lansperse DS200W pigment loadings of up to 70% can be achieved.
  • Recommended levels based on pigment level: Inorganic Pigments 1 - 4%
  • Incorporation: Incorporate the dispersing agents into the aqueous binder during high-speed dispersion before the addition of the pigments. For higher than 30% pigment loadings this mill base must then be processed through high energy dispersion techniques such as bead mills, basket mills and three roller mills.
