Lansperse RPS 11 is a part of our innovative rapeseed biobased product line. Derived from rapeseed, a sustainable crop with no environmental concerns, these products are crafted using our proprietary bioloop technology. In this unique process, two hydrophobes attach to particle surfaces, enhancing the dispersing action and promoting stability.

Functions: Dispersant

Features & Benefits

Applications & Uses

  • Initial work has concentrated on testing these products as highly effective dispersing agents for aqueous systems.
  • Colored iron oxides are only second in volume to TiO2 used in architectural coatings and are traditionally difficult to stabilize.
  • The red iron oxides (Pigment Red 101) have high densities of around 5.0g/cm3 and are prone to settle over a period of time.
  • Lansperse RPS11 appears to wet and stabilize a high pigment concentrate (60%) dispersion with no increase in viscosity in a binder-free aqueous system.
  • Lansperse RPS11 show promise in systems based on Pigment Yellow 74 and carbon black (Pigment Black 7).
