Dispersogen SPG

Stabilizer for biocide-free paints

Edition Date :
May 06, 2019
Dispersogen SPG is a low viscous, nonionic stabilizer for mineral paints containing potassium water glass, such as silicate and organosilicate paints. In combination with the cationic stabilizer Dispersogen SPS, Dispersogen SPG reduces the increase in viscosity during storage and helps to improve the rheological profile of the paint.

The recommended dosage is 0.2 – 0.8% in the paint formulation. Dispersogen® SPG has a renewable content of 75 %, is VOC/SVOC-free and does not require any hazard labeling.  It is therefore a suitable ingredient for ecolabel certified paints.

Performance benefits:

Stabilizers are crucial additives for mineral paint systems as they improve the paints rheology and application profile while enhancing the storage stability. In combination with Dispersogen SPS, the product helps to:

  • lower the yield point of the paint formulation and thereby contribute to a more fluid paint appearance.
  • achieve good leveling and surface performance
  • improve the paint's thixotropic profile. Thus, less efforts are required to homogenize the paint formulation
  • extend paints shelf life due to low impact on viscosity and pH during storage


Sustainability benefits:

  • VOC/SVOC-free (below the detection limit according to ISO 11890-2 and 16000-9)
  • Based on renewable resources (renewable share 75%)
  • Free of human and environmental hazard label
  • German water hazardous class WGK 1
  • Readily biodegradable
In combination with Dispersogen SPS, the Dispersogen SPG is used as stabilizer for silicate paints and organosilicate paints.
