Dispersogen SPV

Stabilizer for biocide-free paints

Edition Date :
September 27, 2019

Dispersogen SPV 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 SPV reduces the increase in viscosity during storage and helps to improve the rheological profile of the paint.

The recommended dosage is 0.3 – 1.0% in the paint formulation. Dispersogen SPV is low VOC, APEO-free and suitable for ecolabel certified paints.

Benefits

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:

  • Low VOC
  • Free of alkylphenol ethoxylates
  • Suitable for ecolabels such as European Ecoflower, German Blue Angel, Scandinavian Nordic Swan or French NF Environment

 

Composition:   amine derivative
Active content: approx. 20%
Appearance: yellowish liquid
pH value, 10% aqueous solution: approx. 11
Solubility: soluble in water, not soluble in mineral spirit and aromatic solvents
Density: approx. 1.02 g/cm3
Flash point: > 100 °C 
Dosage: about 0.3 – 1.0 weight % in the paint
Mode of dosage:  Dispersogen SPV is added to the formulation at the initial stage together with wetting and dispersing agents and the inorganic pigments to the mill base. After stirring potassium silicate and optionally the polymer emulsions are added.

Dispersogen SPV is an amine derative that stabilizes the viscosity of silicate and organosilicate paints.
