0.1 - 2% (Total paint formulations)
Dosage

0.1 - 2.0% on total paint formulation.

We recommend the incorporation after dispersing the pigments and fillers, prior to letting down. In critical systems of under low-shear mixing conditions could a pre-dilution in water or a mixture of water/propylene glycol supplementary induce a homogeneous incorporation. For glossy paints preparation, higher amounts are generally needed. The exact amount required for the respective system should be determined in pre-trials.

Storage & Handling

Storage

Protect from the effects of weather and store at temperatures between 15 and 30°C. Once opened, containers should be resealed immediately after each removal of the product. At temperatures below 15°C, turbidity, gelling, and gel particles may occur. This effect is reversible and does not influence the product efficiency, so warm up to 50°C and mix well before use.
