Characteristics

CONTRA-SOL works through targeted, controlled flocculation of the pigments. This will above all Floating and settling of the pigments is prevented. CONTRA-SOL is for medium to low-polarity, solvent-based and solvent-free paint systems and increases thixotropy. Used in anti-corrosion primers, the anti-corrosion properties can be improved in many applications.

Processing

The addition should be made at the start of production. The following guide recipe can be used to break down bentonites: 80 parts by weight solvent 10 parts by weight bentonites 10 parts by weight additive The solvent should only be aromatics or white spirit containing aromatics. Should the If gelation is not sufficient, the addition of polar solvents can be useful.

Use during the production process

CONTRA-SOL is optimally added to the dispersing / grinding batch, i.e. when the binders and liquids for the dispersing / grinding batch have been submitted, CONTRA-SOL is added while stirring. Then the powdered components are added and dispersed / ground. Then the approach is completed with the remaining components of the recipe. After completion, the approach should rest (mature) for 24 hours so that the full effectiveness of the CONTRA-SOL can unfold.

Storage recommendation

Stir well before use. Keep container in a cool, well-ventilated place. Occasionally, traces of water may be contained, which have no influence on the effectiveness of the product and the quality. In order to maintain the product quality, the original container should be closed again immediately after each removal. The described properties of CONTRA-SOL are retained for at least 2 years if stored properly.
