Coating Settling: Ask Whether Redispersion Is Permitted

Visible settling needs product-specific interpretation. Some formulations have an approved preparation method; others require investigation.

Updated · NANOLAB Knowledge

Practical approach

Record the product, batch, storage history and appearance, then obtain the manufacturer's instruction before use.

A clear upper layer and sediment below should not be corrected by adding an arbitrary solvent.

Decision limits

Do not assume vigorous mixing restores suitability or that every settled product must be discarded. Follow the responsible technical assessment.
