Coating Colourants and Performance Claims: A Visible Tint Does Not Identify the Chemistry
The colour of a coating liquid does not reliably identify its formulation, strength or intended surface. Use the product label and current documentation rather than appearance to select or compare materials.
Updated · NANOLAB Knowledge
The key distinction
A visible colour can arise for different reasons, and a photograph is not a compositional analysis. The supplier's appearance specification may be relevant to quality checks, but it should not be confused with a performance ranking. Product identity and release status remain the basis for use.
Practical checks
- Check the exact product and batch information before application.
- Compare any unusual appearance with the supplier's stated requirements.
- Ask technical support about unexplained changes rather than inferring a cause from colour alone.
Example
Illustrative example: two bottles look similar, so an operator assumes they are interchangeable. Their application roles and instructions may differ despite the appearance. A clear identification check prevents a visual shortcut from becoming a product-selection error.
Scope and limits
Do not add colourants to a finished coating or use colour as proof of authenticity. This guide does not establish an acceptable colour range for NANOLAB products. If identity or condition is uncertain, preserve the material for review and obtain a traceable answer before using it on a customer surface.

Amorphous Silica and Quartz: A Material Name Does Not Identify the Finished Coating
Quartz and amorphous silica describe different structural forms of silica. A commercial product called quartz coating should still be evaluated from its own documentation rather than assumed to contain a particular raw-material structure.
