Coating Concentration Percentages: State Mass, Volume or Mass per Volume

A percentage needs a defined basis. Mass percent, volume percent and mass-per-volume expressions are different quantities, so a coating or cleaner specification should state which one is intended.

Updated · NANOLAB Knowledge

The key distinction

A bare percentage can create ambiguity during purchasing, testing or approved preparation. The denominator and units determine what the value means. Conversions may require density or other information, and they should not be made by assuming that every liquid has the properties of water.

Practical checks

  1. Preserve the complete concentration notation from the supplier.
  2. Ask for clarification when the basis is missing.
  3. Use a checked conversion only when the required supporting information is available.

Example

Arithmetic example: ten grams in a final mixture of one hundred grams describes ten percent by mass. Ten millilitres in a final volume of one hundred millilitres describes ten percent by volume. Those statements do not establish the same composition for every material.

Scope and limits

This article does not provide a mixing recipe for NANOLAB products. Follow the exact supplied instructions and do not dilute a coating unless the manufacturer authorizes it. The purpose is accurate interpretation of a documented quantity, not improvisation of a formulation or a stronger working solution.

Related guidance

Ask NANOLAB about the exact product and intended use. Use the current product documentation for formulation-specific instructions.
