Catalyst Mixing Calculator

Precise catalyst-to-coating ratios are the difference between a finish that cures right and one that doesn't. Search for your coating below and we'll calculate the exact catalyst weight for your batch.

How It Works

1. Find Your Coating

Search for the exact coating you’re applying by name or SKU.

2. Choose Your Ratio

Select a recommended mixing ratio for your coating, or enter your own.

3. Get Your Weights

Enter your coating weight and we’ll calculate exactly how much catalyst to add.

Why Mixing Ratio Matters

Catalyzed coatings cure through a chemical reaction between the base coating and its catalyst. Too little catalyst and the finish stays soft or tacky; too much and it can go brittle or cure unevenly. Weighing your mix by grams — rather than eyeballing volume — keeps every batch consistent from your first part to your last.

Understanding Your Ratio

Each coating line has a recommended mixing ratio. A lower ratio, such as 6:1, uses more catalyst compared with the amount of coating and will typically produce a higher-gloss finish. A higher ratio, such as 24:1, uses less catalyst and will generally produce a lower-gloss finish. The calculator shows the recommended ratios for your specific coating. If your application requires a ratio outside that range, you can enter a custom ratio directly.

Tips for Accurate Mixing
  • Use a gram scale rather than a volumetric measuring cup — weight-based ratios are far more accurate.
  • Zero out your scale with the empty mixing cup on it before adding your coating.
  • Mix thoroughly and let the batch sit briefly before spraying to allow it to fully activate.
  • Always confirm the recommended ratio on your coating's technical data sheet before your first production run.
Notes
  • DO NOT mix Cerakote and catalyst in plastic containers as this will compromise the integrity of the coating.
  • DO NOT exceed the recommended Cerakote to catalyst mixing ratios.
  • Your Catalyst Weight – This is the weight in grams of catalyst that needs to be added to your selected Cerakote.
  • Your Total Weight – The total weight of Cerakote weighed and catalyst needed is displayed here.
  • Mixing in glass graduated cylinders is recommended. A list of approved plastics is available in the Elite & H-Series and F Series Training Manuals.
  • Use only the recommended strainer size for each coating that is available on each Cerakote bottle and TDS.
