Why Is My Coating Discoloring After the Cure Cycle?

COLOUR STABILITY

Some colours within Cerakote H-series have a “Colour Stability (F°) Max Temperature” that is lower than the “Coating Stability (F°) Max Temperature”.

Colour Stability means that at a certain temperature the pigments within the coating will be subject to color shift through the thermal curing process.

This effect can be more prevalent with lighter pigmented colours such as white, yellow, or orange.

Before you cure your next lighter pigmented H series colour, look up the “Colour Stability (F°) Max Temperature” in the H-series Tech Data Sheets (TDS), found on the Cerakote website, to determine the max curing temperatures.

Cerakote recommends curing all metal parts coated in H-Series with our standard curing cycle of 250°F for 2 hours to ensure proper performance in durability and aesthetics (discoloration of any coating will not occur at 250°F for 2 hours).
