OVERBAKING TEST – powder cured with different temperatures

We performed the test: “Study related to the different curing temperatures of the powder, with evaluation of the overbaking” in our Decoral® Laboratory.

We prepared the samples with the same powder in our Laboratory. Keeping the same curing time, increasing the temperature, the shade of the final powder became different. This was analysed by a laboratory spectrophotometer.

This modification, related to the modified chromophore power of the pigments, is called OVERBAKING.

This modification could be also caused by an excess of the curing time in the oven.

The compliance with the curing conditions (time and temperature), which are indicated on the technical data sheets, are the main parameters to be used to get a good result.
