Powder Cure Window with measured cure value of 30 min or °F: a worked example

This scenario runs the powder cure window calculation on the strong side: measured cure value of 30 min or °F, with every other input held at its documented default. Use this calculator for practical powder coating or surface finishing planning, quoting, troubleshooting, or line setup.

The inputs for this scenario

  • Measured cure value (peak metal temp or dwell): 30 min or °F (raised for this scenario; the documented default is 12)
  • Minimum cure spec limit: 10 min or °F (unchanged)
  • Maximum cure spec limit: 18 min or °F (unchanged)

Working through the calculation

  • Applying the documented formula (Inside window when actual value is between minimum and maximum) to the inputs above produces each figure below.
  • At this operating point the engine returns 0 outside for inside window, the number this scenario is built around.
  • At this operating point the engine returns -12 value for nearest margin.
  • At this operating point the engine returns 10 value for lower limit.
  • At this operating point the engine returns 18 value for upper limit.

How this compares with the baseline

  • Against the tool's baseline example, where measured cure value sits at 12 min or °F and the headline result is 1 inside, this scenario comes in 100% below the baseline at 0 outside.
  • Use it when reviewing oven datalogger profiles, dwell-time readings, or peak-metal-temperature (PMT) records against the powder's technical data sheet. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Inside window: 0 outside (headline result)
  • Nearest margin: -12 value
  • Lower limit: 10 value
  • Upper limit: 18 value
