This part of ISO 8130 specifies a method for the
determination of the time for a thermosetting
coating powder to gel at a specified temperature,
normally 180 °C.
NOTE1 The determination of the gel time is a very simple
method for the characterization and quality control of coating
powders. However, the gel time determined by this method is not
directly related to the time for a coating powder to cure in
practical applications.
The method is not applicable to coating powders
with ultra-short gel times (less than 15 s).
