At what percentage of relative humidity and temperature, is amine blush likely to occur?


Selected Answers

From Zenith Czora of Parex Davco on November 24, 2020:
Amine blush is caused by high humidity, low curing temperatures and the presence of moisture and excess carbon dioxide in the atmosphere. it will likely to occur if a relative humidity of 85% at 21 deg. centigrade or 75% at 10 oC is exceeded and if the substrate temperature is 5 oC below the dewpoint.

From Janssen Christophe of Lassarat on November 24, 2020:
For sure the Humidity is important, but first of all you must take care of the dew point and make sure that the applied coating will not be submited to condensation before full cure time
