Skin time (in English skin time) is the time it takes for the formation of a dry film ("skin") on the interface between an adhesive (or sealant) and air. Skin time is then used as a merit figure for adhesive substances.
The skin time depends on the relative humidity and the air temperature at which the substance is exposed, the relative humidity and temperature conditions at which the skin time has been measured must always be specified so that there is a some reproducibility of measurement results.
Typical skin time values range from 10 minutes to a few hours. Notemodify wikitesto
