PCWI Four-sided Anodised Aluminium Wet Film Thickness Combs
PCWI
Four-sided Anodised Aluminium Wet Film Thickness Combs. These wet film
combs are used to measure the thickness of a wet coating prior to it
curing, drying or solvents flashing off. These wet film combs will
determine the wet film thickness (WFT), from this, the dry film
thickness can be calculated, Note 1 this is on a smoothe surface such as
a prepainted surface. Note 2 An area of measurement that is little known
or forgotten is that, if the wet coating is on an abrasive blasted
surface, the coating that fills the profile and the coating above the
profile will dry and shrink together, so as a whole, the total dry
coating thickness will be thinner than anticipated. Should you be using
Australian Standard AS 3894 dry film thickness measurement, would be
kinder than measuring the DFT over the profile as some do, but shouldnt.
