Alternate #2
Where ambient, and coated metal temperatures, are not at
least 70°F, allow each coat to cure at least overnight in shop
ambient (not warehouse or outdoors).
Alternate #3
Cure in oven, or by other source of even heat (not flame), for
10 minutes, minimum, at a temperature of 310°F ±10.
Alternate #4
Cure in oven, or by other source of even heat (not flame), for
one-half hour, minimum, at a temperature of 200°F ±10°.
Check for Rotation
Finish blower buildup if not completely assembled when coat-
ed. In some instances, it is possible that clearances will be
closed by coating to the extent that some surfaces touch.
This is all right because the coating will wear (abrade) off as
required. However, the blower may be hard to turn initially as
a result. Turn over by hand until the running is free. Do not
try to free up the blower by coupled or belted drive, and do
not try to spin the rotors with shop air. Do not attempt to
use any kind of solvent or cleaner to partially remove, coating
– as this could ruin all of the coating. If necessary, coating
can be scraped for such partial removal.
Complete Removal of Coating
This is for complete removal (to bare metal) of coating and
may require some blower disassembly (depending on blower
size and accessibility) for access to the coated parts and any
overspray. Apply removal fluid liberally with a clean,
“soaked” rag. Vigorously rubbing with this rag and scraping
of the softened coating is required to clean surfaces down to
bare metal, the amount of effort required will vary, depending
upon the solvent used. Some are more effective than others.
Protect surfaces, not coated, from rust.
