Mix well before use.
Ideally, it is best diluted to 10% or less before use, although
it may be used as received. In continuous overflow systems, like
pH sumps, 10 ppm is usually sufficient, but unusually heavy
foam-producing chemical loads, like certain types of fusing
oils, may require as much as 100 ppm.
Defoamer will be metered using a holding tank and a metering
pump into a pH adjustment sump. For emergency use, a hand
trigger sprayer is effective in eliminating large foam masses.
