WATER CONDITIONERS

 

CONCENTRATION

IN WATER

MAGNAFLUX WA2B

A water-soluble granular solid designed to be dissolved in water to prepare a suitable aqueous carrier for the oil suspendable Magnaflux and Magnaglo concentrates. The three-fold actions of Magnaflux WA2B are:

1) to suspend magnetic particles in water;

2) to protect surfaces from corrosion during testing;

3) to wet surfaces under test.

10 g/L

MAGNAFLUX WA4E

A liquid water conditioner which assists suspension of Magnaflux or Magnaglo particles very efficiently, wets surfaces and protects them from corrosion during tests. Magnaflux WA4E also leaves light corrosion protection after testing.
