Usage and Dilution Instructions

For most conditions use 1/2 to 1 ounce per gallon of water. Water flow rate for most situations should be 2 gallons per hour per cubic foot mass of machine. For example, a 20 cubic foot vibratory machine should require a flow rate of 40 gallons per hour. This product provides excellent overnight or over the weekend corrosion protection for steel media. If machine is not used for prolonged periods of time, additional corrosion protection may be required using a corrosion inhibitor such as our PR-100, 50-R or MP-222. LB-770 does not contain any harsh ingredients.
