Soluble Oil B
Soluble Oil B is a premium metal-working lubricant designed for a variety of applications where heat dissipation is critical. It is a compounded emulsifying product composed of a high-quality base oil and select emulsifiers, with the addition of a potent bactericide ("B"). It mixes readily with hot or cold water and forms a stable creamy emulsion, and is usually diluted in oil/water ratios ranging from 1:1 to 1:6 depending on the application.

Soluble Oil B is an emulsion designed for grinding and for machining operations where cooling characteristics are critical. Although mixture ratios vary for specific applications, in general, the richer emulsions are used for the more difficult cutting operations, where the intermediate mixtures are used for the free-machining operations, and the lean mixtures are used for operations such as grinding, where massive cooling is required. AVAILABILITY: Soluble Oil B is available at Varouh Oil, Inc. Warehouses in 5 gallon pails, 55 Gallon drums or in bulk quantaties.

Soluble Oil B forms homogeneous and exceptionally stable emulsions, which show no apparent separation after long periods of usage or storage. An effective bactericide helps prevent the buildup of bacteria under normal operating conditions. Additionally, it offers the following benefits:
Excellent lubricity Quality surface finish Extended tool life and long wheel life in grinding operations Outstanding heat dissipating characteristics in severe operating conditions Good rust and corrosion protection of both ferrous and non-ferrous metals, leaving a thin film of protection on machined parts
