Marinus Bio-40 Hydraulic Fluid is a blend of natural esters which provide excellent rust and oxidation resistance to metal components. The additive package is designed to provide unequalled, anti-wear and load carrying properties, minimize foaming, enhance demulsibility, and maintain a high degreee of biodegradability. Marinus Bio-40 Hydraulic Fluid also has the following intrinsic characteristics:

Ideal choice for lubricating pneumatic systems where the lubricant is exhausted into the air. Much less oil is required to provide a strong lubrication film for components resulting in a healthier workplace environment.
Meets and exceeds the requirements of biological degradation as defined by the OECD guidelines and the CEC L-33-A-93 test method.
Extend the frequency of hose replacement, with the net effect being increased production output.
Readily separates water using an advanced additive package that greatly reduces, if not eliminates, the problems associated with water.

- Marinus Bio-40 Formula Update -

Maryn International Ltd. has been developing environmentally friendly and biodegradable lubricants for over 20 years and Marinus Bio-40 has been an attractive product to many clients who are searching for biodegradable hydraulic oil. In August of 2007, work began to revise this formula and improve its performance properties in a cost efficient manner, to produce a top tier hydraulic oil at a competitive price. After extensive testing, the new formula has been completed and represents the latest additive technology to produce a premier biodegradable hydraulic oil with enhanced demulsibility and improved anti-foaming properties. The updated formula (rev 2.0) is completely compatible with our original Marinus Bio-40 (rev 1.0). The following chart summarizes the specific physical characteristics of Marinus Bio-40. Specific detailed information follows.

Density ASTM D 1298: This test method covers the laboratory determination using a glass hydrometer, of the density, of petroleum products normally handled as liquids, and having a Reid vapor pressure of 101.325 kPa (14.696 psi) or less. Values are measured on a hydrometer at ambient temperature and corrected to 15°C using the Petroleum Measurement Tables.

Kinematic Viscosity ASTM D 445: This test method specifies a procedure for the determination of the kinematic viscosity, υ, of liquid petroleum products, both transparent and opaque, by measuring the time for a volume of liquid to flow under gravity through a calibrated glass capillary viscometer. The dynamic viscosity, η, can be obtained by multiplying the kinematic viscosity, υ, by the density, ρ, of the liquid. The result obtained from this test method is dependent upon the behaviour of the sample and is intended for application to liquids for which primarily the shear stress and shear rates are proportional (Newtonian flow behaviour).

Viscosity Index ASTM D 2270: This practice specifies the procedures for calculating the viscosity index of petroleum products, such as lubricating oils, and related materials from their kinematic viscosities at 40 and 100°C. Values were calculated using an extrapolation method outlined in 1.1.2. Procedure B - For petroleum products of which the viscosity index is 100 or greater.

Pour Point ASTM D 97: This test method is intended for use on any petroleum product. After preliminary heating, the sample is cooled at a specified rate and examined at intervals of 3°C for flow characteristics. The lowest temperature at which movement of the specimen is observed is recorded as the pour point.

Flash Point ASTM D 92: This test method describes the determination of the flash point and fire point of petroleum products by a manual Cleveland open cup apparatus. This flash point and fire point test method is a dynamic method and depends on definite rates of temperature increases to control the precision of the test method. It's primary use is for viscous materials having flash point of 79°C (175°F) and above. It is also used to determine fire point, which is a temperature above the flash point, at which the test specimen will support combustion for a minimum of 5 s. Approximately 70ml of test specimen is increased rapidly at first and then at a slower constant rate as the flash point is approached. At specified intervals a test flame is passed across the cup.

Water Separability (Demulsibility) ASTM D 1401: This test method covers measurement of the ability of petroleum oils to separate from water. This method provides a guide for determining the water separation characteristics of oils subject to water contamination and turbulence. It is used for specification of new oils and monitoring of in-service oils. The procedure involves a test specimen consisting of a 40ml sample and a 40ml quantity of distilled water that are stirrred for 5 minutes at 54°C in a graduated cylinder. The time required for the separation of the emulsion thus formed is recorded either after every 5 minutes or at the specification time limit. If complete separation or emulsion reduction to 3ml or less does not occur after standing for 30 minutes or some other specification time limit, the volumes of oil (or fluid), water, and emulsion remaining at the time are reported.

Foaming Characteristics ASTM D 892: This test method covers the determination of the foaming characteristics of lubricating oils at 24°C and 93.5°C. The sample, maintained at a temperature of 24°C (75°F) is blown with air at a constant rate for 5 minutes, then allowed to settle for 10 minutes (Sequence I). The volume of foam is measured at the end of both periods. The test is repeated on a second sample at 93.5° (Sequence II), and then, after collapsing the foam, again at 24°C (Sequence III).

Oxidative Stability ASTM D 2272: This test method utilizes an oxygen-pressured vessel to evaluate the oxidation stability of oils having the same composition in the presence of water and a copper catalyst coil at 150°C. The test oil, water, and copper catalyst coil are contained in a covered glass container and placed in a vessel equipped with a pressure guage. The vessel is charged with oxygen to a guage pressure of 620kPa (90 psi, 6.2 bar), placed in a constant-temperature oil bath set at 150°C, and rotated axially at 100rpm at an angle of 30° from the horizontal. The number of minutes required to reach a specific drop in guage pressure is the oxidation stability of the test sample.

Rust Protection ASTM D 665B: This test method covers the evaluation of the ability of inhibited mineral oils to aid in preventing the rusting of ferrous parts should water become mixed with the oil. A mixture of 300ml of the oil under test is stirred with 30ml of salt water (NaCl) at a temperature of 60°C with a cylindrical steel test rod completely immersed therein. The test is run for 4 hours. The test rod is observed for signs of rusting and, if desired, degree of rusting.

Copper Corrosion ASTM D 130: This test method covers the determination of the corrosiveness to copper of hydrocarbons having a vapor pressure no greater than 124kPa (18 psi) at 37.8°C. The copper strip corrosion test is designed to assess the relative degree of corrosivity of a petroleum product. A polished copper strip is immersed in a specific volume of the sample being tested and heated at 130°C for 3 hours. At the end of the heating period, the copper strip is removed, washed and the colour and tarnish level assessed against the ASTM Copper Strip Corrosion Standard.

Water in Crude Oils by Potentiometric Karl Fischer Titration ASTM D 4377: This test method covers the determination of water in the range from 0.02 to 2% in crude oils. After homogenizing the crude oil with a mixer, an aliquot of the crude, in a mixed solvent, is titrated to an electrometric end-point using Karl Fischer reagent.

Evaluating the Scuffing Load Capacity of Oils (FZG Visual Method) ASTM D 5182: This test method, the Forschungstelle für Záhnräder und Getriebebau (Research Site for Gears and Transmissions) Visual Method, commonly referred to as the FZG Visual Method, is intended to measure the scuffing load capacity of oils used to lubricate hardened steel gears. Scoring, a form of abrasive wear, is also included as a failure criteria in this test method. It is primarily used to assess the resistance to scuffing of mild additive treated oils such as industrial gear oils, transmission fluids, and hydraulic fluids. An FZG Gear Test Machine is operated at constant speed (1450 rpm) for a fixed period (21700 revolutions - approximately 15 minutes) at successively increasing loads until the failure criteria is reached; the initial oil temperature is 90°C beginning at load stage four. The test gears are examined initially and after the prescribed duration at each load stage for cumulative damage (scuffing) to the gear tooth flanks.
