Dynagard E™ Environmental Wire Rope Lubricant

Dynagard “E” Hoover Dam, Colorado River, Nevada, USA

Dynagard “E” is a revolutionary non-toxic, biodegradable Wire Rope Lubricant that meets the performance levels of petroleum-based greases in areas of fluid film and corrosion protection of Wire Rope Strands. Exceptional for manual application: Dynagard “E” also meets the operational requirements for all Kirkpatrick Wire Rope Lubrication System Models providing for optimum coating and penetration prolonging the working life of Wire Rope while at the same time meeting the environmental concerns of our Customers. Dynagard “E” was the first seed oil based high viscosity grease introduced onto the world market in 1993. It also was the benchmark product used in 2002 to establish MIL-PRF18458C Type II requirements under the Environmentally Preferable Lubricants program (NSWCCD, Code 632) for the United States Navy’s Naval Sea System Command. Documentation is available upon request.

Dynagard “E” and its components have been evaluated by independent laboratories. Using 3rd party test results, The Kirkpatrick Group, Inc. has determined that it is fully compliant for the VGP definition of an Environmentally Acceptable Lubricant (EAL).

Chemex International UK Comments After testing:  The report states the biodegradable Lithium grease is not readily soluble in cold or hot water. It was vigorously shaken/homogenized which would not occur in any lubrication mechanism in which the product would be exposed offshore. Also, the relative insolubility of the grease to water at any temperature would result in exposure limits infinitely lower than the values generated from this series of tests. Current field experience in fresh and salt water environments shows no toxic effects are observed despite prolonged exposure to a wide variety of environments. (Chemex)
