UWG-7 Underwater Grease
UWG7 is a grease developed to function in water, based on the technology of GRP Thixo Grease, which has excellent lubrication performance.
This grease is a special grease that demonstrates excellent lubrication performance over long periods of time in parts that are constantly operated in water, and lubricated parts that are constantly splashed with a large amount of water.
It has the ability to maintain excellent lubrication performance for a long time even in 10% acid water.
This condition represents a fairly poor lubrication environment. Compared to many other greases, it is much more resistant not only to water but also to solutions and oils.
Features
This grease is a chemically synthesized grease that synthesizes components with high resistance to acid water and chemically activated water, based on specially produced glycol.
The strength of the lubricating film of this grease is several times higher than that of regular greases, and it has excellent lubrication performance.
This grease has strong absorptivity for metal surfaces under the conditions of contact with water, acid water, or various liquid chemical substances.
Therefore, unlike other greases, it does not easily flow off or disappear from the metal surface in water.
Furthermore, this grease also has a high rust prevention effect.
