ROYCO HF-825 is a concentrated solution of a methacrylate-polymer in synthetic diester based oil which provides both lubricity and a 'tacky' film.
ROYCO HF-825 is ashless so it will not cause deposits or coke formation in the oil, wetted sections of engines or hydraulic systems. The product is used as an assembly aid for bonding components in multi-component mechanisms such as gearboxes, pumps, and engine accessories. Additionally it is also used to coat or lubricate O-rings prior to pressing them into cavities thus preventing chafing or tearing of the O-ring surface. As ROYCO HF-825 is commonly used as a viscosity index improver in many lubricating oils, there is no cause for compatibility concerns when used in contact with the oil-wetted areas of the lube system.
