Description:
Castrol Brayco 1728 is a smooth, buttery, translucent NLGI #2 grease. It is based upon a low molecular weight perfluorinated polyether oil and a tetrafluoroethylene gelling agent. Brayco 1728 is nonflammable, chemically, chemically inert to strong acids and alkalies, and is oxidizer compatible. Castrol Fluoroclean X100 and Castrol Fluoroclean HE can be used to remove this lubricant. Refer to the data sheets for Fluoroclean X100 and Fluoroclean HE for information regarding these products.
Application:
Brayco 1728 is recommended for those light duty applications in which lubricant compatibility with aggressive chemicals and oxidants in direct or indirect contact is of primary concern. Brayco 1728 is stable when exposed to both concentrated acids and bases, and oxygen. Perfluorinated greases, in general, exhibit excellent shelf lives due to their intrinsic inertness.

Due to a raw material issue, Castrol is unable to meet their internal specification for manufacturing Braycote 1632. Unfortunately, due to these limitations, the manufacture and sale of Braycote 1632 will be immediately discontinued.

Braycote 1632 is a good all-around grease, excellent for bearing, gears, and actuator lubrication. In addition, relative to some of the other fluorocarbon based alternatives, it is also reasonably like all fluorocarbon based greases, it is excellent for applications requiring good chemical resistance and good vapor pressure characteristics. Braycote 1632 features excellent room temperature outgassing characteristics and good high temperature stability. The recommended temperature range of use for Braycote 1632 is -40?C to +232?C. Before using, be aware of the full range of expected properties and characteristics.
