CASTROL Braycote 631A

Explanation

Castrol Braycote 631A is a smooth, buttery, translucent white NLGI #2 lubricant based on perfluoroether oil.

This oil is fireproof and chemically inert in general. It is thermally stable both singly and singly.

the presence of oxygen has extremely low volatility and no tendency to form sediment. Castrol Fluoroclean ™

X100 and Castrol Fluoroclean ™ HE can be used to remove this lubricant. See the data sheets for more information

regarding these products.

most organic solvents and materials except fluorinated solvents. Compatible with all commonly used devices

metals, plastics and elastomers. This product may be adversely affected by Lewis acids such as aluminum

chloride, at high temperatures. Scrub surfaces of aluminum, magnesium or titanium under certain conditions

conditions can cause thermal degradation of the lubricant. Such systems should be thoroughly evaluated.

Surfaces must be well cleaned from organic rust inhibitors before applying grease to ensure proper lubrication.
