Special NLGI Grade 2 PFPE Grease with Added Fluorescing Agents for Easy Detection Under Black Light. Base Oil Viscosity 160 cSt @ 40°C
Krytox™ GPL 255 Grease is a special lubricant that appears white with added fluorescing agent in the oil to allow for easy detection under UV or black light to determine the uniformity of application.
Krytox™ GPL 255 is not intended for routine application as a lubricant without proper qualification testing. The fluorescing additive is present at low levels, but its effect on lubrication performance has not been tested.
Base Oil Viscosity, cSt
20 °C (68 °F) = 550
40 °C (104 °F) = 160
100 °C (212 °F) = 18
NLGI Grade 2 (penetration 265-295)
Appearance - White and buttery
Primary Chemistry: PFPE (Perfluoropolyether)
Allows the use of a black light to determine the uniformity of an application.
Difficult to Identify Leaks & Grease Placement
Frequent Grease Migration & Lubricant Loss
Incredibly Short Lubricant Usability Life
Krytox™ GPL 255 is for use under black light to uncover surface areas where grease coverage is absent. For applications requiring 100% surface coverage or for applications with surface areas intentionally excluded from being covered by grease such as use on seals, valves, O-rings, and bearings.
Under ultraviolet light, Krytox™ GPL 255 gives off a yellowish green color that is visible to the unaided eye. The only equipment necessary is a standard broad spectrum ultraviolet lamp, commonly known as a “black light”, lamps that emit long wave ultraviolet light in the 365 nm range are available from most common industrial supply company.
