Product Overview

Krytox™ GPL255 grease is a special product with fluorescing agent in it to allow the use of a black light to determine the uniformity of an application. It is not intended for routine application as lubricants without qualification testing. The fluorescing additive is present at low levels, but its effect on lubrication performance has not been tested.

Use black like 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.

Under ultraviolet light, the products give 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 almost any industrial supply company.

Krytox™ Greases

Krytox™ greases are nontoxic lubricants that maintain their lubricity and viscosity properties to reduce maintenance costs associated with re-lubrication, component failure, and downtime in demanding applications. They are created by thickening synthetic perfluoropolyether-based oil (PFPE) with polytetrafluoroethylene (PTFE) powder.
