Krytox™ GPL 155 | GPL Oil with Fluorescent Indicator
Long-Lasting Lubrication that is Easily Visible under UV Light
Krytox™ GPL 155 is a specialty oil with fluorescing agent additives to allow the oil to be easily visible under an ultraviolet (UV) light or “black light” to determine the uniformity of an application. Under ultraviolet light, the product gives off a yellowish-green color that is visible to the unaided eye. Krytox oils are long-lasting solutions that exhibit high penetration. Exposing GPL 155 to a broad spectrum UV light can confirm the oil reached the desired area of lubrication. Also, when the oil is applied in an ultra-thin layer it can be nearly impossible to see with the naked eye; however, with the addition of UV light to the surface of the lubricated area, even trace amounts of GPL 155 become easily visible. Increasing the visibility of the grease allows the user to be confident they lubricated the entirety of the surface, and also know when it is time to re-lubricate. Due to their inert nature and stability, Krytox fluorinated lubricants provide a much longer usable life as compared to typical hydrocarbon oils and greases, and the longer usable life allows them to remain for considerable periods of time before needing to be replaced, if they are replaced at all. That translates to savings over time, both by lowering the amount of lubricant purchased and any downtime incurred during re-lubrication.
The fluorescing agent is suspended in the Krytox™ GPL 155 because of the addition of our Krytox™ 157 FS surfactant to the oil. The Krytox™ 157 FS is acidic, and its effect on various materials is unknown. The grease matrix of the Krytox™ GPL 255 holds the fluorescing agent in place without the use of surfactant. This oil is not intended for routine applications as a lubricant without qualification testing. The fluorescing additive is present at low levels, but its effect on lubrication performance has not been tested.
