GPL 255
Krytox™ GPL 255 utilizes low levels of fluorescing agents to allow the grease’s appearance to change under an ultraviolet lamp or “black light”. The naturally white grease appears a yellowish-green color once it is exposed to UV light. This allows the grease to be hidden on a white surface under normal circumstances, but easily visible during manufacturing processes. GPL 255 can also allow confirmation that the grease did not migrate. GPL 255 grease is also available in the oil form as the GPL 155.
