Application notes
ISOFLEX TOPAS NCA 5051 is easy to apply to the lubrication point by means of a brush or a common metering device. In gears it is applied with a dip-feed system. If the product is stored for a longer period of time, oil may collect at the surface due to the soft consistency. A homogenous texture is regained by mechanical stirring.
