Coating Fluids

UCON™ LB Series base fluids can be compounded with selected rust and oxidation inhibitors to serve as lubricating and protective coatings for hydraulic brake parts and similar equipment before and during assembly. They are compatible with DOT 3 brake fluids but not silicone-based fluids. UCON coating fluids have no adverse effect on braking system elastomers and provide lubrication during the assembly of braking parts.
