It is a soft, brown petrolatum-based compound that displaces moisture and penetrates existing rust.
It is primarily used as a primer before applying Denso petrolatum tapes to aid adhesion and provide long-term anti-corrosion protection for pipes, flanges, and valves.
The paste does not dry, harden, or crack, and it can be applied to wet surfaces.
It is also used as a rust preventative for screw threads, valve spindles, and wire ropes.
