Backed by many years of experience, research and development Denso have produced an extremely versatile range of cold applied petrolatum based mastics.

Used in conjunction with other Denso products, they provide economical efficient solutions to the problems of long term corrosion protection as well as water and gas proofing.

With the benefit of easy handling and conformability they are primarily used as filler materials to afford smooth profiles to awkward shapes such as mechanical joints, flanges and valves.

They are also used for general sealing, filling and caulking applications.
