INSURAL 3000 Mastic Sealing Compound
INSURAL™ 3000 mastic sealing compound provides an airtight seal between the cathode bar and the end of the cathode, significantly reducing oxidation of the cathode.
INSURAL 3000 also acts as a compressible seal to close gaps in an anode baking oven between the oven’s long and short walls.
