MP-3000 Sealant

MP-3000 Sealant at IGS Industries

MP-3000 is a refractory mastic gasket material that has several uses in the continuous molten metal casting industry, including dummy bar packing, sealing molds to floors, anti-splash guard on SENs, and many more. As the joint is coupled, MP-3000 will flow to seal off rough or irregular surfaces, and then will expand up to 20% as heat is applied.

MP-3000 is superior to Vee board for several reasons:

  • No need for exact measurements on cutting packing for dummy bars. MP-3000 is supplied in spools or cut-to-length segments and will smash together at the overlap joint to give you 100% solid coverage. Mold packing time is cut in half with MP-3000 and is much simpler to accomplish.
  • Will not contaminate zones or water filtration systems. MP-3000 disintegrates to dust after the dummy bar moves out of the mold. There are no long fibrous strands that will hang in the zones or clog filters.

MP-3000 is available in a non-RCF formulation for environmental purposes, as well as an extended-shelf-life blend.
