Welcome to M. R. Silicone Industries.

Simethicone (Activated or Defoamer Oil)

MRSI-SD 100 is a 100% Silicone Defoamer. It is widely used as a versatile Defoamer, in both general industrial applications. In medical and pharmaceutical applications, the requirements for this chemically inert silicone Defoamer is unique and exacting.

Typical Applications.

    Industrial operations:
  1. Adhesives: Paper coating processes.
  2. Agar: Paper production processes.
  3. Asphalt: Petroleum Pitch.
  4. Cutting Oils: Propane Gas.
  5. Detergents & Soaps: Rubber Lattices.
  6. Fermentation Processes: Resins & Varnishes.
  7. Filtration Processes: Salt Solutions.
  8. Gas Scrubbing: Steel-Pickling solutions.
  9. Hot Aqueous systems: Textile Processes.
  10. Insecticides: Vacuum distillations.
  11. Oil Quench Baths: Wool Fats.
  12. Polishes: Wire-Drawing compounds.

How to use:

  1. Amount:
    Amount is effective in very low concentrations. 1 to 50 gms per ton of foamer are sufficient to suppress most foams.
    For any new industrial application, the user may start with a concentration of 20 gms per ton, then increase or decrease this concentration until most economical use level, is established.
  2. Direct application as supplied:
    In some applications, it may be wiped on process equipment to limit foaming level. In bottle filling machine, it is applied to the nozzles to knock down foam as it rises in the neck of the bottle, Similarly, a wiped on a application on the rim of processing vats prevents foam overflows. It may be wiped on a screen which is then suspended over the surface of the foamer. Whenever the foam rises too high, it contacts the screen and is broken.
  3. Solvant dispersion:
    In most industrial applications, it is diluted with solvent, then added to foamier; dispersions may be made in Butyl Alcohol, Toluene, Xylem, Kerosene, Ethyl Ether, Chloroform and many other Solvents. Comparative tests using different diluents should be run if it is desirable to determine the most suitable and economical diluent to use for any particular process or product. Freshly prepared dispersion should be used for maximum efficiency.
