methyl hydrogen polysiloxane

20 - 25 cst Viscosity And Odorless Methyl Hydrogen Silicone Oil For Gypsum Board

methyl hydrogen polysiloxane that is end-capped with trimethyl siloxy groups. The product is primarily
used to treat powders to keep them dry, as an anticaking material and is highly water-repellent.


  • Clear, colorless fluid

  • Formulated to waterproof gypsum board, plasterboard and plaster block

Methyl Hydrogen Silicone Fluid are used as:
 Water repellent treatment of plaster used to produce tiles and boards,
 Water repellent treatment of cement, marble, fabrics, glass, ceramics, leather and metal,
 Water repellent treatment of dry-sprayed substances (e.g.: extinguisher powders, various
 Raw material of MH emulsion; Blend with hydroxyl silicone emulsion could keep the
fabric with both breathable and waterproof property. It also could improve the fabric
tear strength, friction strength and antifouling, feeling and stitching performance,
 Used as a release paper isolation and crosslinking agent.

If you produce water proofing gypsum board,methyl hydrogen silicone fluid is a good choice as water resistant agent.The viscosity can be adjusted,with technic to take off the low boiling substances.
