Sodium Methylsiliconate

№ UN:  1760
H.S. Code:  3824 99 700 0
Main applications: 
  • In construction to impart hydrophobic properties to various materials and products;
  • For the protection of building materials against moisture and harmful atmospheric influences, which allows:
  • Increase the durability of the erected structures and reduce the costs of their repair;
  • To give the material frost resistance, crack resistance and lightfastness;
  • Increase the general thermal insulation properties of the structure;
  • To give the material excellent water-repellent properties, long-lasting in time;
  • Does not change the appearance of the protected material, its gas permeability and air permeability;
  • In oil production as a modifier of clay muds, which allows:
  • Provide increased lubricity;
  • Reduce the flow of water into the drilling mud from the rock;
  • Reduce and stabilize the viscosity of the drilling fluid.
