Bluesil™ Silanol Fluids

Solution for adhesives, coatings, sealants

These polydimethylsiloxane fluids are linear polymers with reactive, terminal silanol groups. They are clear, water-white, tasteless and odorless. The approximate viscosity of the fluid is designated in the product name. They are used in a wide range of applications where silanol reactivity provides condensation cure.

Silanols are useful in adhesives, coatings, sealants, etc., where reactivity and cost-effectiveness are critical.


  • Lower viscosity fluids can be used as plasticizers in silicone elastomers, as base polymers for silicone water repellents and as hydrophobizing agents in treating silica or other fillers.
  • Low and medium viscosity fluids are effective in textile and paper coatings.
  • Medium viscosity fluids impart water repelling properties and softness to natural textiles such as cotton
    fabrics and paper. More permanent water repellency can be obtained by curing-in-place a coating of a
    medium viscosity silanol fluid with a functional silane.
  • The higher viscosity fluids are recommended for formulating silicone condensation systems used in sealants, adhesives, coatings and other room-temperature vulcanizing systems.


Silanol Fluids are useful intermediates in the manufacture of

  • Paper coatings
  • One and two part silicone room temperature vulcanizing (RTV) sealants and mold making compounds
  • Silicone foams
  • Organofunctional siloxane polymers

Silanol Fluids can also be reacted with organic formulation ingredients.
