    • ‘These sealers are silane or siloxane-based products that react with silica and silicate materials in concrete and with each other to form a hard resin that bonds with the concrete.’
    • ‘But if you open up a tank of silane, you'd better have the fire department on the line already.’
    • ‘The use of thick gels obviated the need for bind silane.’

      • ‘Penetrants such as silanes, siloxanes and blends actually penetrate the brick surface.’
      • ‘Siloxanes are prepolymers - the result of partial polymerization of silanes - in which the molecules are beginning to link, but only in sets of two or three, not yet in full polymeric chains.’
      • ‘Mixtures of silicone resins along with silanes and siloxanes work extremely well at blocking pores of all sizes at low solids levels, without changing the natural appearance of the blocks.’
      • ‘Mixtures of modern synthetic waxes, silanes, and lime-based putty may provide the ideal solution.’
      • ‘That is, the structurally analogous silanes - mixtures of silicon and hydrogen - are spontaneously flammable in air.’


Early 20th century: from silicon + -ane.
