1[mass noun] A colourless gaseous compound of silicon and hydrogen which has strong reducing properties and is spontaneously flammable in air.
- ‘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.’
- ‘They can contain chemicals such as acrylate, peroxides, bisphenol, formaldehyde, hexane, hydroquinone, phenol, polyurethane, silane, toluene, and xylene, some of which have been suspected of toxicity.’
- 1.1[count noun]Any of the large class of hydrides of silicon analogous to the alkanes.
- ‘That is, the structurally analogous silanes - mixtures of silicon and hydrogen - are spontaneously flammable in air.’
- ‘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 modern synthetic waxes, silanes, and lime-based putty may provide the ideal solution.’
- ‘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.’
- ‘Penetrants such as silanes, siloxanes and blends actually penetrate the brick surface.’
Early 20th century: from silicon + -ane.
