Glass coating composition based on a tin oxide precursor, a silicon oxide precursor and an accelerator

摘要

This invention relates to a composition for coating glass by the deposition of a chemical vapour which comprises a mixture of monobutyl tin trichloride, a tin oxide precursor, a tetraethyl orthosilicate, a silicon dioxide precursor and an accelerator such as triethyl phosphite; the composition is gaseous below 200 degree C and makes it possible to coat glass at a temperature from 450 to 650 degree C at deposition rates in excess of 350 /sec. The layer of deposited material can be combined with other layers to produce an article having specific properties such as controlled emissivity, refractive index, abrasion resistance or appearance.
