Abstract
Solid tin (IV) compounds, free from carbon-tin bonds, and containing both chlorine and fluorine are used to apply infra red reflecting fluorine containing tin oxide coatings to glass. Examples of the tin compounds that may be used are ammonium hexahalostannates of the formula (NH.sub.4).sub.2 SnHal.sub.6 wherein Hal represents halogen, and a minor atomic proportion of the halogen present is fluorine and the balance is chlorine. The tin compounds are dispersed in finely divided form in a carrier gas, and the suspension of the tin compound in the carrier gas is directed on to a hot glass surface to be coated.
