ABSTRACT:
There is disclosed herein, as a new article of manufacutre, a glass substrate coated with tin oxide and a method of making the same. According to the method, in order to produce the new article of manufacture, a glass substrate with a selected surface is heated to a temperature sufficiently hot so that a heat decomposable, tin-containing material coming into the vicinity of the selected surface will be heat decomposed permitting the tin contained in the tin-containing material to be oxidized and deposited as tin oxide on the selected surface. The tin-containing material, which is applied to the heated glass surface is a coating material containing alkyltin alkoxides of the general formula RSn(OR.sup.1).sub.3 where R and R.sup.1 are organo groups containing from 1-6 carbon atoms, whereby a thicker coating film of oxidized tin is deposited on the selected surface of the glass substrate than can be deposited by previously used tin coating materials under the same application and temperature conditions. The new product of manufacture has particular utility when used as a "Low E" glass product for building glazings which reflect infrared radiation back into a building in which such glazings are installed thereby to keep the building warmer.
