Claim 1
Independent Claim
83 words
METHOD OF APPLYING GLASS-RESIN COUPLING COMPOSITION TO GLASS COMPRISING THE STEPS OF COOLING A GLASS FILAMENT IN ITS NASCENT STATE IN AN ANHYDROUS ESSENTIALLY CHEMICALLY INERT ATOMOSPHERE TO REDUCE THE GLASS BELOW A PREDETERNINED TEMPERATURE, AND IMMEDIATELLY THEREAFTER CONTACTING THE FILAMENT WITH THE VAPOR OF AN ALKYL ALKOXY SILANE GLASS-RESIN COUPLING AGENT COMBINED WITH AIR CONTAINING MOISTURE, TO HYDROLYZE THE COUPLING AGNET, SAID PREDETERMINED TEMPERATURE BEING THE THERMAL DECOMPOSITION TEMPERATURE OF THE COUPLING AGENT, AND MAINTAINING SAID COUPLING AGENT AT ITS VAPORIZATION TEMPERATURE.
