Abstract
A method is provided for producing a more stable emulsion of a polyester resin having carboxyl functionality and an amino-functional silane coupling agent that is incorporated into a sizing composition for treating glass fibers. The method involves reacting the polyester resin having carboxyl functionality with the amino-functional silane at ambient temperatures and atmospheric pressure then diluting the reaction product of the polyester resin and silane to obtain a more stable emulsion. The emulsion is then incorporated into a sizing composition by the addition of typical sizing additives to produce a more stable sizing composition.
