  • Aqueous size composition with pH regulator
    Patent number: 4656084
    Abstract: Aqueous sizing compositions for glass fibers, comprising both epoxy- and acrylyl- or methacrylyl-functional organosilanes together with fiber-forming polymer and lubricant and pH regulator in a defined amount, are particularly suitable for glass fiber reinforcement for filament winding and pultrusion applications. The use of the pH regulator in the defined amount results in a strand tensile strength of significant improvement.
