Abstract

A sizing composition including water, a polyvinylpyrrolidone film former, a silane coupling agent, a lubricant, and a surfactant is provided. The polyvinylpyrrolidone film former constitutes from 30 wt. % to 50 wt. % of the dry solids of the sizing composition. Wet use chopped strand glass fibers for use in reinforcing gypsum board are also provided. The wet use chopped strand glass fibers include chopped glass fibers having the sizing composition applied thereto. The sizing composition improves fiber bundle integrity, fiber flow rate, fiber flow rate consistency, and dispersibility of the wet use chopped strand glass fibers in a gypsum matrix or slurry.
