Abstract
The binder composition of this invention contains a beta-hydroxy urethane functional material and a polycarboxylic acid. Coated glass fibers are prepared by contacting said fibers with the binder composition of the invention and thereafter curing the composition. This invention is also an improved method of treating glass fibers by contacting them with the improved binder composition of the invention.
