ABSTRACT:
A coating composition for producing coated glass fiber strands and the coated glass fiber strands are provided, where the coated strands have good knot tensile strength and improved processability. The coating composition has a carboxylated elastomeric latex, an elastomeric plasticizer, a hydrophilic/lipophilic agent, an antioxidant, wax emulsion, anti-foaming agent, tertiary amine, polyhydroxylated glycol, and a pH in the range of about 8.7 to about 9.5. The coated glass fiber strand has the aforementioned coating in an amount of about 10 to about 20 (LOI) loss on ignition.
