Abstract
The present invention provides a fiber strand useful in composites and geosynthetics which includes a plurality of fibers having applied to at least a portion of surfaces thereof a base layer of a base coating composition and thereupon a principal layer of an aqueous coating composition different from the base coating composition, the aqueous coating composition including a blend of (1) a halogenated vinyl polymer and (2) an elastomeric polymer, the blend being essentially free of a monoolefinic material.
