Abstract
Abstract An aqueous coating composition for filamentary materials that are to be used in reinforcing elastomeric matrix materials is provided that renders reinforced elastomeric materials having improved properties of flexibility and fatigue resistance. The aqueous adhesive coating composition has a vinyl-pyridine-containing copolymer or terpolymer latex, a phenolic aldehyde condensate polymer, and a non-self-crosslinkable elastomeric latex with a low gel content of less than around 40 weight percent and a low average particle size of less than around 2000 angstroms. The vinyl pyridine-containing elastomeric latex is produced from a vinyl pyridine-containing monomer, 1,3 diene hydrocarbon monomer or the terpolymer is produced in the same way with the addition of a vinyl containing monomer. In addition the aqueous adhesive coating composition may contain a wax emulsion, antioxidant, and carboxylated styrene butadiene copolymer latex. The aqueous adhesive coating composition is used to treat filamentary material which are then dried or dried and partially cured, and combined with the elastomeric matrix material to produce reinforced elastomeric products.
