ABSTRACT:
An aqueous coating composition is provided for filamentary materials that yields coated filamentary material with improved weavability and that yields 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 non-selfcrosslinkable elastomeric latex, a carboxylated butadiene polymer, and a phenolic aldehyde condensate polymer. 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. The non-selfcrosslinkable elastomeric latex has a low gel content of less than around 40 weight percent and a low average particle size of less than around 2000 angstroms. The carboxylated butadiene polymer or butadiene styrene copolymer has less than 75 percent bound styrene and about 1 to 10 weight percent carboxylation, where both values are based on the weight of the carboxylated polymer or copolymer. The amount of the carboxylated butadiene polymer or butadiene styrene copolymer in the coating is in the range of 3 to about 10 weight percent on the basis of a dried coating. In addition, the aqueous adhesive coating composition may contain a wax emulsion, and antioxidant.
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.
