Blend of a carboxylated copolymer latex and of an acrylate copolymer latex for coating rubber and product

A composition of a blend of a carboxylated copolymer latex having a Tg of not less than about -30 DEG C. such as a copolymer of styrene, itaconic and methacrylic acids and butadiene-1,3 and an acrylate copolymer latex having a Tg of not less than about +30 DEG C. such as a copolymer of ethylacrylate...

Beschreibung
Zusammenfassung:	A composition of a blend of a carboxylated copolymer latex having a Tg of not less than about -30 DEG C. such as a copolymer of styrene, itaconic and methacrylic acids and butadiene-1,3 and an acrylate copolymer latex having a Tg of not less than about +30 DEG C. such as a copolymer of ethylacrylate, methyl methacrylate and acrylamide containing a minor amount by weight of a heat sensitizer sufficient to gel the composition and which also can contain fillers, wetting agents and stabilizers, and so forth can be used to provide a water resistant film on the surface of a hot rubber compound or composition which subsequently can be cooled rapidly with water and dried. The resulting latex coated rubber can then be stacked or assembled without sticking.
