ABSTRACT:
A sprayable adhesive based on nonionic neoprene latex includes in the adhesive mixture a nonionic surfactant, along with the latex, which is a copolymer of chloroprene and methacrylic acid stabilized with polyvinyl alcohol. The adhesive also includes a tackifier, zinc oxide, and an antioxidant. The tackifier is a petroleum-derived hydrocarbon resin, and the antioxidant is a hindered bis-phenol. In order to obtain a rapid drying adhesive, only the latex and surfactant are mixed as liquids. The remaining ingredients are added in solid form and dispersed by mixing under high shear. The adhesive can be applied by spraying from a canister using dimethyl ether as a propellant.
