Abstract:
A method for adhering two substrates together comprising the step of applying to at least one substrate, a construction adhesive comprising a polymer made by emulsion polymerizing a mixture of monomers consisting essentially of:(a) 20 to 60%, based on the total weight of monomers, soft acrylic ester monomers (b) 20 to 60%, based on the total weight of monomer, hard monomers c) 1 to 4%, based on tie total weight of monomers, ureido containing polymerizable monomers (d) 1 to 4%, based on the total weight of monomers, vinyl base monomers (e) 1 to 8%, based on the total weight of monomer, polymerize functional acids, and compounds selected from the group consisting of catalyst, chain transfer agents, and optionally, compounds selected from the group consisting of dispersants, defoamers, tackifiers, freeze-thaw inibitors, fillers, thickeners and mixtures thereof, to form a water-based adhesive having a water-based adhesive having a viscosity of between 5,000 and 1,000,000 cps, and subsequent to application of the adhesive, contacting the two substrates for bonding.
