ABSTRACT:
The present invention is directed to a water-based adhesive composition comprising an admixture of a first aliphatic water-based urethane resin that is the reaction product of polycaprolactonediol or polycaprolactonetriol, 4,4-methylene bis(cyclohexylisocyanate), and dimethylolpropionic acid extended with a diamine, and a second aliphatic water-based urethane resin that is the reaction product of 2,6-hexanediol, 4,4-methylene bis(cyclohexylisocyanate), and dimethylolpropionic acid extended with a diamine. The first aliphatic water-based urethane resin comprises from about 99 to about 20 percent by weight of the composition, and the second aliphatic water-based urethane resin comprises from about 1 to about 80 percent by weight of the composition. The invention is also directed to methods of adhering a substrate and a workpiece using the adhesive composition of the invention.
