Abstract
The present disclosure is directed to a two-component bonding agent composition and a process for applying a layer of the bonding agent composition to substrate layers to make laminates.
Description
technical field [0001] The present disclosure relates to two-part acrylic-urethane adhesives employing waterborne acrylic / urethane hybrid compositions. The present disclosure is particularly suitable for use as a laminating adhesive and for use in, for example, laminating flexible films, aluminum foils, and other substrates. Background technique [0002] Solvent-based polyurethanes have been widely used as laminating adhesives for good heat and moisture resistance. In recent years, it has been desired to expand the selection of commercially available adhesives (including, for example, adhesives and primers) to meet an increasing number of new technology applications. The desire to reduce chemical solvent emissions and improve ease of handling has driven the need for improved waterborne binder systems. One such system that has gained popularity in a wide range of applications is the latex system; that is, an aqueous dispersion or emulsion. Especially attractive are acrylic...
