Patent ID: 6918305

Claim:
A method for measuring adhesion of a polymer emulsion binder to a heated surface which comprises: securing a metal plate to a heated platform, said heated platform being at a temperature of at least 350° F. (177° C.); allowing the metal plate to equilibrate to the temperature of the heated platform; applying a polymer emulsion binder to a substrate, wherein the substrate is used in a creping process, to form a coated substrate having a coated side and an uncoated side; attaching an end of the coated substrate to a tensile measuring device; pressing the coated side of the coated substrate onto the heated metal plate; waiting a period of time to allow drying or partial curing of the binder; separating the metal plate from the tensile measuring device at a uniform speed, said substrate attached to said tensile measuring device; and recording the force required to remove the substrate from the metal plate.
