Coating method for modifying adhesion of thin films to substrates
摘要:
A method is taught for that allows for controlling and optimizing the level of adhesion between a multilayer composite applied to a support web. The method comprises the steps of selecting the support web with or without a subbing layer applied thereto; selecting an organic solvent that is substantially free of other constituents as a carrier layer; forming a multilayer composite including the carrier layer, the carrier layer being the lowermost layer thereof; applying the multilayer composite to the support web or the subbing layer; drying the multilayer composite on the support web, the carrier layer evaporating from the multilayer composite; testing the adhesive strength between the support web or subbing layer and the multilayer composite after drying; and repeating these steps until a desired level of adhesion is found.
