Abstract:
A method and system for forming a multi-layer film, comprising corona treating a surface of a substrate in a processing environment having a positive pressure and an oxygen concentration of about 100 parts-per-million by volume or less, and coating the corona-treated surface of the substrate with a coating material while the substrate is within the processing environment.
Abstract:
Polymeric fibers and methods of making the polymeric fibers are described. The polymeric fibers are crosslinked hydrogels or dried hydrogels that are prepared from a precursor composition that contains polymerizable material having an average number of ethylenically unsaturated groups per monomer molecule greater than 1.0. The polymeric fibers can contain an optional active agent.
Abstract:
Methods of making a (e.g. dilute) cleaning solution from a hydrogel cleaning concentrate, packages of hydrogel cleaning concentrate, and methods of making a hydrogel cleaning concentrate are described.
