Patent number: 11335551Abstract: The present method comprises providing a flexible web substrate (e.g., polymeric flexible web substrates) that forms at least part of a component of a device, coating so as to wet-out on and cover all or a substantial portion of a major surface on one side or both sides of the flexible web substrate with flowable polymeric material, while the flexible web substrate is moving in a down-web direction, and solidifying the polymeric material so as to form one cleaning layer on the major surface of one side or both sides of the flexible web substrate. The present invention can be utilized in a continuous in-line manufacturing process. In applications of the present invention where the flexible web substrate will not form a component of a device, the present invention broadly provides a method for cleaning particles from a flexible web of indefinite length.Type: GrantFiled: October 24, 2019Date of Patent: May 17, 2022Assignee: 3M INNOVATIVE PROPERTIES COMPANYInventors: William R.

Patent number: 9841534Abstract: Optically clear adhesive or coating layers can be prepared by preparing a curable mixture, coating the curable mixture to form a layer, partially curing the curable mixture, drying the coated layer, and fully curing the curable mixture. The curable mixture may also be partially cured and then coated, dried and fully cured. The curable mixture includes two free radically polymerizable monomer compositions that are relatively incompatible and a transient compatibilizer, such as a solvent. Polymers of the two monomer compositions, if polymerized separately and blended, form phase separated domains. The curable mixture provides for adhesive or coating layers that are optically clear.Type: GrantFiled: December 13, 2011Date of Patent: December 12, 2017Assignee: 3M Innovative Properties CompanyInventors: Scott M.

Patent number: 9333533Abstract: It has now been determined that a first coating layer may be applied to a substrate by a first coating die in a much thinner layer than its rheological properties and/or surface properties would normally allow. This is accomplished by using a second coating fluid dispensed from a second coating die acting as a “dynamic liquid squeegee” to transport, spread, even, or meter the first coating layer on the substrate by varying a gap between the second coating die and the substrate.Type: GrantFiled: November 21, 2011Date of Patent: May 10, 2016Assignee: 3M Innovative Properties CompanyInventors: William R.
