Publication number: 20220177743Abstract: A method of making a release coated article is described comprising: providing a release coating comprising at least 50 wt. % of monomer(s) comprising an ethylenically unsaturated group and a terminal alkyl group with at least 18 (e.g. contiguous) carbon atoms based on the total amount of ethylenically unsaturated components; crosslinking components(s) comprising at least two ethylenically unsaturated groups; and at least one polymerization initiator. The release coating is substantially solventless, comprising no greater than 1 wt. % of non-polymerizable organic solvent. The method further comprises applying the release coating to a major surface of a substrate; and polymerizing the monomer(s) and crosslinking component(s) of the release coating after applying the release coating to the substrate. Also described are release coating compositions.Type: ApplicationFiled: May 27, 2020Publication date: June 9, 2022Inventors: Junkang Jacob Liu, Christopher A. Merton, Shawn C.

Patent number: 10040953Abstract: Articles having poly(vinyl alcohol) (PVA) and silica nanoparticle multilayer coatings are provided. More specifically, the articles include a substrate and a multilayer coating attached to the substrate. The multilayer coating includes a silica layer that is the outermost layer, the silica layer containing acid-sintered interconnected silica nanoparticles arranged to form a continuous three-dimensional porous network. The multilayer coating also includes a PVA layer disposed between a surface of the substrate and the outermost silica layer. The PVA and silica nanoparticle coatings can be used on a large variety of substrates and tend to be resistant to impacts, scratches, wet abrasions, soil and fog.Type: GrantFiled: April 25, 2014Date of Patent: August 7, 2018Assignee: 3M Innovative Properties CompanyInventors: Justin A.
