Patent number: 11795326Abstract: Compositions include a compound preparable by reaction of components comprising an optionally crosslinked polyethylenimine and at least one an amine-reactive hydrolyzable organosilane represented by the formula R—Z—SiY3. R represents an amine-reactive group containing 1 to 18 carbon atoms; Z represents a divalent organic group containing 1 to 8 carbon atoms; and each Y independently represents a hydrolyzable group. Methods of using the compositions to make articles, and articles produces thereby are also disclosed. A composition comprising an intimate mixture of a crosslinked polyethylenimine and a polymeric binder material, and a method of making it is also disclosed.Type: GrantFiled: October 23, 2020Date of Patent: October 24, 2023Assignee: 3M Innovative Properties CompanyInventors: Naiyong Jing, Kevin D.

Patent number: 10792383Abstract: A method of disinfecting a medical device comprises three steps. First, a disinfectant is contacted with a process indicator and the medical device. The disinfectant comprises at least one aldehyde. The process indicator contains a synthetic amine-containing compound disposed on a substrate. The synthetic amine-containing compound comprises at least one of primary amino groups or secondary amino groups, and is reactive with the disinfectant to form at least one adduct. The synthetic amine-containing compound and the medical device are in fluid communication through the disinfectant. A predetermined disinfectant exposure criterion exists for contacting the disinfectant with the medical device. Second, the process indicator is spectrally observed and at least one parameter is obtained therefrom that is predictive of the predetermined disinfectant exposure criterion. The third step is determining that the predetermined disinfectant exposure criterion has been achieved.Type: GrantFiled: April 25, 2017Date of Patent: October 6, 2020Assignee: 3M Innovative Properties CompanyInventors: Naiyong Jing, Ryan T.

Publication number: 20100077932Abstract: Methods and systems for flexographic printing are discussed. The methods include removing solvent from a material to be transferred from a donor substrate to a feature of a flexographic printing plate. Solvent is removed from the material prior to transfer to the feature, resulting in improved transfer of the material to the feature. The systems include solvent removal apparatuses for facilitating removal of solvent from the material.Type: ApplicationFiled: November 5, 2007Publication date: April 1, 2010Applicant: 3M INNOVATIVE PROPERTIES COMPANYInventors: Mikhail L. Pekurovsky, Ryan T. Woldt

Publication number: 20100024671Abstract: Methods of forming a flexographic printing plate are described and include disposing a polymeric substrate onto a master tool having a plurality of recesses defining a master tool pattern. A solvent is disposed within the recesses. Then, the solvent is diffused into the polymeric substrate to form a substrate relief pattern that is complementary to the master pattern. The substrate relief pattern is then cured to form a flexographic printing plate. Flexographic printing plates are also described.Type: ApplicationFiled: November 5, 2007Publication date: February 4, 2010Inventors: Mikhail L. Pekurovsky, Ryan T. Woldt
