Publication number: 20230119478Abstract: The present invention relates to coating compositions and methods of forming catalyst-containing coatings on substrates for catalytic heater devices. The coatings are formed by a chemical grafting method, which chemically bonds the coating (and catalysts contained therein) to the substrate. The resulting coatings have high temperature resistance and inhibit or prevent catalyst migration to the substrate, thereby maintaining catalytic activity and desired temperatures over prolonged use.Type: ApplicationFiled: October 12, 2022Publication date: April 20, 2023Inventors: Paul Thottathil, Satyabrata Mukherjee, Purushothaman Kesavan, John Ryan

Patent number: 11492510Abstract: This invention relates to a coating comprising prepolymer and monomers for application onto polyurethane for chemical resistance, abrasion resistance, water proof etc. Usually polyurethane is porous and does not have sufficient stain, abrasion and chemical resistance. The said coatings developed using technology of chemical grafting that involves the use of prepolymers, monomers, catalyst, graft initiator, wetting agents, fillers and other ingredients of the composition. The coating thus obtained when applied on the polyurethane allows obtaining graft polymerization, thereby forming a polymeric film chemically attached to the substrate. The polyurethane substrate is reacted with craft initiator which creates the reaction sites on the substrate via free radical mechanism.Type: GrantFiled: June 16, 2017Date of Patent: November 8, 2022Assignee: ERGOCENTRIC INC.Inventors: Terry Cassaday, John Ryan, Paul Thottathil, Purushothaman Kesavan, Satyabrata Mukherjee

Publication number: 20210041331Abstract: This subject technology relates to a polymeric composition for application onto substrates, such as stainless steel blades, for lubricity, abrasion resistance, and corrosion resistance. The coatings developed using the subject technology of chemical grafting in one aspect involves the use of prepolymer, monomers, catalysts, graft initiator, wetting agent, fillers and other ingredients of the composition. The coating thus obtained when applied on the stainless steel allows obtaining graft polymerization, thereby forming a polymer film chemically attached to the substrate. The substrate is reacted with graft initiators which create reaction sites on the substrate via a free radical mechanism that renders the substrate receptive to attachment of monomers/prepolymers, thus forming a polymeric film that is chemically bonded to the substrate to achieve the desired properties in terms abrasion, wear, lubricity and other properties.Type: ApplicationFiled: July 27, 2020Publication date: February 11, 2021Inventors: Mike Waleryszak, Paul Thottathil, John M. Ryan, Purushothaman Kesavan, Satyabrata Mukherjee

Patent number: 10532956Abstract: This invention relates to polymeric compositions for application onto natural stone in order to provide for long-term chemical, stain, and water resistance, along with antimicrobial properties. Many natural, unsealed stones do not have stain, etch, or water resistance. The described compositions were developed using a technology of chemical grafting that involves the use of prepolymers, monomers, catalysts, graft initiators, wetting agents, antimicrobial agents, and other ingredients. The composition, when thus applied to the stone surface allows it to obtain a graft polymerization, thereby forming a polymer film that is chemically attached to the natural stone, rather than typical physical bonding of other sealer compositions. The natural stones react with a graft initiator in the composition, which creates the reaction sites on the natural stone surface via free radical mechanisms.Type: GrantFiled: August 11, 2017Date of Patent: January 14, 2020Assignee: Questech CorporationInventors: Barry Culkin, Roger Questel, Robert Harrington, Douglas Croteau, Paul Thottathil, Purushoth Kesavan, John Ryan, Satyabrata Mukherjee

Patent number: 9862835Abstract: Provided herein are graft coating formulations for windows that can help reduce or prevent bird strikes via a combination of UV reflectivity and fluorescence. These graft coating formulations may include an acrylic monomer, a diacrylic monomer, a graft initiator, and a catalyst, and when applied to a glass or plastic substrate, may reflect more than about 70% incident light having a wavelength of less than 400 nm, and also may fluoresce when exposed to light having a wavelength of less than about 400 nm. This combination of reflectivity and fluorescence may render the window visible to birds, while still appearing transparent to humans.Type: GrantFiled: August 5, 2013Date of Patent: January 9, 2018Assignee: WINDOWALERT, INC.Inventors: Paul Thottathil, Purushothaman Kesavan, John Ryan, Satyabrata Mukherjee
