Patent number: 11932775Abstract: A curable coating composition is provided having multi-functionalized acrylic copolymer and silicone imine resin curing agents. The acrylic copolymer of the curable coating composition has, in polymerized form, epoxy functionalized groups and cure compatibility groups and the silicone imine forms an amino-functional silicone in the presence of water. The coating compositions are useful in the field of superior weatherable and durable coatings and are useful to replace isocyanate-containing polyurethane based coatings. Also provided are coated articles produced from the curable composition.Type: GrantFiled: July 17, 2019Date of Patent: March 19, 2024Assignees: Dow Global Technologies LLC, Dow Siliicones CorporationInventors: Alan M. Piwowar, Ray E. Drumright, Erin B. Vogel, Gary M. Wieber, Patrick J. Fryfogle, Yanxiang Li, Susan M. Machelski, Paul J. Popa, Adam C. Tomasik, Gerald Lawrence Witucki

Patent number: 9598576Abstract: The present invention relates to a curable silicone composition comprising: (A) an organopolysiloxane having at least two alkenyl groups and at least one aryl group in a molecule, (B) an organopolysiloxane having at least two silicon atom-bonded hydrogen atoms in a molecule, (C) an organopolysiloxane having at least one aryl group in a molecule and containing a metal atom selected from the group consisting of V, Ta, Nb and Ce, and (D) a hydrosilylation-reaction catalyst. The present invention can provide the curable silicone composition, which does not develop a crack by thermal aging and further can form a cured material that exhibits less yellowing.Type: GrantFiled: September 3, 2014Date of Patent: March 21, 2017Assignees: DOW CORNING TORAY CO., LTD., DOW CORNING CORPORATIONInventors: Tadashi Okawa, Tomohiro Iimura, Sawako Inagaki, Mayumi Mizukami, Michitaka Suto, Haruhiko Furukawa, Randall G.

Patent number: 9556327Abstract: An additive for a silicone encapsulant has the structure: Formula (I) wherein R1 and R2 are each —O—Si(R4)(R5)(R6) and each of R4, R5, and R6 is independently chosen from C1-C10 hydrocarbyl groups, C1-C10 alkyl groups, C2-C10 alkenyl groups, and C6-C10 aryl groups, and wherein R3 is independently chosen from C1-C10 hydrocarbyl groups, C1-C10 alkyl groups, C2-C10 alkenyl groups, and C6-C10 aryl groups. The additive is formed using a method that includes the step of reacting iron metal or an iron (III) compound with a hydroxyl functional organosiloxane. An encapsulant includes the additive and a polyorganosiloxane. The encapsulant can be utilized to form a device that includes an electronic component and the encapsulant disposed on the electronic component. The device is formed using a method that includes the step of disposing the encapsulant on the electronic device.Type: GrantFiled: September 2, 2014Date of Patent: January 31, 2017Assignee: Dow Corning CorporationInventors: Don L Kleyer, Randall G Schmidt, Adam C Tomasik, Shengqing Xu

Patent number: 9493634Abstract: An additive for a silicone encapsulant has the structure: (I) R1Ce(OSi—R2) I I a R3 wherein a is 3 or 4, wherein R1 and R2 are each —O—Si(R4)(R5)(R6) and each of R4, R5, and R6 is independently chosen from C1-C10 hydrocarbyl groups, C1-C10 alkyl groups, C2-C10 alkenyl groups, and C6-C10 aryl groups, and wherein R3 is independently chosen from C1-C10 hydrocarbyl groups, C1-C10 alkyl groups, C2-C10 alkenyl groups, and C6-C10 aryl groups. More specifically, the cerium is cerium (III) or (IV). The additive is formed using a method that includes the step of reacting cerium metal or a cerium (III) or (IV) compound with a hydroxyl functional organosiloxane. An encapsulant includes the additive and a polyorganosiloxane. The encapsulant can be utilized to form a device that includes an optoelectronic component and the encapsulant disposed on the optoelectronic component. The device is formed using a method that includes the step of disposing the encapsulant on the optoelectronic device.Type: GrantFiled: September 2, 2014Date of Patent: November 15, 2016Assignee: DOW CORNING CORPORATIONInventors: Don L Kleyer, Fumito Nishida, Randall G Schmidt, Adam C Tomasik
