    摘要： 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.
