  • Composition for encapsulating signal transmission devices
    Patent number: 6101308
    Abstract: A signal transmission device comprising an encapsulated segment produced by a method which comprises contacting the segment of the signal transmission device with an effective amount of a room-temperature curable composition comprising:(1) a hydroxy-functional compound having a molecular weight of greater than 500 and a hydroxy functionality of 2 or more;(2) an epoxy-functional compound having an epoxy functionality of 2 or more; and(3) a curative catalyst, in an amount effective to crosslink the epoxy and hydroxy components of the respective epoxy-functional and hydroxy-functional compounds.
    Type: Grant
    Filed: March 10, 1999
    Date of Patent: August 8, 2000
    Assignee: Uniroyal Chemical Company, Inc.
