Method for forming coatings from radiation curable compositions containing alkenyl ether functional polyisobutylenes

摘要

A method for forming coatings from radiation curable compositions comprising an alkenyl ether functional polyisobutylene, a cationic photoinitiator, and optionally a free radical photoinitiator and/or an alkenyl ether compound which is free of isobutylene units on to components such as fiber optics where the component is at a temperature greater than about 50° C. and preferably at a temperature within a range of greater than about 80° C. to 120° C. The coating may be overcoated with an acrylate functional polymer.
