Title:
SYNTHESIS AND DEVELOPMENT OF POLYURETHANE COATINGS CONTAINING FLOURINE GROUPS FOR ABHESIVE APPLICATIONS
Document Type and Number:
WIPO Patent Application WO/2017/116612
Kind Code:
A3
Abstract:
Various embodiments provide epoxy modified fluorinated urethane compositions that may provide desirable bulk mechanical properties of conventional coatings, adhesives, or structural matrix resins, while simultaneously exhibiting surface properties that may reduce surface contamination. Various embodiments provide formulations comprising epoxy modified fluorinated alkyl ether including urethane oligomer or polymer resins that may possess the requisite thermal, mechanical, chemical, and optical properties while achieving low surface energy. In various embodiments, such resins may be prepared from random urethane oligomer compositions including fluorinated alkyl ether segments, in which the oligomers may be terminated with amino groups and subsequently reacted with epoxy including monomers or oligomers.
