  • Aqueous delivery system for low surface energy structures
    Patent number: 9018264
    Abstract: An aqueous delivery system is described including at least one surfactant and at least one water insoluble wetting agent. Further described are low surface energy substrates, such as microporous polytetrafluoroethylene, coated with such an aqueous solution so as to impart a change in at least one surface characteristic compared to the surface characteristics of the uncoated low surface energy substrate.
    Type: Grant
    Filed: March 14, 2013
    Date of Patent: April 28, 2015
