Aqueous delivery system for low surface energy structures

摘要

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.

主权项

1. A method of applying an aqueous mixture to a low surface energy material comprising:
providing an aqueous mixture comprising an emulsion comprising at least one water insoluble alcohol having five or more carbon atoms in the longest continuous chain in an amount from 1.2% to about 30% by weight of the aqueous mixture, and at least one non-fluorinated surfactant; providing a low surface energy material having a surface energy of less than about 40 dynes/cm; applying the aqueous mixture to the surface of the low surface energy material; and wetting the low surface energy material in less than 30 seconds with the aqueous mixture, wherein said aqueous mixture is free of fluorinated surfactants.
