Abstract
A composition and process for preparing a sprayable solution containing perfluoroalkoxy (PFA) resin. Components of the solution include an aromatic solvent, a binding agent, a surface active agent, and water in addition to the PFA. The solution can generally be sprayed from conventional spraying apparatus at ambient temperatures. A desired use is as a mold release agent, or as a corrosion, wear, or abrasion-resistant coating.
Claims5
A sprayable perfluoroalkoxy resin solution, comprising by weight:
- from about 5 to about 25 parts of an aromatic solvent, and wherein said aromatic solvent is xylene or toluene,
- from about 3 to about 15 parts of a binding agent, and wherein said binding agent is glycerine,
- from about 2 to about 13 parts of a surface active agent, and wherein said surface active agent is an alkyl phenol ethylene oxide condensate product having from 12 to 15 moles of ethylene oxide,
- from about 11 to about 70 parts of water, and
- from about 10 to about 50 parts of a perfluoroalkoxy resin.
