Abstract
Highly water repellent coated articles may be made by applying to a substrate a coating having dispersed therein or sprinkled thereon partially or fully fluorinated polymer microparticles. The coating includes a partially fluorinated hexafluoropropylene copolymer binder in a nonfluorinated solvent that dissolves the binder and does not dissolve the microparticles. The coating is heated sufficiently to bond the microparticles to the binder but not so much as to cause the receding water contact angle for the coating to fall below 80°.
