Abstract
Hydrophobic coating compositions are provided as are processes to coat articles with the compositions. Extremely hydrophobic coatings are provided by the compositions. Compositions that include perfluorohexyl(meth)acrylate and a branched or high Tg monomer are provided as are articles coated with the polymerization product of the composition. Methods are also provided for forming hydrophobic coatings on articles.
Claims26
A coating composition comprising a perfluorohexyl(meth)acrylate and a branched or high Tg monomer, the coating composition being formulated to be polymerizable to form a coating surface having a surface area populated with 30% by area or more trifluoromethyl groups and a surface energy of about 22 dynes/cm or lower at 20° C.
A laboratory vessel, said vessel comprising a vessel material having a surface intended to contact a liquid and a coating applied to at least a portion of the surface, wherein said coating comprises the polymerization product of a perfluorohexyl(meth)acrylate and a branched or high Tg monomer, the coating comprising a coating surface having a surface area populated with 30% by area or more trifluoromethyl groups and a surface energy of about 22 dynes/cm or lower at 20° C.
