Fluorinated coatings with lubricious additive

摘要

Fluorinated coatings having a lubricious additive, articles with the fluorinated coatings, and methods of making articles with the fluorinated coatings are provided. More specifically, the fluorinated coatings are prepared from a curable coating composition that includes both a fluorinated silane and a fluorinated polyether oil. The curable coating composition is typically applied adjacent to a siliceous substrate and then cured. The resulting cured articles can have an outer surface that has a good tactile response, that is abrasion resistant, that is easy to clean, or a combination thereof.

1. A curable coating composition comprising:
1) a fluorinated silane of Formula (I)
F(CF(CF3)CF2O)nCF(CF3)—CH2O—CH2CH2CH2Si(R1)3-x(R2)x   (I) wherein
R1 is hydroxy or a hydrolyzable group;R2 is a non-hydrolyzable group;n is an integer in a range of 4 to 100;x is equal to 0, 1, or 2; and 2) a fluorinated polyether oil having zero or one hydrogen atoms per molecule, wherein the curable coating composition is free of silica particles.
