Abstract
The invention features an article comprising a reactive substrate that forms a covalent or hydrogen bond with a surface layer. The surface layer of the article comprises the reaction product of at least one monoterminated (per)fluoropolyether (meth)acryl compound and at least one monomer or oligomer having at least two (meth)acryl groups.
Claims22
An article comprising
- a reactive substrate selected from the group consisting of:
- leather, paper, masonry, concrete, natural stone, man-made stone, grout, metal sheets and metal foils, polyvinylchloride, and paint, and
- a surface layer comprising the reaction product of at least one monoterminated (per)fluoropolyether (meth)acryl compound and at least one non-fluorinated monomer or oligomer having at least two (meth)acryl groups;
- wherein the reactive substrate forms a covalent or hydrogen bond with the surface layer.
