Claims19
A coating formulation comprising:
- a base coat including a copolymer of a first tetrahydrofurfuryl acrylate monomer and a second monomer including a functional group amenable to further derivatization and a plurality of reactive moieties, and
- a top coat including a hydrophilic polymer containing less than two reactive moieties per molecule.
A coating formulation comprising:
- a base coat including a copolymer of a first tetrahydrofurfuryl acrylate monomer and a second monomer including a functional group amenable to further derivatization and a plurality of reactive moieties, and
- a top coat including a hydrophilic polymer containing less than two reactive moieties per molecule,
- wherein the hydrophilic polymer has a molecular weight between about 1,000 amu to about 40,000 amu, and
- wherein the coating formulation reduces the maximum dynamic friction force by about 50% or more on a surface coated with the coating formulation as compared to the surface prior to being coated with the coating formulation.
