SUPERHYDROPHOBIC UV CURABLE COATING

摘要

The present invention describes hydrophobic hybrid solvent-based and energy curable compositions that include monomers and/or oligomers that have a composite molar average functionality greater than 1; optionally a photoinitiator; hydrophobic nanoparticles with particle size 1 nm to 30 μm; and one or more solvents. The reaction product of the monomers and/or oligomers is a polymer having greater than 1% mole% alkylenic reactive sites of unsaturation. The surfaces of the compositions are hydrophobic when dried and cured. In certain embodiments, the compositions are super-hydrophobic. The compositions further maintain robust hydrophobicity after aging at elevated temperature.
