Assignee:

SUN CHEMICAL CORPORATION - Parsippany NJ

International Classification:

C09D 5/16
C09D 11/38
C09D 133/08
C09D 11/101

Abstract:

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.

Abstract:

Provided are energy curable inks and coatings, comprising acrylated silicone and monomers/oligomers containing acrylate functional groups, that have improved adhesion on flexible substrates, such as non-chemical coated flexible films at fast speed. The energy curable inks and coatings have a robust slide angle upon surface abrasion, resulting in a reduction of the slippage of printed substrates, such as bags, when piled on top of each other. Also provided are raw material screening methods for quantifying acrylate group concentration, which is used to adjust the ink or coating formula to improve the cure at the surface and bottom and to improve tape adhesion and MEK resistance of energy cured inks and coatings.
