▎ 摘  要

NOVELTY - A composition for a coating comprises epoxy-functional monomers; a diluent; and a sufficient amount of a hydrophobicity-modifying additive that is reactive in an epoxide polymerization to provide a coating formed from the composition having a contact angle of greater than or equal to 90 degrees when measured with an Ossila Goniometer following ASTM D7334-08 (2013). USE - A composition for a coating and for forming a coating on a substrate which is surface of marine equipment or marine vessel, such as boat or ship (all claimed). ADVANTAGE - The composition that can be used to form an epoxy-based coating exhibits anti-fouling/foul-releasing properties, improved corrosion resistance, and increased mechanical strength or bending strength. The coatings allow ship-owners to enjoy the benefits of a hard cleanable surface while obtaining fuel savings from its foul release properties without leaching biocides or silicone oils. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) reaction product comprising the composition and a hardener; (2) kit comprising a composition for a coating and instructions for use, or instructions ofr use with hardener; (3) additives composition for use in forming a coating, comprising a sufficient amount of a hydrophobicity-modifying additive that is reactive in an epoxide polymerization for forming a coating having a contact angle of greater than or equal to 90 degrees ; and a sufficient amount of a wear-inhibiting additive for forming a coating having improved corrosion resistance of greater than or equal to 1000 hours when measured by salt fog resistance, an increased mechanical strength with a D-shore hardness of a greater than or equal to 40D, or bending strength of greater than or equal to 10 mm when measured by a cylindrical bed test; (4) kit comprising the additives composition and instructions for adding the additives to a composition for a coating; (5) method of forming a composition for a coating, which involves mixing a hydrophobicity-modifying additive into a first mixture comprising epoxy-functional monomers and a diluent; and forming the composition for a coating; (6) forming a composition for a coating which involves mixing a dispersant into a first mixture comprising a first epoxy-functional monomer and diluent to form a second mixture; mixing a wear-inhibiting additive into the second mixture to form a third mixture; mixing a rheological additive into the third mixture to form a fourth mixture; optionally mixing a first amphiphilicity-modifying additive into the fourth mixture; mixing a hydrophobicity-modifying additive into the fourth mixture to form a fifth mixture; mixing a second amphiphilicity-modifying additive into the fifth mixture to form a sixth mixture; optionally mixing a defoamer into the first or second mixture, or optionally mixing a defoamer into the fifth or sixth mixture; optionally mixing a mixture comprising a second epoxy-functional monomer and diluent into the the fifth or sixth mixture; and forming the composition for a coating; and (7) forming a composition for a coating which involves mixing epoxy-functional monomers and a diluent to form a first mixture; mixing into the first mixture a hydrophobicity-modifying additive, a wear-inhibiting additive, a dispersant, an amphiphilicity-modifying additive, a defoamer, and/or a rheological additive; and forming the composition for a coating.
