The embodiments herein relate to a substrate coated with a multi-layer coating system including: optionally a primer layer applied to the substrate and deposited from a primer coating composition; a tie-coat layer applied to the substrate or to the optional primer layer, deposited from a tie-coat composition including a binder polymer obtainable by copolymerizing a mixture of ethylenically unsaturated monomers, the binder polymer having curable alkoxysilyl functional groups. The substrate can include a topcoat layer applied to the tie-coat layer, and deposited from a non-aqueous liquid foul release coating composition including a curable resin system including i) a curable polymer and optionally ii) a curing agent and/or a catalyst, where the non-aqueous liquid foul release coating composition is essentially free of a curable polysiloxane.

A self-cleaning external with a self-cleaning aerodynamic surface configured to extract at least some of the oxygen present in the atmosphere in contact with the aerodynamic surface so as to at least partially deprive a haemolymph of the insect residue, present on the aerodynamic surface after being hit by insects, of oxygen. Also, a vehicle with at least one such self-cleaning aerodynamic surface.

The present invention relates to a coating film forming composition, in which a coating film formed by the coating film forming composition has a water contact angle, after a surface was washed with water, of 25 or less, and a water content, after impregnation with water at 25 C. for 2 hours, of 110% or less.

The invention relates to a crosslinkable fluorinated urethane compound having at least one ethylenically unsaturated functional group. Such compounds are useful as coatings additives such that, when the coating is applied to a substrate, the additive compound is allowed to first migrate to the surface and subsequently crosslink to form a durable oil-, dirt-, and water-repellent surface.

The present invention relates to compositions and processes in the field of self-cleaning system using digestive proteins. One composition includes a substrate, a digestive protein capable of decomposing a stain molecule, and a linker moiety bound to both said digestive protein and said substrate. The processes include binding a substrate to a surface and forming a linker moiety between a digestive protein and said substrate.

A controlled-release material sensitive and response to fouling organisms for an antifouling agent includes an encapsulating precursor and a crosslinking agent. A hyaluronic acid/polyL-lysine nano-shell controlled-release material is prepared by an alternating layer-by-layer self-assembly of hyaluronic acid and poly-L-lysine, and a polypropylene ammonium chloride/poly-L-glycine nano-shell controlled-release material is prepared by an alternating layer-by-layer sell-assembly of polypropylene ammonium chloride and poly-L-glycine. The crosslinking agent is composed of 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride and N-hydroxythiosuccinimide. Based on the specific catalytic hydrolysis characteristic of fouling organism extracellular proteases on the controlled-release material, the purpose of adjusting the release of antifouling agents adaptively with the change of fouling organisms in off-season/peak-season can be achieved, prolonging the service life of the antifouling coatings.

An anti-fouling coating comprising a polymeric compound, wherein a backbone of the polymeric compound is covalently bonded to a quorum sensing inhibitor, and wherein the anti-fouling coating has substantially no bactericidal activity, the quorum sensing inhibitor is substantially non-leaching from the anti-fouling coating, or both.

A filtration membrane coating comprising a hydrophilic polymer, a surfactant, and one or more charged compounds, each containing one or more sulfonate functionalities and one or more linkable functionalities selected from the group consisting of amine, monochlorotriazine, and dichlorotriazine. The hydrophilic polymer and surfactant form a thin primer layer which is also superhydrophilic. The primer layer improves flux, and enables improved adhesion of the one or more charged compounds, which form a charged dye layer on top of the primer layer when enhances rejection of charged divalent ions. The coating can be applied while the membrane is packaged in its final form, such as in a spiral wound or other configuration.

An aqueous dispersion containing BIT and IPBC prepared using nonionic and anionic surfactants exhibits both chemical and physical stability and is suitable for use as a single product which is capable of imparting to a coating composition a high level of resistance against attack by a broad spectrum of organisms, including bacteria, fungi and algae, in both the wet-state and dry film-state.

Water-based compositions that are resistant to dirt pickup, efflorescence, tannin bleed-through and surfactant leaching are described. The water-based composition includes a latex or water-dispersible polymer and a non-VOC UV-VIS (preferably, ultraviolet) absorber as a dirt pickup resistance additive. Methods of making water-based compositions including a non-VOC UV-VIS absorber as an additive are also described.
