The present invention relates to a formulation technology that forms an omniphobic, slippery gel coating The formulation technology makes use of the cross-linking between two hydrophobic polymer reagents, solvated in a hydrophobic polymer lubricant, as they are combined and deposited on a substrate.

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.

A coating composition comprising: (a) at least one coating agent comprising a perfluoropolyether-modified al-kyloxysilane polymer; and (b) a carrier composition comprising monochloro, trilluoropropene, wherein the carrier is present in an amount effective to at least partially solvate or at least partially emulsify the coating agent. Such compositions may optionally contain one or more other co-carriers or additives. Also disclosed are methods of coating substrates, in particular substrates having a hard surface such as ceramics or glass, to render them water, oil and/or dirt repellent.

The disclosed technology provides thermoplastic polyurethane compositions having non-leaching antimicrobial properties while still maintaining good physical properties, methods of making the same, and articles, including medical devices, made from such compositions. The disclosed technology includes a process of making an antimicrobial polymer composition, where the process includes mixing an antimicrobial additive into a polymeric material; wherein said polymeric material comprises a polymeric backbone made up of urethane linkages derived from a polyisocyanate and a polyol; and wherein said mixing occurs under conditions that result in the breaking of a minority of said urethane bonds resulting in reactive isocyanate groups; and wherein two or more of said reactive isocyanate groups react with said antimicrobial additive to covalently bond said antimicrobial additive into the polymeric backbone of said polymeric material; resulting in an antimicrobial polymer composition.

Systems and methods for sealing concrete are provided. An exemplary multilayer concrete sealant includes a first layer disposed over a concrete surface, wherein the first layer includes an epoxy nanocomposite, and a second layer disposed over the epoxy nanocomposite, wherein the second layer includes a polyurethane microcomposite.

The present application discloses a method of forming a hydrogel-coated substrate, wherein the hydrogel has antifouling and antimicrobial properties. The method comprises applying an aqueous pre-hydrogel solution to a substrate, polymerizing the aqueous pre-hydrogel solution, thereby forming a coated substrate having a conformal hydrogel coating and a non-conformal hydrogel coating, contacting the coated substrate with a swelling agent, and removing the non-conformal hydrogel coating from the coated substrate, thereby leaving the conformal hydrogel coating on the substrate to form the hydrogel-coated substrate. The aqueous pre-hydrogel solution comprises a monomer with antimicrobial activity, a monomer with antifouling activity, and either a polymer, oligomer, or macromer which, when polymerized together, form a hydrogel. Also disclosed is a coated substrate and a hydrogel coating.

Provided is an anti-fingerprint coating compound including a top portion, a linker, and an end portion, in which the top portion includes two or three perfluoropolyether moieties, the linker linking the top portion to the end portion is a trivalent or tetravalent linking group, and the end portion includes a siloxane moiety.

A water- and oil-repellent agent contains cellulose nanofibers, a compound having at least one functional group of an oxazoline group, a carbodiimide group, an epoxy group and an isocyanate group, as a crosslinking agent, and a perfluoroalkyl compound.

An antimicrobial formulation that can be directly added into a composition or onto a surface of a composition (e.g., forming a surface coating on a composition or device). The antimicrobial formulation includes sodium pentaborate, di-sodium tetraborate decahydrate, titanium diborite, titanium borate, sodium pyrithione, zinc pyrithione, benzhetonium chloride, or any combination thereof.

A microbe-resistant coating composition or paint including an antimicrobial agent is described. The antimicrobial agent is an inorganic bismuth-containing compound, and may be used in conjunction with other bismuth-containing compounds or other biocidal agents or methods. A method of treating an electrodeposition system for bacterial and/or fungal contamination is also described by adding an antimicrobial agent to at least a portion of the electrodeposition system.
