Marine coatings including cationic polymers hydrolyzable to nonfouling zwitterionic polymers, coated marine surfaces, and methods for making and using the marine coatings.

A coating composition for application to a subsea component or structure has cellulose acetate an amount of approximately 47% by weight of the total composition, diisooctyl phthalate in an amount of approximately 17% by weight of the total composition, a fatty acid ester in an amount of approximately 23% by weight of the total composition, a vegetable oil in an amount of approximately 8% by weight of the total composition, a stabilizer and a silica amorphous in which the stabilizer and the silica amorphous are in amount of approximately 5% by weight of the total composition. The stabilizer can be either titanium dioxide or aluminum dioxide. The vegetable oil is canola oil.

A method of protecting a part of a surface of an aircraft against contamination with insect residues and/or against icing is described. The method includes the following steps: a) coating the part of the surface to be protected with a coating that can, within a period of 3 hours from take-off of the aircraft and in normal flying conditions, reduce the adhesion to the part of the surface to be protected until detachment occurs on the basis of (i) temperature change and/or (ii) UV radiation and/or (iii) addition of a decomposing component and/or (iv) difference in air humidity, and b) exposing the part of the surface to be protected to (i) a temperature change and/or (ii) UV irradiation (iii) and/or addition of a decomposing component and/or (iv) a difference in air humidity, so that the coating together with any contaminants and/or icing thereon detaches.

The present disclosure describes a strategy to create self-healing, slippery liquid-infused porous surfaces (SLIPS). Roughened (e.g., porous) surfaces can be utilized to lock in place a lubricating fluid, referred to herein as Liquid B to repel a wide range of materials, referred to herein as Object A (Solid A or Liquid A). SLIPS outperforms other conventional surfaces in its capability to repel various simple and complex liquids (water, hydrocarbons, crude oil and blood), maintain low-contact-angle hysteresis (<2.5), quickly restore liquid-repellency after physical damage (within 0.1-1 s), resist ice, microorganisms and insects adhesion, and function at high pressure (up to at least 690 atm). Some exemplary application where SLIPS will be useful include energy-efficient fluid handling and transporation, optical sensing, medicine, and as self-cleaning, and anti-fouling materials operating environments.

Marine coatings including cationic polymers hydrolyzable to nonfouling zwitterionic polymers, coated marine surfaces, and methods for making and using the marine coatings.

Provided is a stabilized slurry composition having enhanced barrier properties. The slurry includes a pigment having a BET surface area of greater than 15 m.sup.2/g and a composite of a microcrystalline cellulose and carboxymethyl cellulose. The slurry can be used to formulate barrier coatings to be applied to the surface of a paper or paperboard product to enhance and improve the barrier properties of the product.

Disclosed are waterproofing compositions and waterproofing articles, such as waterproofing membranes comprising such waterproofing compositions. The waterproofing composition can include a hydrophobic binder and a swellable filler. The hydrophobic binder can include at least one of (i) a polymer modified asphalt comprising an asphalt and a polymer additive; (ii) a hot melt adhesive; and/or (iii) a thermoplastic polymer. The swellable filler can include at least one of (a) at least 15 wt. % and no greater than 85 wt. % of a swellable clay, and/or (b) at least 0.1 wt. % and no greater than 70 wt. % of a super absorbent polymer, wherein the amounts in wt. % are based on a total weight of the waterproofing composition.

A release agent and method of use for preventing the adhesion of materials to equipment in various industries including construction, mining, and asphalt. The release agent can include oil, surfactant, and in increased level of free fatty acids that can combine with alkali and/or alkaline earth metals in the materials to form a metal/fatty acid salt that prevents adhesion and material build up.

A photosensitive epoxy resin composition, comprising at least: (A) an epoxy resin comprising two or more epoxy groups in one molecule; (B) a cationic polymerization catalyst; (C) a silicone compound comprising one or more alkylsiloxane groups in one molecule; and (D) an alcohol or phenol compound comprising a long chain alkyl group having 9 to 18 carbon atoms.

A superhydrophobic anti-fouling crayon comprises a composition of capsaicin, wax, polydimethylsiloxane (PDMS), polytetrafluoroethylene (PTFE), and triglyceride, where the crayon is water insoluble, superhydrophobic, and transparent to electronic sensor and antennae signals. The crayon is rubbed onto the marine surface such that a layer of the composition of the crayon is applied thereto to produce a durable coating that inhibits fouling.
