Abstract: Finishing composition substantially free of non-volatile silicone materials and comprises a mixture of abrasive particles and an emulsion, which comprises water, a volatile siloxane, and a lubricant.

Abstract: Coatings are provided with very low surface energies provided by fluorine and/or silicone moieties. Aqueous dispersions of externally chain extended polyurethane compositions terminated by hydrolyzable and/or hydrolyzed silyl groups and containing dispersing or emulsifying groups, particularly carboxyl groups are provided. Also polyurethane dispersions which are substantially organic solvent free which cure to water and solvent resistant, tough, scratch resistant, preferably light stable polyurethane films are provided. Such films are useful as anti-fouling marine coatings. The compound RfR′fCFCOOCH2C(R)(CH2OH)2 is provided.

Abstract: This invention provides aqueous dispersions of externally chain extended polyurethane compositions terminated by hydrolyzable and/or hydrolyzed silyl groups and containing anionic solubilizing or emulsifying groups, particularly carboxyl groups. The invention also provides methods of making both anionically and cationically stabilized polyurethane dispersions. This invention further provides polyurethane dispersions which are substantially organic solvent free, (e.g. less than about 7 weight percent organic solvent) which cure to water and solvent resistant, tough, scratch resistant, preferably light stable (non-yellowing) polyurethane films. Such films are particularly useful as coatings for wood substrates, including wood floorings, furniture, and marine surfaces.

Abstract: A spray assembly including a venturi type spray nozzle, a valve attached to the spray nozzle, a reservoir adapter that can engage a reservoir containing a liquid coating material to be sprayed, and a flexible hose between tile reservoir adapter and the valve. The outer surface texture of material being coated can be adjusted using the valve which is useful in matching the surface texture of chip resistant coatings and undercoatings on an automobile, and the hose allows the operator to spray material onto a substrate from any orientation of the spray nozzle which facilitates coating locations such as the lower portions of panels or in wheel wells and trunks. A valve passageways is shaped to facilitate fine adjustment of the air/coating material ratio when small amounts of material are being delivered, and the valve includes an air purge to remove material from the valve and nozzle when the valve is shut off.

Abstract: The present invention relates to an article comprising a substrate which has coated thereon a photopolymerizable epoxy composition containing a plurality of epoxides including at least one selected from the group consisting of bisphenol A epoxides and cycloaliphatic epoxides, and at least one aliphatic epoxide, from about 0.1% to about 2% of at least one organometallic cationic initiator capable of initiating polymerization at wavelengths of from about 200 to about 600 nm, and optionally at least one accelerating agent. The article can be a flexible tape backing or a chip-resistant paint.
