This invention relates to novel non-isocyanate siloxane-modified glycidol carbamate (GC) resins and coating compositions containing them. The non-isocyanate siloxane modified GC resins of the invention comprise the reaction product of at least one organic polyisocyanate, glycidol, and at least one bis(hydroxyl alkyl)-terminated polydimethylsiloxane. The coating compositions of the invention comprise at least one non-isocyanate siloxane modified GC resin of the invention and at least one curing agent. The invention also relates to methods of making the resins of the invention and coatings containing them. The invention also relates to a fouling-release (FR) coating system comprising the coating compositions of the invention and methods of applying said FR coating systems to substrates. The invention also relates to articles of manufacture comprising a coating composition of the invention and a method of making such articles.

A substrate with a switchable surface has been developed that can rapidly switch its surface character such as between two distinct liquid-repellent modes: (1) a superhydrophobic mode and (2) a slippery mode. Such surfaces have demonstrated adaptive liquid repellency and water harvesting capabilities.

An easy-cleaning coating, an easy cleaning coating having anti-fogging properties, and an easy-cleaning, anti-reflective coating.

An organosiloxane composition and the use of such compositions is provided. The organosiloxane composition comprises (a) 20-55 wt. % of at least one polymerization-effective polymer bearing two or more silicon atoms; (b) 24-60 wt. % of a first filler of average particle size from 0.1 m to 10 m; (c) optionally a second filler; (d) a crosslinking agent; and (e) a catalyst. The use of the first filler having that size range and present in this amount provides improved dirt pick up resistance to films and coatings formed from the compositions.

The invention relates to a hydrolysable binder based on an ABAB type polysiloxane copolymer suitable for the preparation of coating compositions with an improved anti-adhesive and/or dirt-repellent surface.
