Abstract: The present invention is directed to a phosphated epoxy resin comprising at least one terminal group comprising a phosphorous atom covalently bonded to the resin by a carbon-phosphorous bond or by a phosphoester linkage; and at least one carbamate functional group. The present invention is also directed towards aqueous resinous dispersions comprising the phosphated epoxy resin, methods of coating a substrate, coated substrates, and methods of making a phosphated epoxy resin.

Abstract: Sulfur-containing poly(alkenyl) ethers can be incorporated into the backbone of polythioether prepolymers and can be used as curing agents in thiol-terminated polythioether prepolymer compositions. Cured sealants prepared using compositions containing sulfur-containing poly(alkenyl) ether-containing polythioether prepolymers and/or sulfur-containing poly(alkenyl) ether curing agents exhibit improved physical properties suitable for use in aerospace sealant applications.

Abstract: Luminescent tools for applying or removing sealants and adhesives are disclosed. The tools may be provided in the form of spatulas, scrapers, spreaders, smoothers and the like having surfaces that contact the sealant or adhesive material during application or removal. The tools or components thereof are made of load-bearing polymeric materials including a luminescent material. The luminescent tools may be seen and recovered when used in dark environments, such as during aircraft fabrication operations.

Abstract: A solar reflective coating composition includes: a film-forming resin; a plurality of near-IR transparent pigments dispersed in the film-forming resin, the plurality of near-IR transparent pigments including a first perylene pigment and a second perylene pigment different from the first perylene pigment; and a near-IR reflective pigment dispersed in the film-forming resin, the near-IR reflective pigment different from the first perylene pigment and the second perylene pigment. When formed into a cured coating over a substrate, the cured coating exhibits an off-white or grey color. The solar reflective coating composition is substantially free of carbon black. The present invention is also directed to a substrate having a surface at least partially coated with a solar reflective coating composition and a method of preparing a low weight aerospace component.

Abstract: Disclosed are methods for making a cured sealant. The methods include depositing an uncured sealant composition on a substrate and exposing the uncured sealant composition to actinic radiation to provide a cured sealant. The uncured sealant composition includes a thiol-terminated polythioether, a polyene comprising a polyvinyl ether and/or a polyallyl compound, and a hydroxy-functional vinyl ether. Related sealant compositions are also disclosed.
