Curable compositions comprising 1,1-di-activated vinyl compounds are provided herein. Also provided are coatings formed from 1,1-di-activated vinyl compounds. Also provided are processes for coating substrates and articles. Curable compositions including 1,1-di-activated vinyl compounds that function as crosslinking agents are described.

Curable compositions containing 1,1-di-activated vinyl compounds and related coatings and processes

Disclosed are particles that have an exterior surface coated with a thin polymeric coating, such as a coating that includes a sulfur-containing polymer. Also disclosed are compositions, such as fuel-resistant sealant and coating compositions, which include such particles. Aerospace vehicles having an aperture at least partially sealed with a sealant deposited from such a sealant composition are also disclosed.

Lightweight particles and compositions containing them

Controlled release polyurea microcapsules can be prepared from a combination of polyisocyanates using emulsion polymerization. Encapsulated catalysts prepared using the polyurea microcapsules can be used to control the cure rate of coatings and sealants.

Delayed cure micro-encapsulated catalysts

Sulfur-containing polymeric particles having a high sulfur content can be prepared using emulsion polymerization. The sulfur-containing polymeric particles are useful in aerospace coatings and sealants.

Sulfur-containing polymeric particles and compositions

Low density particles that have an exterior surface coated with a thin polymeric coating of an aminoplast can be used in aerospace sealants to reduce the specific gravity of a sealant.

The present invention is directed to curable film-forming compositions comprising: (a) a polymeric binder comprising: (i) a polysiloxane having reactive functional groups and in which is dispersed protonated silica particles having an average particle size of 2 to 20 microns; and (ii) optionally, at least one additional polymeric resin different from the polysiloxane (i), having reactive functional groups; and (b) a curing agent containing functional groups that are reactive with the reactive functional groups of (i) and/or (ii). After application to a substrate as a coating and after curing, the curable film-forming composition demonstrates an initial 85&#xb0; gloss of less than 30 and an increase in 85&#xb0; gloss of no more than 10 gloss units when subjected to various ABRASION TEST METHODS as defined herein. Also provided is a method of improving burnish resistance of a substrate using the curable film-forming compositions of the present invention.

Compositions comprising thiol-terminated sulfur-containing prepolymers, curing agents reactive with the thiol-terminated sulfur-containing prepolymers, and ionic liquid catalysts, useful in aerospace sealant applications are disclosed. The use of ionic liquid catalysts provides curable sealant compositions having an extended working time and a rapid cure rate.

Ionic liquid catalysts in sulfur-containing polymer compositions

Compositions comprising Michael acceptor-terminated sulfur-containing prepolymers, thiol-terminated sulfur-containing prepolymers, and e phosphine catalysts useful in aerospace sealant applications are disclosed. The compositions exhibit extended pot life, cure rapidly following activation, and provide cured sealants having improved properties useful in aerospace sealant applications.

Phosphine-catalyzed, michael addition-curable sulfur-containing polymer compositions

Particles that have an exterior surface coated with a thin polymer coating, such as a coating that includes a sulfur-containing polymer can be used as lightweight fillers in compositions, such as fuel resistant sealant and coating compositions. The compositions can be used to seal apertures on aerospace vehicles.

Rapidly curable electrically conductive clear coatings are applied to substrates. The electrically conductive clear coating includes to clear layer having a resinous binder with ultrafine non-stoichiometric tungsten oxide particles dispersed therein. The clear coating may be rapidly cured by subjecting the coating to infrared radiation that heats the tungsten oxide particles and surrounding resinous binder. Localized heating increases the temperature of the coating to thereby thermally cure the coating, while avoiding unwanted heating of the underlying substrate.

Compositions comprising sulfur-containing polymers such as polythioethers, Michael acceptors, and controlled release amine catalysts employing Michael addition curing chemistries useful in aerospace sealant applications are disclosed. The compositions exhibit extended pot life and the rate of curing can be tailored for specific applications.

Controlled release amine-catalyzed, Michael addition-curable sulfur-containing polymer compositions

Compositions useful in aerospace sealant applications comprise sulfur-containing polymers such as polythioethers and polysulfides and are cured using Michael addition reactions. Compositions employing Michael addition curing chemistries include sulfur-containing adducts comprising terminal Michael acceptor groups. In particular, the sulfur-containing adducts include terminal 1-(ethylenesulfonyl)-n-(vinylsulfonyl)alkanol groups.
