The present invention is directed towards curable film-forming coating compositions comprising metal particles; an alkaline earth metal compound comprising an alkaline earth metal oxide, an alkaline earth metal carbonate, an alkaline earth metal hydroxide, an alkaline earth metal sulfate, an alkaline earth metal monocarboxylate, an alkaline earth metal phosphate, or combinations thereof; and an organic film-forming binder. Also disclosed are methods of making curable film-forming coating compositions, methods of coating substrates, and coated substrates resulting therefrom.

Coating compositions having improved corrosion resistance

A curable coating composition includes: (a) a binder having a film-forming resin with at least two functional groups, and (ii) a curing agent reactive with the functional groups of the film-forming resin; and (b) solid vulcanized rubber particles that are unreactive with the binder. The curable coating composition is a solid particulate powder coating composition. Multi-layer coating systems, coated substrates, and methods of preparing the curable coating composition are also disclosed.

Impact resistant coating compositions, multi-layer coating systems, and substrates at least partially coated with such compositions

The present invention relates to a substrate having (a) a first material applied to at least a portion of the substrate, and (b) a coating layer deposited from a powder coating composition including a film-forming resin, and optionally a crosslinker that is reactive with the film-forming resin, in direct contact with at least a portion of the substrate to which the first material has been applied. The first material is (i) a catalyst that catalyzes cure of the powder coating composition, (ii) a component reactive with the film-forming resin and/or the crosslinker of the powder coating composition, and/or (iii) a rheology modifier.

Coated substrates and methods of preparing the same

A curable coating composition includes: (a) a binder having a film-forming resin with at least two functional groups, and (ii) a curing agent reactive with the functional groups of the film-forming resin; and (b) solid vulcanized rubber particles that are unreactive with the binder. The curable coating composition is a solid particulate powder coating composition. Multi-layer coating systems and methods of preparing the curable coating composition are also included.

Impact resistant coating compositions

Polyoxazoline-containing compositions cured in the presence of an onium salt catalyst are disclosed.

Polyoxazoline-containing compositions catalyzed with onium salt

A powder coating composition grindable at non-cryogenic temperatures includes: (a) a first polymer having a number average molecular weight (Mn) of more than 1,000 and a Tg of at least 40&#xb0; C.; (b) a second polymer having a Tm of at least 100&#xb0; C.; and optionally (c) a cross-linker. The first polymer and the second polymer are different from one another, and each of the first and second polymers have less than 25 wt % fluorine-containing monomeric units, with wt % based on the total weight of the monomeric units in each polymer. Upon grinding at a temperature above 4&#xb0; C. the coating composition has an average particle size from 15 to 150 microns. Further coating compositions, methods of preparing coating compositions, coating systems, and substrates coated with a powder coating composition are also disclosed.
