Abstract: A decorated particle comprises a single inorganic particle core having an uneven outer surface with a plurality of crevices and an average particle diameter of 20 to 150 microns. A binder retaining decorating particles is disposed on at least a portion of the outer surface of the inorganic particle core and fills the crevices. The decorating particles have an average particle diameter of 0.05 to 10 microns. A method of making decorated particles is also disclosed.

Abstract: A composition is described comprising a ring opening metathesis polymerization catalyst or precatalyst thereof; and an unreactive dispersant having a viscosity at 25° C. of at least 10 Pa·sec at a shear rate of 1 1/sec. Also described is a cartridge (e.g. or a dispensing and mixing apparatus) comprising such composition. The cartridge typically comprises a first chamber comprising unpolymerized cyclic olefin; and a second chamber comprising the catalyst and dispersant. Also described are compositions including two-part compositions and methods of bonding a substrate.

Abstract: Curable compositions include a non-aromatic epoxy-functional epoxy resin adduct, a non-aromatic epoxy resin, and a non-aromatic anhydride-based curing agent. The epoxy resin adduct is the reaction product of a reaction mixture including a polyfunctional thiol and a poly functional epoxy resin. The cured composition has an Izod Impact Test (Notched Izod) test method (ASTM D256) value of at least 40 J/m and is color stable such that upon exposure to an acid bath in accordance with the Acid Bath Test Method, exhibits a ΔE 94 color change of less than 1.
