    Abstract: Provided is a curative part usable in a two-part curable composition. The curative part includes a liquid amine; a heterogeneous dispersant; and core-shell rubber particles having an elastomeric core and a (meth)acrylic shell. The core-shell rubber particles and the heterogeneous dispersant can be collectively shear-dispersed in the liquid amine such that the core-shell rubber particles are substantially non-aggregated and the curative part is phase-stable over a period of at least 3 months at ambient temperature. Advantageously, large amounts of core-shell rubber particles can thus be incorporated into a cured resin matrix, which can afford significantly enhanced impact performance.

    Abstract: A two-part adhesive is provided comprising: A) a curative part comprising: i) an epoxy curative; and ii) a reaction intermediate which is the reaction product of a suspension of core/shell rubber nanoparticles in a liquid epoxy resin and an excess of the epoxy curative; wherein the curative part comprises greater than 1.1 wt % core/shell rubber nanoparticles; and B) an epoxy part comprising: iii) a liquid epoxy resin; and iv) greater than 9.1 wt % core/shell rubber nanoparticles. In some embodiments, the epoxy part additionally comprises greater than 5.1 wt % solid epoxy resin, such as, e.g., triglycidyl ether of trisphenol-methane. In some embodiments, the sum of the wt % solid epoxy resin and the wt % core/shell rubber nanoparticles in the epoxy part is greater than 41.0%. In some embodiments, the sum of the wt % solid epoxy resin and the wt % core/shell rubber nanoparticles in the mixed adhesive is greater than 26.0%.

    Abstract: A method of providing an easy-clean, water-sheeting coating on a substrate includes: abrading a surface of a substrate using an abrasive article to provide an abraded surface having a surface roughness R?a#191 in a range of from 100 nm to 3500 nm, contacting a coatable composition with the abraded surface, and removing water from the coatable composition. The coatable composition comprises silica nanoparticles and has a pH of 7.5 or less. A kit including the abrasive article and the coatable composition is also disclosed.

    Abstract: An adhesion promoter, a curable composition containing the adhesion promoter, a cured composition formed from the curable composition, and an article containing the cured composition are provided. The adhesion promoter, which is formed by reacting a polyepoxide with a mercaptosilane that has a hydrolyzable silyl group, has at least one epoxide group and at least one hydrolyzable silyl group. The epoxide groups allow incorporation of the adhesion promoter into the polymeric matrix of the cured composition and the hydrolyzable silyl groups allow bond formation with various substrates.
