International Classification:

C08G 59/50
C09J 163/00
C08K 5/372
C08G 59/62

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.

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:

The present disclosure provides a polymeric material including a polymerized reaction product of a polymerizable composition including components and has a solids content of 90% or greater. The components include a uretdione-containing material including a reaction product of a diisocyanate reacted with itself; a first hydroxyl-containing compound; an optional second hydroxyl-containing compound having a single OH group, wherein; and an epoxy component. The epoxy component is present in an amount of 35% by weight or greater, based on the total weight of the polymerizable composition. The first hydroxyl-containing compound has more than one OH group and the optional second hydroxyl-containing compound is a primary alcohol or a secondary alcohol. The present disclosure also provides a two-part composition, in which the polymeric material is included in the first part and the second includes at least one amine. Further, a method of adhering two substrates is provided, including obtaining a two-part composition; combining at least a portion of the first part with at least a portion of the second part to form a mixture; disposing at least a portion of the mixture on a first substrate; and contacting a second substrate with the mixture disposed on the first substrate. The disclosure also provides a polymeric material and a method of making a two-part composition. Advantageously, two-part compositions can be used as coatings and adhesive systems with handling and performance similar to existing two-part urethane systems, but with less sensitivity to water, or with performance similar to toughened epoxy systems.
