Curable composition obtained by combining and mixing an epoxy resin composition comprising an epoxy resin, a monool and/or polyol and a compound comprising a carboxamide group, and a polyisocyanate composition comprising a polyisocyanate, a lithium halide and a urea compound, wherein the number of moles of lithium halide per isocyanate equivalent ranges of from 0.0001-0.04 and the number of urea+biuret equivalents per isocyanate equivalent of from 0.0001-0.4. The epoxy resin composition is claimed as well.

This invention relates to urethane acrylic hybrid polymer dispersion with robust dry/wet adhesion and the basecoats prepared therefrom for automotive applications. In this system, the polyurethane dispersion (PUD) prepolymer is based on a combination of polyols and aliphatic diisocyanates. The acrylic portion is based on (meth)acrylated monomers. A combination of this hybrid polymer dispersion and other resins having defined glass transition temperature (T.sub.g) values, organic and/or inorganic rheology modifiers, and different additives including pigment, dispersant, and defoamer are used to prepare waterborne basecoats having modified appearance and performance. The final coatings show excellent dry/wet adhesion to the primer for automotive applications.

Polymers suitable for forming carbon nanotube-functionalized reverse thermal gel compositions, compositions including the polymers, and methods of forming and using the polymers and compositions are disclosed. The compositions have reverse thermal gelling properties and transform from a liquid/solution to a gele.g., near or below body temperature. The polymers and compositions can be injected into or proximate an area in need of treatment.

A particulate polyurea compound a2) for reducing gloss of coatings, a resin composition and a crosslinkable composition comprising the particulate polyurea compound is provided, wherein the volume percentage of particles of the particulate polyurea compound having a diameter of smaller than 2 ?m is equal or less than 25%, and the volume percentage of particles of the particulate polyurea compound having a diameter larger than 20 ?m is equal or less than 10%.

The disclosure relates to at least one partially reacted product of an isocyanate and an amine (e.g., a reaction product comprising at least one adducted compound). The reaction product comprises polyurea oligomers. The reaction product can be combined with at least one amine in order to formulate a curing agent for epoxy resins wherein the cured epoxy resin has enhanced fracture toughness. The at least partially reacted product does not increase the viscosity of the curing agent and is at least partially soluble in the amine component of the curing agent.
