An adhesive composition comprising a core shell vinyl ester and a urethane acrylate, which is suitable to be applied to a rough or uneven surface of a substrate to render a smooth surface. The present adhesive composition is particularly suitable to coat large objects made through additive manufacturing to form molds or prototypes.

Adhesive compositions and methods for coating objects

A thermosetting composition comprising a crosslinkable component such as a vinyl ester and/or an unsaturated polyester, and an initiator component, such as cumene hydroperoxide or BPO or blends of cumene hydroperoxide and methyl ethyl ketone peroxide. The composition is suitable to be used in additive manufacturing to form objects such as molds or prototypes.

Additive manufacturing compositions and methods

Zero VOC thermosetting gel coat and laminating resin compositions, and composites and articles, are produced using a multifunctional Michael acceptor, a multifunctional Michael donor and a base catalyst. The obtained low viscosity resin is useful for producing zero VOC gel coats and laminates having excellent curability at ambient temperatures.

Acetoacetyl thermosetting resin for gel coat

A thermosetting unsaturated polyester resin (UPR) composition comprising an unsaturated polyester polymer having at least two strained cycloolefinic double bonds and optional unstrained cycloolefinic double bonds, which can be cross-linked through a ring-opening metathesis polymerization (ROMP) or combination of ROMP and cationic or free radical polymerization is provided. No styrene is used in the resin composition. The thermosetting unsaturated polyester resin composition also comprises a catalyst system for the ring-opening metathesis polymerization, and in embodiments, can further comprise one or more optional unsubstituted or substituted cycloolefin monomer containing unsaturation, an optional co-catalyst selected from a cationic initiator or free radical initiator, and optional additives. The cured resin properties can be controlled through adjusting the structure and properties of the unsaturated polyester resin.

Styrene-free unsaturated polyester

A process to disperse organic microparticles/nanoparticles into non-aqueous resin medium is provided. The process includes the steps of a) preparing a resin dispersion/emulsion in water and/or solvent where the resin contains unsaturation in the polymer chain and optionally comprises an ethylenically unsaturated monomer; b) curing the resin dispersion/emulsion by adding monomer and/or initiator; and c) adding the cured dispersion/emulsion during a synthesis step of a resin medium. The amount of organic microparticles/nanoparticles in the resin medium can be about 2 to about 30% by weight based on the total weight of the composition.

Process to disperse organic microparticles/nanoparticles into non-aqueous resin medium

The present invention related to a process to improve the adhesion between a thermosetting laminate and a thermoplastic shell in making reinforced plastic laminates for sanitary fixtures, such as shower receptors, spas, bathtubs, sinks, lavatories and the like, and composites laminates for transportation, marine, and construction applications. The adhesion improvement is through a designed post-curing process of the cured composites laminates. The thermosetting resin used in the construction of composites laminate can be unsaturated polyester resin of any kind, vinyl ester resin, or combination of both.
