The present invention relates to a resin composition that comprises an acetoacetate ester compound with at least two acetoacetate ester functional groups, an acrylate compound with at least two acrylate functional groups, and a tertiary amine curing catalyst. This resin composition acts as an isocyanate-free binder that is less toxic to the environment. The invention further discloses a method for preparation fiber reinforced parts comprising fibers and said resin composition as well as a method for the preparation of foundry molds for the casting industry, which is based on said binder.

Using SWNT-CA as scaffolds to fabricate stiff, highly conductive polymer (PDMS) composites. The SWNT-CA is immersing in a polymer resin to produce a SWNT-CA infiltrated with a polymer resin. The SWNT-CA infiltrated with a polymer resin is cured to produce the stiff and electrically conductive composite of carbon nanotube aerogel and polymer.

A sealing body for dynamic applications has a Shore A hardness of between 60-100, comprising an elastomer material and carbon nanotubes distributed in the elastomer material in an amount of between 0.1-20 phr, with respect to the total amount of elastomer material.

An article with an erosion protection layer. The erosion protection layer may include metal, intermetallic compound, ceramic or glass nanocellular foam particles or monolithic sheets. The particles are dispersed in a polymeric matrix and the monolithic sheets are infiltrated with polymeric material. The nanocellular foam ligaments have submicron cross-sectional diameters.

Discrete, individualized carbon nanotubes having targeted, or selective, oxidation levels and/or content on the interior and exterior of the tube walls are claimed. Such carbon nanotubes can have little to no inner tube surface oxidation, or differing amounts and/or types of oxidation between the tubes' inner and outer surfaces. These new discrete carbon nanotubes are useful in plasticizers, which can then be used as an additive in compounding and formulation of elastomeric, thermoplastic and thermoset composite for improvement of mechanical, electrical and thermal properties.

An intumescent polymer is provided for molding fire-retardant structures. Expandable graphite is mixed in a polymer matrix to form the intumescent polymer. The expandable graphite is treated with silane to improve the strength of the polymer. Other ingredients may also be included within the polymer, including an acid source, blowing agent, char forming agent, an inorganic filler and a cross-linking agent.
