Organoclay-Polyurea Nanocomposites with Advanced Mechanical Properties

The Innovation

Organically modified nanoclay (NC) based polyurea (PU) nanocomposites have been fabricated using commercial aliphatic or aromatic methylene diisocyanate (MDI) prepolymer resins and polyaspartate ester secondary and polyether primary amine cure agents.

Competitive Edge

Nanocomposite processing and fabrication methodology were demonstrated on dispersion and exfoliation of nanoclay in amine cure followed by degassing in vacuo at elevated temperature used in industry for PU spraying, mixing with MDI resin, casting into a mold and curing at ambient temperature.
