  • Patent number: 8173724
    Abstract: The invention provides a fire resistant material and a formulation thereof. The formulation comprises a liquid suspension of a modified inorganic particle and an organic component. The modified inorganic particle comprises an inorganic particle with hydroxyl groups and a surface modifier coupled to the inorganic particle via a urethane linkage, wherein the surface modifier has an ethylenically unsaturated end group. The organic component comprises a monomer, oligomer, prepolymer, polymer, or combinations thereof, capable of reacting with the ethylenically unsaturated end group.

  • Publication number: 20110082226
    Abstract: Disclosed is a multi-isocyanate prepolymer formed by reacting diisocyanate and/or diisocyanate trimer with diol and/or triol. Because the prepolymer and the diol/triol have similar molecular weights, additional crosslink agents such as diamine, multi-amine, or combinations thereof are not necessary. Furthermore, the prepolymer can be blown to form foam, or directly gelled to form an unbubbled product such as film.

  • Patent number: 7662983
    Abstract: Disclosed are modified inorganic particles and methods of preparing the same. The modified inorganic particle comprises an inorganic particle with hydroxyl groups, and a surface modifier coupled to the inorganic particle via a urethane linkage, wherein the surface modifier has an ethylenically unsaturated end group. The method comprises providing an inorganic particle with hydroxyl groups; providing a surface modifier with an isocyanate group at one end and an ethylenically unsaturated group at the other end; and mixing the inorganic particle with the surface modifier for reaction such that the surface modifier is coupled to the inorganic particle.
