  • Patent number: 6660374
    Abstract: A radiation-curable composition in a liquid or solid form comprises at least one solid, non-crystalline radiation-transmissible material, dispersed in at least one cationic-curable or free-radical curable composition or mixture thereof. The solid, non-crystalline radiation-transmissible materials comprise glasses and other suitable materials that transmit (i.e., are transparent to) at least about 40% of radiation having a wavelength from about 180 to about 600 nanometers. The cationic-curable compositions comprise at least one cycloaliphatic epoxide, at least one polyol, and at least one cation-generating photoinitiator. The free-radical curable compositions comprise at least one ethylenically unsaturated compound and at least one free-radical-generating photoinitiator unless electron beam curing is used, in which case the amount of photoinitiator can be reduced or even eliminated.

  • Patent number: 6350792
    Abstract: A radiation-curable composition in a liquid or solid form comprises at least one solid, non-crystalline radiation-transmissible material, dispersed in at least one cationic-curable or free-radical curable composition or mixture thereof. The solid, non-crystalline radiation-transmissible materials comprise glasses and other suitable materials that transmit (i.e., are transparent to) at least about 40% of radiation having a wavelength from about 180 to about 600 nanometers. The solid forms of the radiation-curable compositions of the invention are useful as powder coatings for coating decorative and functional objects and that would be cured by a thermal heating flow process followed by radiation exposure. The cured compositions of the invention are useful as coatings and inks for metal, paper, plastics, glass, ceramics, and wood, as adhesives, as sealants, and as composite materials and other articles and in biomedical and dental applications.

  • Patent number: 5356446
    Abstract: The present invention relates to a method of providing thermal insulation and fire-resistance to buildings, by filling voids or spaces in and around structural members with a low density thermally insulating and fire-resistant cementitious composition containing a high proportion of a relatively smooth-surfaced, vesicular, expanded perlite. The method includes placing a flexible, woven, fire-resistant bag in the space to be filled, so as to act as a containment vessel, pumping a cementitious composition into the bag to fill a space by conforming to the shape of the space, while the bag simultaneously contains the cementitious composition in the desired position, and allowing the composition to cure into a lightweight, fire-resistant, and thermally insulating concrete. The method is particularly useful in and directed to remedial, post-construction applications in occupied buildings.
