  • Publication number: 20020127415
    Abstract: A process for modifying the functionality of organofunctional substrate surfaces by first reacting the organofunctional group of a silicon compound A with the surface of a substrate, where the silicon compound A bears at least one organofunctional group and, as other groups, bears at least one chloro, alkoxy, carboxy or hydroxyl group, then applying to the pretreated substrate an organofunctional silicon compound B, where the silicon compounds A and B are identical or different and the silicon compound B bears at least one chloro, alkoxy, carboxy or hydroxyl group. The process produces surface-modified substrates for other applications.

  • Patent number: 6444315
    Abstract: An encapsulated flame retardant is made by a process including applying an organic silicon composition to a powder flame retardant. The organic silicon composition is an organofunctional-silane or a mixture of organofunctional silanes, an oligomeric organosiloxane or a mixture of oligomeric organosiloxanes, or a solvent-containing preparation based on monomeric organosilanes and/or on oligomeric organosiloxanes, or a preparation based on water-soluble organopolysiloxanes, or mixtures of any or all of these. These surface-modified flame retardants are used in particular in polymers and polymer compounds, for rendering naturally occurring materials flame retardant, and also for the intumescent coating of combustible materials.
