  • Patent number: 7886499
    Abstract: An emulsion composition for building exterior walls is provided comprising in admixture, [A] a graft copolymerized emulsion obtained by adding to (1) an oil-in-water type emulsion containing at least one organopolysiloxane having an organic group containing a radical reactive group or SH group, (2) a monomer or monomeric mixture containing at least 70 wt % of at least one monomer selected from acrylic and methacrylic monomers and effecting emulsion graft polymerization of component (2) to the organopolysiloxane, and [B] a silicone resin-containing emulsion. The emulsion composition is capable of forming an elastic, flexible coating which is endowed with water resistance, weather resistance, water repellency, adhesion and heat resistance and maintains these properties over a long period of time. It can thus be used as a base in a variety of paints and coating agents.

  • Patent number: 7659044
    Abstract: A photoconductor comprising a photosensitive layer disposed on a support, wherein the photosensitive layer has a crosslinked layer and the crosslinked layer is produced by curing a dispersion in which at least one of an acryl-modified polyoraganosiloxane having a radical reactivity and an acryl-modified polyoraganosiloxane having an amine structure is dispersed in a radical polymerizable monomer.

  • Publication number: 20040266935
    Abstract: An emulsion composition comprises a graft copolymerized emulsion obtained by adding a monomer or monomeric mixture containing at least 70% by weight of a (meth)acrylic monomer to an oil-in-water type emulsion containing an organopolysiloxane having an organic group containing a radical reactive group or SH group, and effecting emulsion graft polymerization of monomer to organopolysiloxane. The emulsion composition is capable of forming an elastic, flexible coating having weather resistance, water resistance, water repellency, adhesion and heat resistance and maintaining these properties over a long period of time, and thus suited for building materials.
