  • Publication number: 20150126677
    Abstract: Provided is a inorganic fine particle dispersant comprising, as an essential component, a compound resin (A) in which a polysiloxane segment (a1) having a structural unit represented by general formula (1) and/or general formula (2) and a silanol group and/or a hydrolyzable silyl group is bonded to a vinyl-based polymer segment (a2) through a bond represented by general formula (3). An inorganic fine particle dispersion liquid that contains the inorganic fine particle dispersant and inorganic fine particles, an inorganic fine particle dispersion containing the inorganic fine particle dispersion liquid, a paint, and a cured product are also provided.

  • Publication number: 20130146138
    Abstract: Provided is a shaped article having surface irregularities, including a fine structure including projections and a recess formed between the projections, the fine structure formed by curing a curable resin composition, wherein the curable resin composition contains a composite resin (A) in which a polysiloxane segment (a1) having a structural unit represented by a general formula (1) and/or a general formula (2) and a silanol group and/or a hydrolyzable silyl group is bonded to a vinyl-based polymer segment (a2) having an alcoholic hydroxy group through a bond represented by a general formula (3), and polyisocyanate (B); a content of the polysiloxane segment (a1) with respect to total solids weight of the curable resin composition is 10% to 60% by weight; and a content of the polyisocyanate (B) with respect to total solids weight of the curable resin composition is 5% to 50% by weight.

  • Publication number: 20130068304
    Abstract: There is provided a sealing material including a composite resin (A) including a polysiloxane segment (a1) having a structural unit represented by general formula (1) and/or general formula (2) and a silanol group and/or a hydrolyzable silyl group and a vinyl-based polymer segment (a2) having an alcoholic hydroxyl group, the vinyl-based polymer segment (a2) being bonded to the polysiloxane segment (a1) through a bond represented by general formula (3), and a polyisocyanate (B), wherein the content of the polysiloxane segment (a1) is 10% to 50% by weight relative to the total solid content of a curable resin composition, and the content of the polyisocyanate (B) is 5% to 50% by weight relative to the total solid content of the curable resin composition. There are also provided a solar cell module and a light-emitting diode that each use the sealing material.
