Document Type and Number:
Japanese Patent JP4821986
Kind Code:
B2
Abstract:
A method of reducing a surface glossiness of an organopolysiloxane-cured article is provided. The method comprises preparing the liquid organopolysiloxane composition for matting comprising: (A) 100 parts by weight of a thermosetting liquid organopolysiloxane composition having a specific gravity larger than the component (B), and (B) 0.1 to 100 parts by weight of a hollow filler having a melting point of at least 150° C., and a particle size of up to 200 μm, casting the liquid organopolysiloxane composition as a potting material or coating material; and curing the liquid organopolysiloxane composition at a temperature of 10 to 160 C for 30 to 180 minutes, whereby the hollow filler floats to the surface of the organopolysiloxane and forms surface irregularities on the surface of the cured article during curing to provide a surface glossiness of up to 40 in a cured article having a matted surface.
