A tin (II) salt of an organic acid with no more than ten carbon atoms is then emulsified in water with a surfactant, and added as the component (C) to the emulsion of condensation crosslinkable silicone composition. This crosslinks the emulsion of condensation crosslinkable silicone composition.

  • Patent number: 6433041
    Abstract: An efficient method is provided for producing water based coating compositions that are capable of forming highly scratch and abrasion resistant matte coatings in which crosslinked silicone particles are well dispersed. The method involves addition to a water based coating composition of a waterborne suspension of crosslinked silicone particles having an average diameter of 0.1-200 &mgr;m. The method is characterized in that the suspension is a waterborne crosslinked silicone particle suspension provided by effecting crosslinking of a condensation reaction crosslinkable silicone composition comprising (A) an organopolysiloxane containing at least two silanol groups in each molecule, (B) a crosslinker, and (C) a condensation reaction catalyst. The crosslinking is effected in the emulsified composition in an aqueous solution of an anionic surfactant.

  • Patent number: 6383659
    Abstract: An epoxy resin composition comprising an epoxy resin containing 0-10% by weight of a 2-nucleus compound and 50-100% by weight of 3 to 5-nucleus compounds combined and having a dispersity (Mw/Mn) of up to 1.7, an inorganic filler, a curing catalyst, a thermoplastic resin, and an optional phenolic resin and having a Tg of lower than 15° C. in an uncured state is effective in forming a flexible film which is easy to work at room temperature. Owing to the thermoplastic resin added, the composition avoids the problem that when a semiconductor chip is sealed with an uncured film of the composition, the film will lose its original shape or entrapped voids will be formed near the chip.
