摘要： An organosilicon compound having a hydrolyzable silyl group and a catechol group in the molecule is novel. When modified by surface treatment with an adhesive composition comprising the organosilicon compound, various inorganic materials such as glass and metals become tightly adherent to epoxy and other resins.

摘要： Room temperature-vulcanizing silane-containing resin compositions are described, containing: (A) 100 parts by mass of a silane-modified polybutadiene compound represented by formula (1) (B) 0.5 to 20 parts by mass of a hydrolyzable organosilane compound having in each molecule an average of at least two silicon atom-bonded hydrolyzable groups, and/or the partial hydrolysis condensate of this hydrolyzable organosilane compound; and (C) 0.1 to 10 parts by mass of a curing catalyst. This room temperature-vulcanizing silane-containing resin composition is suitable for application as a coating agent composition and in particular as, e.g., a coating agent for electrical and electronic components and substrates therefor, and a sealant for liquid crystal display elements. The room temperature-vulcanizing silane-containing resin composition provides a gas permeation-resistant coating film (cured material) and is useful as a coating agent that exhibits a corrosion-inhibiting capability versus corrosive gases.

摘要： An epoxy resin composition comprising an epoxy resin, a curing agent, (A) a carboxyl-containing benzotriazole derivative, and (B) an alkoxysilyl-containing aminoalkylsilane derivative is suited for encapsulating semiconductor devices. The sum of (A)+(B) is 0.5-5.0 pbw per 100 pbw of the sum of the epoxy resin and the curing agent, and a molar ratio (A)/(B) is 0.5-1.5. The composition is free of sulfur and highly adhesive to metal substrates.
