Abstract: Provided is a curable composition which forms a cured product that has excellent fireproof performance, while having excellent shape retainability even in cases where the expansion ratio of the cured product after firing is set to a high value. This curable composition includes a shape retention agent, while having fluidity when applied; and if a cured product that is obtained by curing this curable composition is fired in 600° C. air atmosphere for 30 minutes, the cured product after firing has shape retainability.

Abstract: A two-component adhesive includes agent A containing an epoxy resin and agent B containing a polymer having a crosslinkable silicon group and an epoxy resin curing agent, wherein agent A and/or agent B contain(s) a core-shell rubber particle, and a condensation catalyst for the crosslinkable silicon group. Another adhesive contains an epoxy resin, a core-shell rubber particle, a polymer having a crosslinkable silicon group, an epoxy resin curing agent, and a condensation catalyst for the crosslinkable silicon group, wherein a cured product of the adhesive has a breaking strength (tensile strength at rupture) of 5 MPa or more and an elongation at break (elongation at rupture) of 30% or more, and has storage elastic moduli at 1 Hz in tensile mode of 100 to 1000 MPa at 20° C. and 50 to 1000 MPa at 80° C.

Abstract: A moisture curable composition excellent in transparency, operating efficiency and storage stability, and is suitable for use as an adhesive and a sealing material is provided. The moisture curable composition produced by blending 100 parts by weight of a mixture (A) and 2 parts by weight to 300 parts by weight of amorphous powder (B). The mixture (A) comprises (1) a copolymer having reactive silicon groups which can be cross-linked by hydrolysis, whose molecular chain substantially consists of (i) alkylacrylate and/or alkylmethacrylate monomeric units having an alkyl group with 1 to 8 carbon atoms, and (ii) alkylacrylate and/or alkylmethacrylate monomeric units having an alkyl group with 10 or more carbon atoms, and (2) a polymer substantially consisting of oxyalkylene including reactive silicon groups which can be cross-linked by hydrolysis. The amorphous powder (B) has a grain diameter ranging from 0.01 &mgr;m to 300 &mgr;m.
