  • Rubber-modified epoxy resin composition
    Patent number: 6624260
    Abstract: By using a curable composition comprising, (A) per 100 parts by weight of an epoxy resin, (B) from 1 to 50 parts by weight of a reactive silicon group-containing polyoxyalkylene polymer, and (C) from 1 to 90 parts by weight of a curing agent for epoxy resins, the working properties of an existing rubber-modified epoxy resin are improved to thereby give stable adhesion properties (for example, improved peel strength) without worsening the shear strength.
    Type: Grant
    Filed: April 13, 2001
    Date of Patent: September 23, 2003
    Assignee: Kaneka Corporation
    Inventors: Katsuhiro Ando, Junji Takase, Fumio Kawakubo

  • Process for fitting glass members onto vehicles
    Patent number: 5952052
    Abstract: The present invention has its object to a method for glazing a motor vehicle by direct glazing using a novel curable resin composition. A method for glazing a motor vehicle by direct glazing, which comprises using, as a sealant, a curable resin composition comprising (A) an oxyalkylene polymer having at least one silicon group containing a hydroxyl or hydrolyzable group bound to a silicon atom and capable of crosslinking by silanol condensation reaction, (B) carbon black, and (C) an oxyalkylene polymer not containing a crosslinking group is provided.

  • Curable resin composition
    Patent number: 5889124
    Abstract: A curable resin composition containing (a) an oxyalkylene polymer which comprises at least one silicon-containing group having at least one hydroxyl or hydrolyzable group bonded to a silicon atom, (b) an epoxy resin, (c) a ketimine compound and (d) a carbonyl compound, which has improved storage stability.
