Patent number: 7176269Abstract: The curable composition of the present invention contains (A1) a silyl-containing ethylene/?-olefin/non-conjugated polyene random copolymer rubber which has a structural unit derived from a norbornene compound as the non-conjugated polyene with at least one specific vinyl group at the terminal and contains a specific hydrolyzable silyl group, and (B) a compound, other than the rubber (A1), having a hydroxyl group and/or a hydrolyzable group, e.g., (B1) a compound having a silanol group and/or a compound which can react with moisture to form a compound having a silanol group in the molecule. This compound improves elongation of the cured product and residual surface tackiness, and, at the same time, is high in curing speed and capable of giving the cured product of high resistance to weather. It is suitable for, e.g., adhesives, tackifiers, paints, sealants, waterproof materials, spray materials, shaping materials and casting rubber materials.Type: GrantFiled: July 24, 2001Date of Patent: February 13, 2007Assignee: Mitsui Chemicals, Inc.Inventors: Takashi Hakuta, Masaaki Kawasaki, Yoshiharu Kikuchi, Mitsunao Arino, Mitsuko Nagai, Hiroaki Sakaguchi, Masaki Sugawara, Masao Kishi, Kaoru Ueno, Takashi Abe, Michio Sekine

Patent number: 7160962Abstract: Elastomer-modified Epoxy-polysiloxane compositions of this invention are prepared by combining a silicone intermediate, with an epoxy resin, an elastomeric resinous intermediate, a polyfunctional amine, an optional organometallic catalyst, and optional fillers, pigments, and processing agents. The composition is prepared using a sufficient amount of water to promote hydrolysis of the polysiloxane and the polycondensation of the silanols produced by such hydrolysis. In its cured form, the epoxy-polysiloxane composition exists as a uniformly dispersed arrangement of linear epoxy chain fragments that are cross-linked with a continuous polysiloxane polymer chain, wherein either or both of the epoxy and/or polysiloxane polymers are elastomer modified to provide coatings and floorings having significantly improved properties of impact resistance, flexibility, crack resistance, and abrasion resistance with compared to conventional epoxy systems.Type: GrantFiled: October 27, 2003Date of Patent: January 9, 2007Assignee: Ameron International CorporationInventor: Haruji Sakugawa
