CURABLE COMPOSITIONS, SEALING MATERIAL, AND ADHESIVE

摘要

Curable compositions capable of giving a cured article excellent in weatherability and flame retardancy. 1 One of the curable compositions comprises an organic polymer having at least one crosslinkable hydrolyzable silyl group and a phyllosilicate. It has enhanced weatherability due to incorporation of the phyllosilicate, and has further enhanced weatherability because the bleeding of an ultraviolet absorber and a light stabilizer is inhibited. 2 The other composition comprises 100 parts by weight of a urethane resin, epoxy resin, and/or modified polysulfide resin and 0.1 to 100 parts by weight of a phyllosilicate. It has enhanced weatherability due to incorporation of the phyllosilicate, and has further enhanced weatherability because the bleeding of an ultraviolet absorber and a light stabilizer is inhibited.
