Abstract
Curable compositions capable of giving a cured article excellent in weatherability and flam retardancy. (1) One of the curable compositions comprises an organic polymer having at least one crosslinkable hydrolysable silyl group and phyllosilicate. It has enhanced weatherability due to incorporation of the phyllosilicate, and has further enhanced weatherability because the bleeding of an ultraviolet absober 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 of weight of a phyllosilicate. It has enhanced weatherability due to incorporation of phyllosilicate, and has further enhanced weatherability because the bleeding of an ultraviolet absorber and a light stabilizer is inhibited.
