The present invention provides a synthetic resin composition from which a combustion residue produced by combustion is rigid. The synthetic resin composition of the present invention is configured such that the strength of the combustion residue of the composition after combustion in an atmosphere of 800° C. for 20 minutes is 0.5 N/mmor more. Thus, the combustion residue produced by combustion is very rigid. The combustion residue is capable of reliably holding a state where a joint part is filled therewith and clogged even during a fire, preventing flames from passing through a sealing part such as the joint part, and imparting excellent fire-proof performance to a wall part of a building construction.

Synthetic resin composition, fire-proof material, sealing material, adhesive, and joint structure

The present invention provides a curable composition excellent in rubber elasticity, coating film strength, coatability, and adhesion to a waterproof base and the like. The curable composition of the present invention contains a polyalkylene oxide having a hydrolyzable silyl group, and feldspars having an average particle diameter of 0.01 to 100 μm, and preferably further contains calcium carbonate. The feldspars may preferably contain nepheline syenite. The curable composition can form a cured product having excellent rubber elasticity and coating film strength, and excellent adhesion, while being low in viscosity and excellent in coatability.

Curable composition and coating film waterproofing agent

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.
