  • Publication number: 20210130659
    Abstract: 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/mm2 or 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.

  • Patent number: 9695346
    Abstract: The present invention provides an adhesive for floor structure that can provide a floor structure inhibiting floor squeaks or joint gaps from occurring and that enables a floor finishing material to be peeled easily from a sub-floor material when repairing the floor finishing material. The adhesive for floor structure of the present invention contains a hydrolyzable silyl group-containing polyoxypropylene-based polymer (I), calcium carbonate, and a hollow filler. The adhesive for floor structure of the present invention can be used for adhesively integrating a floor finishing material 20 with a sub-floor material 30 laid on a floor base 1.

  • Patent number: 7135518
    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.
