Patent number: 12281240Abstract: 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.Type: GrantFiled: May 8, 2019Date of Patent: April 22, 2025Assignee: SEKISUI FULLER COMPANY, LTD.Inventors: Takuto Ikeuchi, Yukihiko Murayama

Patent number: 11981792Abstract: 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 ?m, 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.Type: GrantFiled: January 11, 2019Date of Patent: May 14, 2024Assignee: SEKISUI FULLER COMPANY, LTD.Inventor: Takuto Ikeuchi
