LOW-TEMPERATURE-CURABLE CROSS-SECTION REPAIR MATERIAL, AND CROSS-SECTION REPAIR METHOD USING SAME

WIPO Patent Application WO/2016/133094

A1

　Provided is a low-temperature-curable cross-section repair material which can be cured in a short period of time, even in extremely low temperature environments of -25°C, and which exhibits excellent workability and strength development. Also provided is a cross-section repair method using the same. The low-temperature-curable cross-section repair material is characterized by: comprising 100 mass parts of a radically polymerizable resin composition (A), 0.1-10 mass parts of a hydroxyl group-containing aromatic tertiary amine (C-1), 0.1-10 mass parts of an organic peroxide (D), and 1.0-500 mass parts of an inorganic filler (E); and the radically polymerizable resin composition (A) comprising at least one type of radically polymerizable resin composition (A-1) selected from the group consisting of vinyl ester resins, urethane (meth)acrylate resins and polyester (meth)acrylate resins, and a radically polymerizable unsaturated monomer (A-2) having at least two (meth)acryloyl groups per molecule thereof.
