摘要
This resin composition for repairing sewer pipes includes: a vinyl ester resin composition (A); a urethane (meth)acrylate composition (B); an unsaturated polyester resin composition (C) having an acid value of at least 90 KOHmg/g; and a curing agent (D) including cumene hydroperoxide and t-butyl peroxybenzoate. It is preferable that 0.5-10 parts by mass of the unsaturated polyester resin composition (C) be mixed per a total of 100 parts by mass of the vinyl ester resin composition (A) and the urethane (meth)acrylate composition (B). This resin composition for repairing sewer pipes achieves both rapid curing properties, and an extension in the time period for which the composition can be stored.
