摘要： PROBLEM TO BE SOLVED: To easily repair a crack in a short time by coating the front side, the rear side and the front side of a through-wall with a reaction curing type coating material in the order and infecting a grout material into voids in a crack section. SOLUTION: A nozzle in a specified size is inserted into a crack section from the front side in the crack 3 of a wall, in which an exterior wall 2 and an interior wall 1 are laminated. A urethane foam is discharged as a coating material, and the crack section 3 on the rear side of the exterior wall is coated. Fast curing cement is used as a coating material, a pipe is inserted as the filler hole of a grout material, the exterior-wall front side is coated, and a curing acrylic resin composition is injected to the crack section 3 from the pipe and cured. Accordingly, the leakage of rainwater and the corrosion of a metal can be prevented, and the strength of a through-wall can be increased.

摘要： PURPOSE:To obtain the title composition having sufficient ability to temporarily bond various chip materials by mixing a compound containing ethylenically unsaturated bonds, a monomer containing acidic phosphate groups and unsaturated bonds, a thermal polymerization initiator, an inorganic filler, etc. CONSTITUTION:The title composition having a viscosity at 25 deg.C of 10,000 to 500,000 cP and a structural viscosity index of 3 to 6 is obtained by mixing a compound (A) having polymerizable ethylenically unsaturated bonds, a monomer (B) having at least one acidic phosphate group and at least one unsaturated group, a thermal polymerization initiator (C), an inorganic filler and/or thixotropic agent (D), and it necessary, a photopolymerization initiator (E). Because of the incorporation of component B into component A, this adhesive composition has a sufficient ability to temporarily bond a chip part even to a material to which the adherend of the chip part is hard to bond (e.g. glassy material). Therefore, it can noticeably prevent falling off of chip parts in the soldering process, which has been a problem so far.

摘要： PURPOSE:To obtain an adhesive composition curable within a short time at low temperature and excellent in adhesiveness, by mixing a compound having a polymerizable ethylenically unsaturated bond with a photopolymerization initiator, a peroxy ester and a bivalent cobalt compound. CONSTITUTION:This adhesive composition comprises a compound (A) having a polymerizable ethylenically unsaturated bond, a photopolymerization initiator (B), a peroxy ester (C) and a bivalent cobalt compound (D). It is desirable for obtaining good adhesive strength that said compound (A) contains an unsaturated polyester and/or a polyurethane poly(meth)acrylate. Because an unsaturated polyester and a polyurethane poly(meth)acrylate are usually liquid having high viscosity at room temperature and are very poor in workability as an adhesive, it is necessary to use them together with a low viscosity (meth)acrylate. In order to improve the adhesion to various materials, it is desirable to use them together with other (meth)acrylates.
