<p>PURPOSE:To attain high strength close to that of welding by injecting corner connecting resin comprising a two-liquid mixing and hardening type solventless urethane resin having a specified tensile elastic modulus in a corner portion of a bay window sash or the like. CONSTITUTION:A corner connecting resin 3 is manufactured from a two-liquid mixing and hardening type solventless urethane resin having a tensile elastic modulus of 2X10<-3>kg/cm<2>-2kg/cm<2>. The corner connecting resin 3 is injected in a corner portion 1 of a bay window sash, a coping, a guard rail or the like and hardened. Thus, high strength close to that of welding can be attained at a cost lower than that of welding without any skilled work.</p> |
