PURPOSE:To provide the titled resin for the coating of exterior wall material, having specific molecular weight and glass transition point, and giving a coating film free from cracking and peeling, by copolymerizing an alkyl acrylate, fluoroalkyl acrylate and glycidyl acrylate, etc. CONSTITUTION:The objective resin having a molecular weight of 80,000-150,000 and glass transition point of 30-60 deg.C can be prepared by copolymerizing (A) 50-80mol% one or more alkyl (meth)acrylate monomer, (B) 15-30mol% one or more fluoroalkyl (meth)acrylate monomer, etc. and (C) 5-20mol% one or more monomers selected from glycidyl (meth)acrylate, tetrahydrofuryl (meth)acrylate, etc. An elastic finished structure of exterior wall can be produced by coating an external wall material with an elastic intermediate finishing material, and then with a paint composed of the above resin as the top coating layer. |
