Title:
PRIMER COMPOSITION, WATERPROOF FLOOR SLAB STRUCTURE USING SAME, AND METHOD FOR WATERPROOFING FLOOR SLAB
Document Type and Number:
WIPO Patent Application WO/2011/040384
Kind Code:
A1
Abstract:
Provided is a primer composition which is useful in applying a radical-curable resin based waterproofing material to concrete floor slabs of existing or newly-established highway bridges or the like. The primer composition is suitable for use in applying a radical-curable resin based waterproofing material for floor slabs, said radical-curable resin based waterproofing material overcoming the problems of troublesome application including use of a large-sized machine. The primer composition is a resin composition which comprises (A) a urethane (meth)acrylate resin, (B) a polymerizable unsaturated monomer that comprises (B-1) a hydroxyalkyl (meth)acrylate and (B-2) other polymerizable unsaturated monomer, (C) a cure accelerator, (D) a paraffin wax, and (E) a drying assistant and which is characterized in that the above components satisfy a specific molar ratio and specific mass ratios. The primer composition exhibits excellent crack-load following properties, blistering resistance, adhesion, and bending resistance. Also provided are both a waterproof floor slab structure using the primer composition and a method for waterproofing a floor slab.
