METHOD FOR IMPARTING WATER-PROOFNESS

PURPOSE:To impart excellent initial bond strength even to a wetted surface, by applying a bonding compsn. consisting of a resin emulsion and a neutral to alkaline aq. soln. of a polyvalent metal salt to a substrate. CONSTITUTION:0.2-10pts.wt. neutral to alakline aq. soln. of a polyvalent metal salt...

Zusammenfassung:	PURPOSE:To impart excellent initial bond strength even to a wetted surface, by applying a bonding compsn. consisting of a resin emulsion and a neutral to alkaline aq. soln. of a polyvalent metal salt to a substrate. CONSTITUTION:0.2-10pts.wt. neutral to alakline aq. soln. of a polyvalent metal salt such as CaCl2 is blended with 100pts.wt. (on a solid basis) resin emulsion having a solid content of 30-95wt% and contg. an emulsifier such as ammonium oleate and a polymer having a glass transition temp. of 0 deg.C or below and mainly composed of a (meth)acrylate ester of the formula (wherein R1 is H, methyl; R2 is a 1-18C alkyl, cycloalkyl) to obtain a bonding compsn. This compsn. is applied to a substrate such as polyester sheet and, if necessary, a sheet material is sticked thereon.
