  • Waterproofing coating compositions
    Patent number: 9663678
    Abstract: A coating composition comprises an emulsion copolymer of a monomer mixture comprising at least one vinyl ester, ethylene, and a stabilizing system. The stabilizing system comprises at least one polyvinyl alcohol. The monomer mixture comprises from 60 to 82 wt % of the at least one vinyl ester and from 18 to 40 wt % of the ethylene based on the total weight of monomers in the mixture. The stabilizing system comprises from 1 to 5 wt % of at least one medium molecular weight polyvinyl alcohol and at least one low molecular weight polyvinyl alcohol. The emulsion copolymer has a solids content from 50% to 60% and a viscosity ranges from 500 to 6,000 mPa·s. and a formaldehyde content of less than 10 ppm as determined by HPLC.
