Abstract:
1. A stabilizer composition for use in increasing Open Time of an aqueous coating composition comprising an AB type polymer, wherein B comprises a water-soluble/water dispersible oligomer or polymer and wherein A, covalently connected to B, comprises a structure that has the following formula: wherein R comprises a C R R R n is an integer from 2 to 100; and m is either 0 or 1; wherein “A” is made from a monomer selected from the group consisting of polyphenoxy glycidyl ether, methylphenyl glycidyl ether, ethylhexylglycidyl ether, phenyl glycidyl ether, and alkali glycidyl ether, and wherein “B” comprises polyacetalpolyether (PAPE); and wherein the addition of at least 0.5 wt % of the AB type polymer to an aqueous coating composition increases the Open Time of the aqueous coating composition by at least 10% Open Time, as measured by at least one of Open Time X-test A&D and Open Time X-test RC.
