Utilización de una composición estabilizadora para aumentar el Tiempo Abierto de una composición de revestimiento acuosa, donde la composición estabilizadora comprende un polímero tipo AB, donde B comprende cualquier tipo de oligómero o polímero soluble en agua/dispersable en agua seleccionado del grupo consistente en polietilenglicol, poliacetalpoliéter (PAPE), acrilato, acrilamida y óxido de polietileno; y donde A, unido de forma covalente a B, comprende una estructura que tiene la siguiente fórmula: **Fórmula** donde R comprende un hidrocarburo C1 a C30, lineal o ramificado, alifático o aromático, o combinaciones de los mismos; R1 comprende H, CH3 ó C2H5; R2 comprende CH2O, CO2, CONH ó CH2 y pudiendo ser R2 igual o diferente; R3 comprende H u OH; n es un entero de 1 a 100; y m es 0 ó 1. A stabilizer composition comprising an AB type polymer for use in increasing Open Time of aqueous coating compositions is disclosed. The stabilizers compositions are of utility in many aqueous compositions including paints, stains, varnishes, adhesives and inks. Of particular interest is the use of the stabilizer compositions for in increasing the Open Time of latex paints as well as alkyd emulsion paints.
