  The invention relates to a method for the production of polyisocyanate/polysilicic acid based resins with widely variable processability period and setting period by reacting one or more polyisocyanates with water glass optionally in the presence of one or more additives and/or auxiliary agents conventionally used in the production of polyisocyanate/polysilicic acid based resins. According to the invention the reaction is performed in the presence of one or more cocatalysts comprising mobile hydrogen of acidic character, wherein the cocatalyst is a compound comprising a structural unit of formula (I) a metal chelate thereof or a derivative thereof in which one of the mobile hydrogens of acidic character is replaced by a substituent X, wherein X represents halo, hydrocarbyl, hydrocarbyl-oxy, hydrocarbyl-carbonyl, hydrocarbyl-oxy-carbonyl or hydrocarbyl-carbonyl-amido group or a combined group formed from two or more of these groups, and the cocatalyst is used in an amount of at least 0.01% by weight calculated for the combined weight of polyisocyate(s) and water glass.

  The invention relates to an aqueous coating composition comprising a film-forming first polymer and a second polymer for improving the open time, the wet edge time, adhesion and/or hardness of the resulting coating. The invention further relates to said novel second polymer, its use in coating compositions for improving the open time and coalescence. The water soluble second polymer is an addition polymer comprising 25-95 wt % specific non-ionic hydrophilic monomers A and 5-75 wt % of hydrophobic monomers B which second polymer is sparingly water soluble and a solution of only said second polymer in water has a substantially Newtonian flow behaviour in a wide solid contents range.
