<p>Coating composition and its use in a one-pot system. The coating composition comprises: an oxidatively drying polyunsaturated condensation product, such as an alkyd, having pendant groups in an amount of more than 20 % by weight of the condensation product, the pendant groups comprising unsaturated CC bonds ; a polythiol having two or more SH-groups; a siccative. The equivalence ratio of thiol functional groups to unsaturated CC bonds being less than 0,3, preferably between 0,01 and 0,25. The coating composition comprises 1 - 30 w t- %, preferably 3 - 20 wt-%, of thiol compounds, related to the total weight o f solid resin. The coating composition further comprises a drying accelerating complexing agent, preferably 2,2'-bipyridyl or 1,10-phenantroline.</p> |
