20 Claims

1. A process for the application of a floor coating comprising mixing a floor coating composition with a base catalyst C and applying the obtained ready to use floor coating composition to a surface of a floor,

wherein the floor coating composition is a Real Michael Addition (RMA) crosslinkable composition comprising at least one crosslinkable component comprising reactive components A and B each comprising at least 2 reactive groups wherein the at least 2 reactive groups of reactive component A are acidic protons (C—H) in activated methylene or methine groups, and the at least 2 reactive groups of reactive component B are activated unsaturated groups (C═C) which reactive groups react to achieve crosslinking by RMA reaction between said at least one crosslinkable components in the presence of the base catalyst (C),

wherein the crosslinkable component comprising reactive component A is a polymer that is modified with fatty acids and is modified with reactive components A in the main chain, pendant, terminal or combinations thereof,

wherein the viscosity of the crosslinkable polymer comprising reactive component A as measured at 23° C. according to DIN EN ISO 3219/A.3, is from 15,000 to 200 mPa·s and

wherein the crosslinkable component comprising reactive component A has a weight average molecular weight Mw between 500 and 10000 g/mol.
