Coating composition comprising a liquid first phase comprising one or more polymer binder components having functional groups capable of cross-linking by electron pair exchange, and a second phase which is a powder material, such as sand, comprising one or more compounds capable of activating crosslinking of the binder components in the liquid phase after the second phase is exposed to the first phase. The activating compound in the second phase may include a Lewis acid or Lewis base. Method of applying a coating composition curable by cross-linking chemistry based on electron pair exchange, wherein after application of a layer of the coating composition on a substrate, a powder material comprising one or more cross-linking activating compounds is sprinkled over the wet layer. After sprinkling the powder material over the coating layer, a second coating layer is applied.
Coating composition comprising one or more polymer binders cross-linkable by polar reaction and at least one catalyst, the cross-linkable polymer binders being comprised in a liquid phase, characterised in that a separate dry sprinkleable powder phase comprises at least a part of the catalyst and/or of a precursor of the catalyst which forms the catalyst in reaction with a co-reactive compound in the liquid phase
Method of applying a coating composition comprising in a liquid phase one or more polymer binders cross-linkable by polar reaction and in a separate dry powder phase at least one catalyst wherein after application of one or more layers of the liquid phase on a substrate, the powder phase is sprinkled over the wet liquid phase layer.
