Abstract
The invention is directed to a crosslinkable flame-retardant coating composition comprising the following components: a) a dendritic polymer having hydroxyl groups, wherein the dendritic polymer has a hydroxyl number in the range of 80 to 800, b) a polyol having at least 3 hydroxyl groups, c) an ammonium polyphosphate compound, d) a base coat polymer selected from a polycarbamate resin or a polymer bearing carboxyl groups, and e) a crosslinker for crosslinking the base coat polymer selected from a compound having two or more aldehyde groups, acetals or hemiacetals of the aldehydes, or a polycarbodiimide. Such a cross-linkable flame-retardant coating composition improves the overall appearance of the cross-linked base coating on a substrate and also imparts improved flame-retardancy.
