Abstract: A powder coating composition blend comprising a crosslinkable composition and a catalyst system, wherein the crosslinkable composition is formed by a crosslinkable donor component A and a crosslinkable acceptor component B that are crosslinkable by a Real Michael Addition (RMA) reaction via the catalyst system, wherein the catalyst system is a separated catalyst system that comprises a catalyst precursor composition (P) and a catalyst activator composition (C) that are macrophysically separated; or wherein the crosslinkable donor component A and the crosslinkable acceptor component B are macrophysically separated.
