摘要：: <p>The invention relates to a radiation curable binder composition for powder paint formulations. The binder composition comprises a) a polymer having a degree of unsaturation between 300 and 1800 grams per mole of unsaturated group (WPU), having a molecular weight Mn between 800 and 6800 and a viscosity between 1 dPas and 800 dPas and b) a crosslinking agent having vinyl ether, vinyl ester or (meth)acrylate functional groups. The polymer is an unsaturated polyester and/or an unsaturated polyacrylate. The binder composition can be used in the preparation of powder paint formulations which can be applied to heat-sensitive substrates such as wood and plastic and which can be cured with UV or electron beam radiation.</p>
