Features of different modifi cation methods for the powder coating ssystem including mixing silicone additive or resin with general organic resin , using sili cone containing resin or using silicone resin j ust as a curing agent are described. The introduction of silicone composition to the powder coatings improves some properties and performance of the cured film especially in the thermal stability and weather resis tance . The future development tendency and application of silicone modified powder coatings are previewed. Key words : silicone resin ; powder coatings ; modification 　　粉末涂料作为一类绿色环保型涂料近年来在众 效途径 。 多领域特别是金属涂装
