| 摘要 |
The invention relates to a radiation-curable powder paint binder composition comprising a resin and optionally a crosslinker in which more than 0,5 mol % of the total amount of polymerizable unsaturation of the binder composition results from itaconic acid ester units. The polymer can be a polyester, a polyacrylate, a polyolefin or an addition product of epoxy resins and itaconic acid. The binder composition can result in matte powder coatings. |
