    • The present invention relates to light fast, aqueous, strippable coating compositions containing A) 40 to 90 wt. %, based on resin solids of A) and B), of aqueous polyurethane-polyureas and B) 10 to 60 wt. %, based on resin solids of A) and B), of polymers prepared from radically polymerizable monomers,wherein the percentages of A) and B) add up to 100, based on the weight of resin solids of A) and B). The present invention relates also to substrates coated with these strippable coating compositions. In addition, the present invention relates to the use of the stripped coatings as recycled material by mechanically comminuting the stripped coatings, optionally after cleaning, and then either pressing them in heatable presses to form sheets, or extruding them in an extruder to form endless thermoplastic threads, and then processing the resulting threads by known granulating methods to form cylindrical, spherical, lenticular or rhombic granules. Finally, the present invention relates to the use of the resulting thermoplastic granules for the production of articles by known processes such as injection molding, blow molding, deep-drawing, slush molding or flat extrusion.
    • 本发明涉及一种轻质,含水,可剥离的涂料组合物,其含有A)40-90wt。 %,基于A)和B)的树脂固体,水性聚氨酯 - 聚脲和B)10至60wt。 基于A)和B)的树脂固体,由可自由基聚合的单体制备的聚合物,其中A)和B)的百分比基于A)和B)的树脂固体的重量加到100上。 本发明还涉及涂覆有这些可剥离涂料组合物的基材。 此外,本发明涉及剥离的涂层作为再循环材料的用途,通过机械粉碎剥离的涂层,任选地在清洁之后,然后在可加热的压力机中压制以形成片材,或者在挤出机中挤出以形成环形热塑性塑料 螺纹,然后通过已知的造粒方法处理所得螺纹以形成圆柱形,球形,透镜状或菱形颗粒。 最后,本发明涉及所得到的热塑性颗粒用于通过已知方法如注射成型,吹塑,深冲,搪塑或扁平挤出生产制品的用途。
