Product performance

涂料、油墨分散剂:增加颜料在体系的分散性,最大限度的增加其着色度;增加溶解性,提高有效成分的溶解量;降低粘度来降低混合要求,提高流动性和润湿性; 1. Coating and ink dispersant: increase the dispersibility of pigment in the system and maximize its coloration; increase solubility and increase the amount of active ingredients dissolved; reduce viscosity to reduce mixing requirements, improve flowability and wettability;

涂料树脂:其大量的端基基团容易进行功能化改性,如端基含双键基团的超支化聚合物黏度低、双键官能度高、反应速度快,特别适合作为涂料树脂使用,可降低涂料体系的黏度,改善流动性,使涂料具有良好的涂装性能;同时降低溶剂用量,增加涂料固含量,减少有害气体排放;大量不饱和基团使反应活性较高,易于交联成膜,缩短干燥时间。 2. Coating resin: its large number of end groups are easy to be functionalized, such as hyperbranched polymers with double bond groups in the end groups, which have low viscosity, high double bond functionality, and fast reaction speed, and are particularly suitable as coating resins. Use, can reduce the viscosity of the coating system, improve the fluidity, so that the coating has good coating performance; at the same time reduce the amount of solvent, increase the solid content of the coating, reduce harmful gas emissions; a large number of unsaturated groups make the reaction higher, easy to cross Co-film formation, shortening drying time. There is a wide space for applications in the coating industry, such as UV curing coatings, powder coatings, water-based coatings, etc., especially as UV curing coatings;

工程树脂:在热塑性树脂中引入超支化聚合物能较大地改善树脂的加工性能和力学性能 , 而在热固性树脂如 EP 中引入超支化聚合物 , 也可能会带来一些前所未有的性能改进等; 3. Engineering resins: The introduction of hyperbranched polymers in thermoplastic resins can greatly improve the processing properties and mechanical properties of resins , while the introduction of hyperbranched polymers in thermosetting resins such as EP may also bring some unprecedented performance improvements, etc. ;

塑料加工助剂:在显著改善流动性的同时,提高拉伸等机械性能;大幅度降低加工电流和熔体压力4. Plastic processing aids: while significantly improving fluidity, improving mechanical properties such as stretching; greatly reducing processing current and melt pressure .
