摘　　要：探讨了不同厂家的两种固化剂MA和MB在UP聚酯漆淋涂时引起断帘的原因。分别用黏度计(涂-4杯)和凝胶渗透色谱(GPC)研究分析了固化过程中体系黏度和相对分子质量的差异。试验结果表明:加入相同量的MA和MB后,前者随时间延长,黏度和相对分子质量增长较快,而后者变化很小。This paper discussed reasons of broken curtain in PE flow coating caused by two curing agent MA and MB from different manufacturers. Experimental results showed that when adding same amount of MA and MB, with the increasing of time, the former viscosity and molecular weight increased rapidly, while the latter changed little.

关 键 词：聚酯漆 淋涂 黏度 断帘
