摘要
介绍了一种聚酯体系的高加工性能的卷材涂料底漆,覆涂漆膜的金属卷带可冲压、折弯,且成型后性能优异。0 T折弯测试达到0级,0 T折弯后可耐70℃水煮24 h而不脱落。涂料以封端型异氰酸酯和氨基树脂为交联剂,并讨论了各种原料对漆膜性能的影响。
A polyester-based coil primer with high processability is introduced.The coil coated metal can be punched and bent,and has excellent post-forming performance.The 0T bending test reaches grade 0,and after 0T bending,it can resistent to heat water at 70℃for 24 hours and has no peeling off.The blocked isocyanate and amino resin are used as the crosslinking agent.The influence of various raw materials on the performance of the coating is discussed.
