Guidelines:指南
Should be checked that the sum of epoxy equivalents + OH equivalents in Megamid XL must be equal or higher than 95% of acid equivalents in the employed polyester (example 1: acid equiv= 0.315, Epoxy equiv =0.21, OH equiv = 0.096, Example 2 acid equiv = 0.366, Epoxy equiv =0.209, OH equiv = 0.139)
应检查在Megamid XL中环氧当量+ OH当量的总和必须等于或高于所用聚酯中酸当量的95%
(例1:酸当量= 0.315,环氧当量= 0.21,OH当量= 0.096 。
例2酸当量= 0.366,环氧当量= 0.209,OH当量= 0.139)

The application conditions can affect the gloss, adhesion, chemical resistance and impact resistance. Reduced time or temperature in the curing process may result in decreased the properties of final coating. Take pout this phrase
Since powder coatings are many sensitive to the change of variables and in spite that the quality of THYOSIL Q6045 it is very steady, it is highly recommended to test carefully the other components and the kind of composition, equipment, processing and application conditions to make necessary adjustments to assure correct properties batch to batch.
应用条件会影响光泽,附着力,耐化学性和抗冲击性。 固化过程中减少的时间或温度可能导致最终涂层的性能降低。 要剔除这些缺陷, 由于粉末涂料对变量的变化很敏感,尽管THYOSIL Q6045的质量非常稳定,但强烈建议仔细测试其他成分以及必要的成分,设备,加工和应用条件。 调整以确保批次到批次的正确属性。
