[下午 03:57:39] MAR-James Lee: Hello Alina, One question came up in my mind, do u remember that when Mr. Chen of Yu Huei said they used to use the sodium chloride from Merck, but at that period, most of screws failed and got rusty after 300 - 500 hours, but after they changed to use sodium chloride from Nihon Shiyaku Industries, most of screws passed the salt spray test without rust after 1000 hours. Do u know why? Does it means the sodium chloride from Merck is more severe for testing? Could you please check with Mr. Chen for that?
[下午 04:02:03] MAR-James Lee: I know the cost of sodium chloride from Merck is much more expensive than it from Nihon Shiyaku, and the purity of sodium chloride from Nihon Shiyaku is higher than Merck's. But what I'm concerned is most of the testing Labs uses sodium chloride from Merck. Why?
