Good morning Dom, I have been hearing about DCHA being used throughout the industry. Could you tell me your opinion on the usage of DCHA? And what advantages and disadvantages do you see using this amine? <P>Thanks,<BR>Roy </P>

Dear Roy,

There is an ASTM method you should use. You will need a 6060 aluminum coupon. You place the coupon into your diluted metalworking fluid (the concentration should be the use concentration) let the sample stain over night and evaluate the coupon the next day observe the stain in the liquid phase the air phase and the liquid-air interphase. This data will help you select the best non-ferrous stain inhibitor. Also the ASTM Procedure will tell you how to prep the coupon.

Good Luck and Thanks for reading,

Dom

DCHA has both biocidal and ani corrosive properties. It also has a sharp smell and irritates some peoples eyes Bruce
