Coupon Preparation Cleaning

Q. How do I clean metal substrates in coupon preparation when testing adhesive bonds?

A. To clean metal substrates prior to use in bond testing we recommend using a warm or hot % solution of Alconox® (1.25 oz/gal or 10 g/L) followed by a thorough water rinse to clean off residues that can cause bonding problems on metal coupons.

We offer free sample here at Get Sample and also can offer detailed advice on custom applications at Ask Alconox.
