LDC IS PLEASED TO ANNOUNCE APPROVAL BY P&W OF ITS SULFAMATE NICKEL

The approval of the LDC sulfamate nickel is the culmination of 2 1/2 years of evaluation.

The LDC solutions provide not only a second source, but a solution that is significantly more operator friendly. Key points are:

• a constant amp hour factor over the life of the solution;
• more useable amp hours per gallon.

Try it, you'll like it !!

With the attaining of the P&W approval we thought it might be good to list the approvals that LDC has for you.

It also might give you a broader view of the scope of your brush plating capabilities.
