Citric passivating


2002

I am wondering about how safe is it to use citric acid passivating methods? I am also wondering if there is a citric passivating method that would not allow you to use any waste disposal system that is required by EPA.

Thank you,

Dear Chris Kozka,

Citric acid passivations has shown best results in our experiments . We are concerned with surgical instruments technology. A lot of formulations are available. But we recommend Citrisurf. You may chose the grade of Citrisurf according to the alloy. It is very safe and environment friendly.
