Product samples for passivation procedures are available to industrial customers.
Traditional Passivation Line
A traditional passivation procedure production line utilizes a series of tanks that the parts are immersed in. These tanks can be of any size, made of stainless steel or plastic, heated or at ambient temperature, and can utilize ultrasonics if desired. Accelerated drying with heat is common when performing a stainless steel passivation procedure.
1. Preclean and rinse if necessary
2. CitriSurf passivation bath
3. Two or three water rinses
4. Drying
Low Volume Passivation
For low volume production with small parts, a dedicated line is not necessary. The CitriSurf bath can be a smaller, tabletop ultrasonic tank, or even a plain plastic bucket for this passivation procedure. Rinsing with flowing water in a sink is sufficient for a small number of parts, and drying in ambient air is generally fine.

Large Item and Spot Passivation
To passivate very large items, very small areas, or on-site fixtures that are not easily removable, we offer CitriSurf products in trigger sprayer and thicker gel versions so they can be sprayed or brushed onto the needed area. The gel versions are excellent for vertical surfaces and can be sprayed to cover large areas.
