In my August 2011 column, I responded to a question regarding the benefits of Chemetall’s Oxsilan pretreatment process versus more conventional iron and zinc phosphate pretreatments. There were some potential benefits that I had outlined, although I was contacted by Chemetall product manager Gary Nelson who provided further information beyond what I described to the reader. I want to thank Gary for reading and especially providing the additional detail on Chemetall’s process.
Below are some specific updates from Gary regarding the Oxsilan paint pretreatment technology that was not covered in that previous column:
Hopefully this will add some additional information for those considering this chemistry in their pretreatment line.
