Composition of Phosphating Chemical


Dear sir,

We are using phosphating chemical for our rubber adhesion property, I want to know the composition of Phoscoat.

Hello, D. This is covered in the Metal Finishing Guidebook, Vol. 2, "Organic finishing". But I don't know if you should be using iron phosphate or zinc phosphate.

We can't tell from your posting whether you are inquiring about the chemical composition of the phosphating bath or of the coating which is imparted onto the work.

Experience seems to demonstrate that our readers will not provide data in response to abstract questions. Please try to make your problem concrete with some details about what it is that you are building, how you are doing it, and why. Thanks, and good luck.
