Autophoretic for parts with Residual Stresses
2006
We are looking forward to install AUTOPHORETIC line shortly. I have few queries:
What is the Salt Spray life of the components if residual stresses are present in the component? Will the life reduce and by how much
%?
What are the Non-Chloride type of paints? I have information that ACC
800 series has PVDC. Can we have Polyvinyledene Fluoride?
ACC 800 series is denoted by 866. What does this number designate? What is the meaning of 8, 6, 6? Similarly what is RR2150?
What is the possibility of deposition of this paint on hard chrome plated surface?
As we don't have information on the chemicals used in the process, I want to ask if there are any Hazardous chemicals used?
Please, guide me as early as possible.

These questions should be asked of your painting suppliers.
Residual stress can cause warping during baking. Tell your steel supplier the amount of residual stress from your forming operations, plus the baking temperature, to learn whether this will may a problem for your particular alloy.
Residual stress reduces corrosion resistance, but salt spray results depend mostly upon the coating quality.
"As we don't have information on the chemicals used in the process"?
-- One should have such information prior to making business decisions.
