How to remove PVD from Plastic?
Q. How do you remove PVD from plastic? I have an application that requires coating of a part that has both SUS & Plastic. The part geometry is complex (difficult to mask the Plastic) so I decided to coat the full part as is. Now the challenge is getting rid of PVD from the plastic portion. Any advise on how to remove PVD?

A. Hi Brian. PVD means Physical Vapor Deposition, but it doesn't tell us what material you have deposited onto the plastic. And some plastics like Teflon are resistant to almost everything, while others like nylon and styrofoam are not. I assume SUS means stainless steel. Can you give details of exactly what you'd like to strip from what? Thanks.

A. Dear Brian,
You say it's difficult to mask. However, that would be the best way to go. It would initially cost you a bit, but it would be worth the cost and hassle especially if you are needing large scale quantities of the coated component.
It would be next to impossible, to strip PVD coating off the plastic without damaging the plastic, especially if you have used organic base coats in the process.
Good luck!
