Does Corona treatment make PP adhere better with Acrylic glue?
I am just learning about Corona treatment. My problem is to make PP or PE (or a PP CoPolymer) able to be glued with a 2-part acrylic glue. Will Corona treatment make these materials more glue-able? Someone mentioned a UV treatment instead of Corona -- does that work?

John, treating parts with a corona is used as a means to improve the paint adhesion on PP and PP copolymer materials. The best way to find out if it will work with your adhesive would be to actually test some parts. I have been told the adhesion improvement with corona treatment is short lived, that is the parts should be painted or glued as soon as possible after the treatment to get the maximum effect. This may not have answered your question, but the testing will.Roy Nuss
