A question was posed to our Ask the Experts line wondering about the differences between plasma surface modification and corona treatment. While there are a variety of surface modification techniques to help achieve desired results, today we’ll compare some of the key advantages and considerations of plasma treatment vs. corona treatment.
Plasma treatment can readily prime any surface for adhesion, painting, coating or printing applications. Plasma is a good option for components that require a longer treatment hold before moving to the next step in manufacturing. Other key advantages of plasma treatment include:
Considerations
