Plasma or corona treatment of plastics before metallizing

1998

I am trying to plate nylon and spandex fabrics with metals and am looking for information about the effectiveness of plasma or corona applications to prepare the surface of the polymer. Also looking for how-to advice

thanks much.

Russ,

You might look at the Proceedings of the Annual Technical Conference of the Society of Vacuum Coaters. Every year they have a number of papers on plasma treatment of polymer surfaces for enhanced adhesion of films deposited by vacuum deposition.

I am researching surface treatments for polymers (polyurethanes, Teflon, etc.) which will improve the adhesion of printing inks. Currently use a batch plasma treatment prior to printing with adequate results. However, I would like to explore other processes and technologies (corona?). Seeking knowledge.

Thanks.

Scott,

Both corona and flame treatments are used to activate surfaces in air for printing.

The company I work for puts down metal films on plastic using plasma based methods. First they are cleaned with an Argon glow discharge (corona). This removes oxide build up (which is typically bad for adhesion) and breaks some of the polymer bonds leaving free radicals which are ready for bonding to the deposited metal(s).

We are trying to find a better way to screen print Polyethylene and Polypropylene lids for plastic boxes. Currently we flame threat them, but have difficulty stopping warping of the lids and distortion. Have heard of a Corona Discharge process being used to treat the lid before printing.

Please can you direct me.

Many Thanks

I am trying to reduce the adhesion of rubber parts. I am looking for information about surfaces treatments (plasma, corona discharge).

thanks.

I found a treatment that works on atmospheric conditions and potential free (no corona!). It has an excellent effect on TPE (Santoprene), PP, PE etc. and metals in one procedure.

Welcome to finishing.com, folks! This forum is for camaraderie and public sharing of technical information. If you've found such a treatment, please tell us what it is, don't just tell us you found it :-) (If you are making a commercial offering, you are invited to advertise on this site; but we can't ask our supporting advertisers, who generously make this forum possible, to pay for commercial postings by their competitors).

I am looking for a treatment that could be applied to the surface of silicone rubber to allow screen printing to be done. Would corona or plasma treatment be the answer as silicone rubber is well known for its release property? Thanks.

I am researching surface treatments (especially corona!) for PE film, Rubber, EVA. So I need information about corona treatment, equipments,

Please give me response...

We are a converter company based in Turkey, covering various films such as PE,OPP;PET,PVC,etc that handles over 15.000 tons of film per annum and uses corona treatment in our plant currently.

Plasma treatment is considered as one of the newest techniques which enables the enhancement of the metal adhesion on the film surface better than the regular metallization application.

I would be very pleased to get a detailed information.

Best regards,

Plasma surface treatment is widely used to improve adhesion to most polymeric materials. The technology is most widespread in the Medical device industry and has been around for a very long time.

Looking for literature and/or technical papers on Corona and Flame Plasma treatments. Haven't been successful finding any on the net. If anyone has any idea where such papers are located (other than my local library), please post it here. Thanks

I want to metallize a plastic surface, at the moment I am finding it hard to get Chromium and Titanium to stick to it. Are there any useful methods that I could use to treat the surface (this plasma method looks promising) and any methods for applying metal to the surface. Don't hesitate to respond. I am a research student.

If electrochemical methods fail, try plasma clean and vacuum sputtering. It may be available at your university.

I need to know the best way to prepare fiberglass surfaces (Polyester resin) for adhesion. I am familiar with Corona discharge treatment, but I want to know will UV treatment work as well?

Dear Sirs,

I have a product where I am screening a plastisol onto a polyester twill fabric. The plastisol ink does not adhere strongly to the polyester fabric, would corona treating the polyester fabric before the ink applied increase the adhesion enough so that the plastisol ink will go through a home laundry?

We have experience working with various technologies including Flame Treatment, Corona Treatment, and Modified atmosphere Treatment. Each has their place you will need to work with a supplier of such equipment to determine which technology is best for you. Most companies have access to these technologies and will work with you at no charge to determine what works best for you.

Corona treatments are short lived processes for plastics and usually require an in line process such as treating films for metallizing or application of pressure sensitive treatments. In vacuum plasma is a lifetime treatment of plastic materials as well as elastomers. Storage of treated materials is not limited by time. Various chemistries of gas, RF energy and vacuum are used to produce dramatically improved adhesion for inks, adhesives, paints, etc.
