Plasma processes: clening, activation, coating, priming

Plasma-cleaning

Surface cleaning is a very important application for Plasma surface technology.
During this process dirt particles are removed by chemical reactions with the ionized gases.
The unwanted contamination on the surface of the product is solved into the gas phase and removed by the pumping system.

A continues gas flow transports the contamination away from the product.
Other dirt or contamination particles are removed by ion bombardment and are carried away by the gas flow.
The surface is cleaned residue-free by the plasma.

Plasma-activation

During plasma-activation free radicals are formed on the plastics surface by the reactive spiecies of the plasma and functional groups are attached. 

These active centres are available as anchoring locations to the coating, adhesive or paint system you wish to apply.

Plasma-coating

By introduction of monomers to the plasma process thin films are deposited on the surface giving the product new surface characteristics. The surface functionality (hydrophilic, hydrophobic, anti-fog, etc.) of the surface is determined by the type of monomer applied.

Plasma Primer surface coating

 See: Plasma or PVD coating

Plasma Primer

A new Plasma process for improving the adhesion of paints or adhesives. The surface of the product is activated prior to applying the adhesion promoting primer as a  plasma deposited

surface coating.

This efficient process combination greatly improves the bond strength between the product and the paint or adhesive system.
