The Surface Activation process by means of the Plasma technique is effective in that it allows to modify the surface of a polymer allowing functional polar bonds to it.
Various kinds of polymers such as polyolefins, polyethylene and polypropylene would be chemically inert without therefore the ability to obtain effective bonds with other materials; this normally causes repellency, given the poor adhesion, with inks, paints and glues. The reason is due to the ineffective surface tension due to the intrinsic values of the material due to the absence of polar and reactive functional groups in the structure of the polymer that composes it.
The Surface Activation procedure thanks to the application of the plasma creates activity and receptivity of polymers with binding agents and external coatings.
The "activated" material is effective even for a very long time (months), this depends on the type of material and on the conditions of handling and post-treatment conservation. It is very significant to consider that materials such as polypropylene allow even repeated processes after a initial initial treatment and even processes can be carried out in the dusty or grainy state of the material, allowing functional efficacy even after casting.
The main functions:
- hydrophilicity
- hydrophobia
- bonds between polymers, activity and receptivity to binding agents and external coatings
- bonds with different substances and materials
