Surface activation and cleaning

Nadir Plasma is used for surface activation and cleaning of different materials: plastics, metals, textiles, ceramic materials and composite materials. The pre-treatment by Stylus Plasma ensures efficient cleaning and degreasing action thanks to the selective removal of surface contaminants, thus renewing the surface of the material of interest. Moreover, thanks to the high density of active species in the plasma generated by Stylus Plasma, the treated surface increases its surface energy (mN/m) assuming polar characteristics. Even highly non-polar plastic materials such as polyolefins find a particular affinity for water-based substances and compounds. Nadir Stylus Plasma is  the most appropriate surfaces pre-treatment of materials to be coated, printed, glued or laminated to another material.

Improved Wettability and overprintability

Nadir Stylus Plasma can be used to improve the surface wettability of a wide range of materials such as polymers, textiles, papers, wood, metals, ceramics, glass. The great versatility of Nadir Stylus Plasma ensures the  optimal balance between the effectiveness of the activation effect and the respect of the original base material, in particular in case of temperature sensitive materials.

Adhesion promotion and primer replacement

Nadir Stylus Plasma is a powerful tool for surface activation and sensitization  for adhesion promotion and for joining dissimilar materials. The flexibility of Nadir Plasma Stylus enables a multiple action on the surface. First is possible to promote adhesion by enhancing surface wettability and by obtaining a superior spreading of the adhesive on the surface. Then, advanced surface modifications are achievable by grafting chemical species and functionalities  for adhesion promotion with the desired joint. Nadir Stylus Plasma is also used in the deposition of organic and hybrid super-thin layers that allow the replacement  of common solvent-based primers,  guaranteeing the desired adhesion performance with environmentally friendly and solvent-free processes.

By partnering with Veneto Nanotech ScpA,  some processes of plasma assisted surface functionalization were developed promoting the adhesion between dissimilar materials in epoxy, acrylic and urethane joints.

Surface protection

Nadir Stylus Plasma is also used as a tool for the controlled and localized deposition of  transparent protective films. These protective layers are especially suitable for the protection of logos, or other sensitive parts of the product of interest, from chemicals and abrasive parts.

Water repellent surface finishing*

Nadir Stylus Plasma is used for the deposition of water-repellent coatings, also applicable to the more delicate materials and the textile industry. Thanks to the ease of use of Stylus Plasma, it is possible to act selectively on the parts of interest, also on three-dimensional products.

* This deposition process has been developed in collaboration with Veneto Nanotech SCpA

Photocatalytic self-cleaning coating *

Nadir Stylus Plasma is used in the deposition of photocatalytic self cleaning coatings based on titanium dioxide, known catalyst able to degrade numerous organic compounds with the help of sunlight. The photocatalytic coatings obtained by Stylus Plasma are used as self-cleaning coatings capable of degrading dirt and toxic pollutants.

Degradation of an organic compound (stearic acid) on photo catalytic coating exposed to UV radiation.

The photocatalytic coating obtained by mean of Nadir Stylus Plasma is also used as  UV filter for protection and maintenance of the original color of objects exposed to solar radiation.

* This deposition process has been developed in collaboration with Veneto Nanotech SCpA

Transparent and flexible conductive coating

Nadir Stylus Plasma allows to make conductive the treated surfaces while maintaining transparency and flexibility in the case of dealing in sheets of polymeric material. The deposition process has been developed in collaboration with Veneto Nanotech SCpA, and is applicable by mean of Nadir Stylus Plasma  to impart antistatic properties on treated surfaces of the materials of interest.
