Advantage
and Value
Benefits of Transient Plasma Surface Treatment System:
Ideal for treating sensitive substrates like textiles as well as medical applications like wound sterilization
Low sensitivity to working distance makes it suitable for coating uneven surfaces including printed circuit board assemblies
Precise control of plasma energy enables soft fragmentation of complex molecules like HMDSO, APTMS, AGE etc. resulting in high integrity functional thin film coatings for applications such as:
Medical devices like drug-eluting stents, interventional catheters
Thin functional coatings for diagnostic tools like lab-on-chip
Adhesion promoting film replacing wet chemical primer in industrial adhesive bonding applications

with Transient Plasma Systems Enables:
Effective functionalization of even temperature sensitive substrates like EPDM and difficult to activate substrates like silicone
No changes to surface topology leading to better adhesion
No particle deposition
SEM pictures taken from an EPDM surface before and after treatment by Transient Plasma show no significant change on the surface topography.
EPDM Surface BEFORE
EPDM Surface AFTER
Bonding result force/way plots for both versions of EPDM (non-activated and activated by plasma) with the difference in elongation.
For activated EPDM, bond strength is not limited by adhesion, but by material strength of EPDM (rupture on elongation).
WITHOUT (TPS) Transient Plasma Treatment
Bonds Break at <100N of Force
WITH (TPS) Transient Plasma Treatment
Bonds Hold at >200N of Force
Surface Coating
with Transient Plasma Systems Enables:
with Transient Plasma Systems Enables:
