Real-World Application
Lab Impressions
Coating conformity
SEM picture of a silicone sample broken in two to display the conformity of the coating (thin whiter line around the substrate). It adheres so well to the surface that it holds the two pieces of Si together.
Structural integrity
We are dedicated to respect the finest structures of your high-value devices.
Surface Energy
Surface energy is crucial in material science because it determines the way a material interacts with its environment.
High surface energy enhances the bonding strength with adhesives and paints, leading to more durable and reliable products in industries ranging from automotive to construction.
Proven technology
Evidence-based surface technologies enable the creation of advanced solutions that meet stringent industry standards and customer expectations.

The plasma coating can reduce protein adhesion, which is the initiator of immune system reactions. Thus, it can be used to camouflage implants in the body. Because the coating has a long term stability, its effect is retained over a long period.
