Low Pressure Plasma Polymerization System

 Plasma Polymerization system characteristics (IONVAC Process s.r.l.)

The plasma polymerization deposition system allows the deposition of a wide range of polymer-like functional films which chemical composition depends on the liquid monomer precursors: Acrylic Acid; Styrene; DiethyleneGlycoleDimethylEther; organosilanes; organosiloxanes; etc.
