Several years ago, Dontech expanded its thin film coating offerings to better serve the high-performance flexible film market. We now offer toll coating services to a broad range of high reliability and performance markets. This initiative was supported by our experienced design and production team, which has been producing optical filters and components which enhance the performance of high-end optical information displays, touch screens and precision optics so they perform as desired in demanding environments for more than 50 years.

We are unique in the industry. Our roll-to-roll thin film coating offerings are supported by our experience with complex, batch, thin film coatings and a broad range of thick film (e.g., hard coatings) gained from servicing high-reliability applications in the military, medical, and avionic markets. When needed, we can rapidly prototype complex designs in batch systems and transfer them successfully to a roll-to-roll process.

Our physical vapor deposition (PVD) process offerings include AC and DC magnetron sputtering, ion-enhanced E-beam evaporation, plasma-enhanced chemical vapor deposition (PECVD), and chemical vapor deposition (CVD). Other vacuum roll-to-roll services include plasma treatments of base substrates for improved adhesion and surface functionalization. Coatings can be applied to one or both surfaces of flexible substrates including a broad family of plastics with and without thick film hard coatings and metal foils. These coatings improve optical, electrical, and environmental substrate properties.
