iDLC Coatings
Umicore was the first to pioneer a DLC performance coating on chalcogenide glass. This is an extremely rugged and abrasion resistant anti-reflection coating, making it ideal for external surface applications where extreme environmental conditions will be encountered. Umicore can successfully apply iDLC coatings to its range of proprietary GASIR® chalcogenide glass.
Below is a table showing the typical specification of Umicore’s iDLC coatings.
