Diamondshield® is part of the family of patented diamond-like carbon (DLC) and related superhard coatings from MTC Diamonex, the world leading developer and supplier of diamond-like coatings. Diamondshield® has extreme diamond-like properties of high hardness, optical transparency, high chemical and electrical resistance, elasticity and low friction.
Whether optical performance or cosmetic appearance is important Diamondshield® has exceptional transparency, even at a 10-micron thickness on multi-dimensional parts. With a very low index of refraction and virtually no absorption in the visible, Diamondshield® is the ideal performance and appearance enhancing coating.
Plastics or soft materials are ideal for many applications but these materials suffer functionally and cosmetically from poor wear resistance. Diamondshield® provides previously unattainable abrasion resistance, equal to that of bulk glass, enabling high-load durability to traditionally damage-prone materials.
