DiamondShield® Coatings™
MTC Diamonex DIAMONDSHIELD® is the premier abrasion-resistant coating for soft substrates such as plastics .
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.
Transparency
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.
Durability
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.
