Our Fine Hard Mat™ solution has the same excellent durability and scratch resistance as Cleartech™ but with an additional anti-glare surface treatment.
Fine Hard Mat™ achieves this by having a tough surface treatment with anti-glare properties. Its double-sided hard-coated acrylic material makes the surface hardness among the best on plastics.
Do you not know what the difference is between anti-glare and anti-reflection? If so, feel free to read our article about the subject by clicking here.
The anti-glare hard coat is optimized for modern industrial displays as it is dirt- and smudge-repellent and very easy to clean. This solution also has very low finger drag resistance optimized for touch applications.
Because of the durability of Fine Hard Mat™, it is perfect for displays used under challenging conditions daily that require anti-glare properties.
