Hard Coatings for Eyeglass Lenses

Hard Coatings are advanced protective coatings applied to surfaces to improve
their resistance to scratches, abrasion, and wear. These coatings form a hard,
durable layer on the substrate, making it resistant to mechanical damage and
external elements such as chemicals, UV radiation, and moisture.
Key Characteristics of High-Quality Hardcoats
For a hardcoat to provide effective protection, it must possess several
critical characteristics:
Scratch and Abrasion Resistance: The primary function of hardcoats is to
protect surfaces from scratches, scuffs, and abrasion during regular use or in
harsh environments.
Chemical Resistance: Hardcoats provide a barrier against solvents, acids, and
other chemicals, ensuring the substrate remains intact and performs well over
time.
UV and Weather Resistance: Hardcoats designed for outdoor applications should
resist UV radiation and weathering to prevent yellowing or degradation when
exposed to sunlight.
