1. Can the AG and AR process be realized on a cover glass?
AG, AR and AF can be realized on the same cover glass, called 3A. It is standard for display cover glass.
+
2. How much is IK08 equivalent to a drop ball test of glass?
+
3. What kind of processes can achieve the “dead front effect” of cover glass?
① Printing, small area within 20×20mm.
② Electroplating, suitable for sizes below 7 inches.
③ Gray glass material, max size 32 inches.
④ Film Adhesion, unlimited size.

4. What is the stress standard after glass chemical strengthening?
Corning Gorilla Glass Stress Value: DOL>40um, CS>650Mpa
Soda Lime Glass Stress Value: DOL>8um, CS>450Mpa
+
5. What is Dead Front Glass?
Dead Front effect (All-in-one-black): display visible when back-lit; completely black when non-backlit.
Widely used in smart homes, wearables, financial, medical, industrial control.
+
6. Will the glass strength be affected after AG etching?
No, etched surface depth ~0.05mm. Chemical strengthening is immersion type and not affected.
Time-tested; strength remains intact.
+
7. For AF (Anti-Fingerprint) coating, how much is the qualified water contact angle?
Gelivable standard water contact angle is >105°. Abrasion test: 200g weight, Steel Wool #0000, 2000 times (back and forth = 1 time), Recession Value within 15%.
+
8. How to recognize the etched side?
Hold the AG glass under a fluorescent light. Scattered light → etched side; clear light → non-AG side.
+
9. How many days to deliver custom cover glass?
Gorilla Glass 3, 4, 2320: 90% samples delivered within 7 days.
Mass production: ~15 days.
+
10. Specification Of Custom Gorilla Glass
Production info of Gorilla Glass 2320 & 4(5318).
+
11. What’s the unit of Haze?
Haze: % of incident light deviating >2.5° / total light. Higher haze → lower gloss & resolution.
+
12. Is it possible to print on the side of AG glass?
Both single and double side AG glass can be silkscreen printed.
+
