Custom Chemically Strengthened Etched AG Glass Panels
Product Overview
Chenshi Tech specializes in the precision manufacturing of custom chemically strengthened etched AG glass panels and high-definition anti-glare display cover glass. By utilizing advanced chemical dipping and micro-etching processes directly on the glass surface, our etched anti-glare glass eliminates harsh reflections, reduces ambient glare, and provides a silky-smooth tactile touch experience without the particle-shedding or peeling risks associated with spray-coated alternatives.
Complementing our precision conductive glass and high borosilicate glass panels, our custom chemically strengthened etched AG glass panels deliver the rugged impact resistance and optical clarity required for automotive cockpits, medical touchscreens, military displays, and industrial control consoles.

Key Advantages of Chemical Etched AG Glass Panels
-
Permanent Monolithic Structure: Chemical etching modifies the glass surface itself by reacting acid solutions with silica, creating microscopic crater-like diffusion textures. Unlike spray-coated anti-glare coatings, etched AG glass will never peel, flake, degrade, or scratch off during continuous wiping and harsh chemical cleaning.
-
Elimination of Visual Sparkle: Coated AG often creates severe color sparkling and pixel blur on high-resolution displays. Our proprietary etching process controls particle grain distribution to under 15 microns, maintaining sharp text rendering and high dynamic contrast.
-
Smooth Paper-Like Tactile Touch: The uniform micro-texture provides an exceptional touch feel with zero finger friction or drag, making it the premier choice for active stylus handwriting panels and capacitive touch screens.

Frequently Asked Questions (FAQ)
Q: What is the main operational difference between Etched AG Glass Panels and Spray-Coated AG Glass?
A: Etched AG glass is produced by chemical acid immersion that reshapes the glass surface directly into permanent microscopic scattering structures. It will never wear off, bubble, or peel over time. Spray-coated AG relies on polymer resin films that can easily wear off under repeated touch friction, cleaning agents, and outdoor weathering.
Q: How do I choose the correct Gloss Level and Haze for my display?
A: Gloss and haze are inversely correlated. For high-resolution screens (such as 4K medical panels or automotive dashboards), a high-gloss, low-haze specification (such as Gloss 70 to 95 GU, Haze 3% to 8%) is recommended to eliminate sparkle and preserve high contrast. For outdoor terminals exposed to strong direct sunlight, a lower gloss level (Gloss 35 to 50 GU, Haze 10% to 18%) provides maximum reflection diffusion.
Q: Q: Can custom chemically strengthened etched AG glass panels be combined with AR and AF coatings?
A: Yes. We frequently manufacture triple-effect “AG + AR + AF” cover glass panels. Etched AG scatters ambient light, AR maximizes light transmission from the display beneath, and AF ensures a smooth, smudge-resistant, easy-to-clean surface.
Q: What impact standards can chemically strengthened cover glass pass?
A: Depending on the substrate material and glass thickness, our panels comply with IK07, IK08, and IK09 impact ratings, easily passing 500-gram steel ball drops from heights of 1.0 to 1.5 meters without structural failure.
