Custom ITO & Hydrophobic Coated Glass
Precision functional coatings for optoelectronics, industrial displays, and sensitive instrumentation. We combine transparent conductive Indium Tin Oxide (ITO) with highly durable anti-fingerprint (AF) treatments to solve complex surface challenges.
Verified Performance Specs:
- Water Contact Angle: > 110°
- Min. Sheet Resistance: < 10 Ω/sq
- Visible Light Transmission: > 88%
- Precision Layer Control: 0.6μm
- Enhanced Hardness: 1H-9H
Solving Dual Challenges: Conductivity Meets Durability
Touch interfaces and optical windows often require two conflicting properties: electrical conductivity and environmental resistance. Our thin-film deposition capabilities allow us to integrate both into a single substrate without compromising optical clarity.
Hydrophobic / Oleophobic (AF) Treatment
Applied at the nanometer scale, this surface energy modifier prevents liquid adhesion and smudging.
- Repels water, oils, and industrial fluids
- Drastically lowers friction for smooth touch interactions
- Survives 10,000+ heavy steel wool abrasion cycles
Indium Tin Oxide (ITO) Deposition
Highly uniform TCO (Transparent Conductive Oxide) sputtering that delivers reliable electrical pathways with minimal optical loss.
- Dial-in sheet resistance targeting (10Ω to 500Ω/sq)
- Proven EMI/RFI shielding effectiveness
- Stable performance for transparent heaters and sensor grids

Our Deposition Process
Consistency is everything in thin-film coating. Here is how we control quality from raw material to finished optic:
- Plasma Cleaning: Deep ion-bombardment to strip microscopic contaminants and ensure atomic-level adhesion.
- Magnetron Sputtering (ITO): Applying the conductive layer under vacuum with real-time resistance monitoring.
- Thermal Annealing: Heat treatment to lock in the crystalline structure, maximizing both transparency and conductivity.
- Vacuum Evaporation (AF): Depositing perfluoropolyether molecules to create the dense hydrophobic barrier.
- Quality Control: Verifying ohms per square via four-probe testing and measuring contact angles with a goniometer.
- Cleanroom Packaging: Final inspection and static-safe sealing for global transit.
