Depending on your requirement, there are two specialty fluids available for glass coating : 3M Novec 1720 and Solvay’s Fluorolink S10.

3M™ Novec™ Glass Coating – Novec 1720

Easy clean glass coating is designed for device surfaces to keep them looking good and functioning properly; they impart an anti-smudge, easy to clean surface for anti-reflective (AR) flat panel displays; pellicles; MEMS; fibre optics and other glass and glass-like surfaces. The ultra-thin coating is applied by spray or dip application to a device surface for consistent, full coverage.

• Low viscosity and surface tension make it exceptionally thin (less than 10 nanometers)
• Optically transparent so not affecting the look of the device
• Thermal curing adds chemical and abrasion resistance
• Hydrophobic and oleophobic: Excellent repellency for quick and easy clean-up of the surface from a variety of contaminants
• Anti-smudge: Resists accumulation of fingerprints, oils, liquids, grime and cosmetics
• Improved lubricity: Makes the surface feel smooth and appealing
• Low global warming potential (GWP) solvents and zero ozone depletion potential (ODP)
• Exempt from the U.S. EPA definitions for volatile organic compounds (VOCs)
• Not scheduled for regulatory phasedown or phase-out
• Low in toxicity gives a wide margin of worker safety
• Non-flammable and Non-conductive

Fluorolink S10

Fluorolink S10 is a triethoxysilane terminated, bifunctional PFPE used as a surface treatment for glass, siliceous surfaces, metals, and any substrate having -OH groups available on the surface.

A thin layer of Fluorolink S10 imparts outstanding water and oil repellence, friction reduction and antisticking properties to the treated surface and in addition, Fluorolink S10 has a low refractive index and a good resistance to weathering, solvents and abrasion.

Samples and trials of glass coatings materials are available on request.
