Hydrophobic Coating Glass: water contact angle > 110 degrees. Single-piece prototypes to production volumes, quoted from your drawing.
Specify hydrophobic coating glass when the bare substrate falls short: fluorosilane easy-clean layer, processed by vapor-phase silanization, brings the substrate you specify to water contact angle > 110 degrees.

Getting the drawing right
Before sending the RFQ, check these against your drawing:
- Sequence matters: all machining happens before hydrophobic coating; post-coating rework is not economical.
- Over-specification is the quiet budget killer: a 20/10 scratch-dig face costs roughly three times an 80/50 face, so grade each surface individually.
For the complete framework, see the tolerance design guide and the holes and edges design guide.
Application context
hydrophobic coating glass shows up across aerospace optics (sensor windows, star-tracker flats, radiation-tolerant ports); ccd inspection equipment (CCD cover plates, reference grids, stage glass); scientific instruments (reference flats, cells, prism mounts, stage inserts).

Frequently asked questions
Do parts ship with inspection data?
Dimensional reports, surface certificates and material certs per melt are available; specify the level on the RFQ.
What does hydrophobic coating add?
Sheds water and fingerprints on touch faces. Applied by vapor-phase silanization to water contact angle > 110 degrees.
Is there a minimum order for hydrophobic coating glass?
No. Single prototypes are accepted, and pricing steps down at 10, 100 and 1,000 pieces.
How fast can prototypes ship?
Machined prototypes ship in 5 – 10 working days. Coated or bonded parts add 1 – 2 weeks depending on queue slots.
What files do you need for a quote?
A dimensioned PDF plus DXF or STEP geometry. If only a sketch exists, our drawing review service formalizes it before quoting.
