Quick answer: FTO Coating Glass covers 7 – 15 ohm/sq, stable to 600 C. Prototypes ship in 5-10 working days.
Specify fto coating glass when the bare substrate falls short: fluorine-doped tin oxide, processed by spray pyrolysis on float line, brings the substrate you specify to 7 – 15 ohm/sq, stable to 600 C.

DFM notes from the shop floor
Before sending the RFQ, check these against your drawing:
- Sequence matters: all machining happens before fto 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.
The full rules live in our tolerance design guide and holes and edges design guide.

Common 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 fto coating add?
Heat-tolerant conductive layer for cells and heaters. Applied by spray pyrolysis on float line to 7 – 15 ohm/sq, stable to 600 C.
Is there a minimum order for fto 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.
