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.

Design guidance
Three items decide most of the cost and lead time on this work:
- 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
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.
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.
