Graphene Coating

A graphene coating is similar to a ceramic coating, but uses carbon in the form of graphene sheets instead of silica dioxide.

What it means

Most automotive “graphene” coatings are polysiloxane/SiO₂ systems modified with graphene-oxide (GO), reduced GO or other carbon dispersions. The cured film is transparent and hydrophobic, aiming to refine slickness and water-spot resistance. Real, continuous graphene monolayers require industrial deposition processes and cannot be achieved by wiping on a liquid.

Why it matters

• Expectation setting: performance depends on full formulation, prep and conditions - not the word “graphene”.
• Maintenance: behaves like a ceramic: easier cleaning, tuned beading or sheeting, periodic toppers still help.
• Positioning: often sold as a premium variant of consumer ceramics with claims around slickness or spotting.

Where you’ll see it

Retail “graphene ceramic” sprays or wipe-on coatings, some detailer offerings, and dealer packages using graphene branding.

Context

Car Paint Protection; Ceramic coatings; Marketing claims

Common mistakes

• Taking “graphene” literally - wipe-on liquids cannot lay a true graphene sheet on paint.
• Assuming unique immunity to water spotting - prevention still relies on technique, DI/RO rinse and prompt drying.
• Expecting scratch-proof or chip resistance - behaviour is similar in kind to other ceramics, not PPF.
• Skipping decontamination, polish and panel wipe - poor prep leads to high spots and weak bonding regardless of label.
• Using on windscreens where wiper judder is likely - use a dedicated glass coating if needed.
