Coating Science: What's Actually in a Ceramic Spray Coating

Or: graphene, Triphene, SiO2, ceramic — what the labels are really saying.

I'm Sean, the founder of Luma Auto. I make this product, so I'll tell you what's really in it. Most of the car care industry won't.

The honest answer

Almost every "ceramic spray coating," "graphene coating," or "Triphene-powered" spray on the shelf is the same family of chemistry: an organosilane self-assembled monolayer, or SAM coating.

Translation: a special kind of silicon-based molecule with two ends. One end bonds to your paint, glass, or plastic. The other end faces outward and repels water. When you spray and wipe, the molecules line themselves up like dominoes and create a thin protective layer.

This chemistry has been around for over a decade. The brands aren't competing on different chemistries — they're competing on different trademark names for the same chemistry.

What's in Luma Graphene

I'm going to show you, because we publish our Safety Data Sheet. Other brands don't.

• Water — 85–90%
• Silane polymer (cyclosilazane with triethoxysilyl-propyl reaction products) — 1–5%. This is the active ingredient. It's the molecule that bonds to your surface and creates the hydrophobic layer.
• Butoxy isopropanol — 1–2%. A coupling solvent that helps the silane spread evenly.
• Octamethylcyclotetrasiloxane (D4) — 1–2%. A silicone fluid that adds gloss and smoothness.
• Light petroleum distillate — under 1%. A carrier solvent.

That's the whole bottle. No mystery ingredients.

So is there actual graphene in it?

Honest answer: graphene (the carbon material that makes news headlines) is not what's doing the work in any "graphene coating" spray on the market — ours included. The active chemistry is the silane. "Graphene" is a marketing name the industry settled on around 2020, the same way "ceramic" became one around 2015.

We use the name because it's what the category is called. But we're going to tell you what's actually doing the work. The silane is doing the work.

What about MAXL's "Triphene"?

MAXL describes Triphene on their own help page as "a triple-layer that self-assembles on a surface upon contact. Two layers crosslink and bond to the surface, the outer third layer is a wax-like tail structure."

That description is the textbook definition of an organosilane SAM coating. Same family of chemistry as ours. Triphene isn't a chemical compound — it's a trademark name MAXL coined for their version. They don't publish a Safety Data Sheet, so I can't tell you the exact silane they're using. They're allowed to keep that confidential. We chose not to.

So which one is better?

For honest performance: in independent side-by-side tests, products in this category mostly perform within 10–20% of each other on water beading and gloss. The differences come from the specific silane tail (some use fluorinated silanes, some use silicone-based tails), the concentration of the active ingredient, and how clean your surface was when you applied it.

Where the meaningful differences show up is fitness for purpose. A product designed to coat your kitchen sink, patio chairs, and car (MAXL's positioning) is making a different trade-off than a product designed specifically for EV interiors and exteriors (ours).

We made Luma Graphene to be safe on the surfaces a Tesla or Rivian owner actually touches every day: PPF, ceramic-coated paint, vegan leather, touchscreens. Heat-stable. No solvents that attack tint or screen oleophobic coatings. That's the trade-off we picked.

If you just had PPF or window tint installed

The wrong aftercare product can undo a $3,000–$7,000 install. Ammonia destroys tint film. Acidic cleaners eat through PPF self-healing topcoats. Even "ceramic coatings" not designed for film can leave residue that traps dirt under the surface.

Luma Graphene is built around the chemistry your installer cares about: no ammonia, no acids, no aggressive solvents. The silane bonds to the top layer of your film without penetrating the adhesive. If your installer applied a professional ceramic coating on top of your PPF, this spray is what extends its life between detailing visits — it's compatible with virtually every pro topper on the market.

Same applies to interior film and window tint: ammonia-free Glass Cleaner, vegan-leather-safe APC, screen-safe trim dressing. The whole line is built for film-protected vehicles.

If you install PPF, window tint, or ceramic coatings professionally — and you want a US-made aftercare product line you can offer customers without worrying about your warranty, get in touch. We work with shops on wholesale pricing, referral commission programs, and complimentary kit drops for installers who want to test before recommending.

Why we publish our SDS

You can ask any car care manufacturer for their Safety Data Sheet. They're required by OSHA to provide it. Most won't, unless you push. Many never write one that has real ingredient detail — they put "proprietary blend" and call it done.

We publish ours because if you're going to spray something on a $80,000 vehicle and breathe the mist while you do it, you deserve to know what it is. That's it.

If something here doesn't match what you've been told about ceramic coatings — fair. Ask us. We'll show you the chemistry.
