From the manufacturer’s Safety Data Sheet, Section 8
“No H319 or H318 at mixture level in SDS §2. The product is applied wipe-on with an applicator pad — not pump-sprayed — but the 12 °C flash point and high volatile fraction make solvent vapor a real presence in the cabin during application. The enclosed-space trigger captures the cabin-vapor pathway during wipe-on application.”

From the manufacturer’s Safety Data Sheet, Section 8
“No H315, H317, or H314 at mixture level in SDS §2. Wipe-on application with an applicator pad means direct hand contact with the saturated pad is the realistic pathway. Naphtha and Stoddard solvent are documented defatting agents on prolonged or repeated skin contact — the situational tier reflects the wipe-on application method, not an acute irritation classification.”

From the manufacturer’s Safety Data Sheet, Section 8
“No H335, H331, or H334 at mixture level in SDS §2. H336 (drowsiness/dizziness via CNS, STOT SE Cat 3) is present but the product is applied wipe-on — the pump-spray ×1.25 modifier does NOT apply. H372 (STOT RE Cat 1) reflects organ damage from prolonged or repeated occupational exposure, not a single home application. SDS §8 explicitly states 'breathing protection is not required' under correct and proper use. The 12 °C flash point and high VOC fraction make cabin vapor a real-but-bounded exposure during wipe-on application in an enclosed cabin — situational with enclosed_space captures the practical risk.”

CarCareTruth's Analysis
Last reviewed May 19, 2026
TL;DR Non-PFAS textile coating applied wipe-on with an applicator pad — not pump-sprayed. Community durability evidence is thin and Gyeon's "months of protection" claim is not corroborated by time-stamped reviews. DANGER from a solvent-base carrier: H304 aspiration and H372 organ-damage risk on prolonged exposure.
What it is and how it performs
Q² Fabric Coat applies wipe-on with a saturated applicator pad to clean dry fabric, flashes off, and cures into a hydrophobic barrier on upholstery, carpet, and convertible tops. The 98-review Amazon corpus notes initial beading but does not document controlled multi-week durability; no r/AutoDetailing or AutogeekOnline threads track the window with time-stamped follow-ups. Plan reapplication well before the marketing implies.
Who should buy this — and who should skip it
A fit for Gyeon-system detailers who want a non-PFAS coating that integrates with the Q² line and prefer a wipe-on workflow. Skip it for Alcantara or suede without spot-testing — the solvent-base carrier risks compatibility on delicate napped fabrics. Buyers needing durability evidence should wait for more community data.
Safety and environmental impact
The PPE tiers are translated from the GHS classifications and ingredient chemistry — not from SDS Section 8 boilerplate.
DANGER is driven by H304 (aspiration if swallowed) and H372 (organ damage on prolonged solvent-base exposure). H226 (flammable Cat 3) is a physical hazard and does not contribute to health. H336 (drowsiness or dizziness) is present, but the wipe-on method means the pump-spray modifier does not apply. SDS §3 confirms no fluorinated compound — non-PFAS, a positive distinction relative to fluoropolymer-based protectants. Environment reflects the high-VOC carrier (~620 g/L) and a non-biodegradable carrier fraction.
Frequently asked questions
Is Gyeon Q² Fabric Coat PFAS-free?▾
Yes. SDS Section 3 (Rev 5.0, dated 2024-04-30) discloses the full ingredient set down to 1%: naphtha and Stoddard solvent as carriers, a titanate active, plus xylene and an octylene-glycol co-solvent. No fluorinated, fluoropolymer, fluorotelomer, or perfluoroalkyl compound is disclosed. The chemistry is confirmed non-PFAS based on the SDS ingredient list, not just a label claim.
Is Gyeon Q² Fabric Coat really a ceramic SiO₂ coating?▾
The Amazon listing markets a 'durable ceramic SiO₂ barrier' but SDS §3 discloses a titanate active (titanium tetraisopropanolate, CAS 546-68-9) at 3–<7% — not a silica fraction. The 'ceramic' language is marketing positioning for the metalate crosslinker chemistry, not a confirmed silica-based formulation. Buyers comparing this to silica-based ceramic coatings should treat the SiO₂ marketing claim as unverified.
How is Gyeon Q² Fabric Coat applied?▾
Wipe-on with an applicator pad — not pump-sprayed. Per Gyeon's documented installer method: saturate a microfiber or foam applicator pad with the liquid, apply evenly to clean dry fabric, allow to flash off, and cure undisturbed. The 4.06 fl oz bottle covers a moderate interior; the 13.53 fl oz size covers larger jobs. Apply with vehicle doors open — the 12 °C flash point and high solvent VOC make full ventilation important even though the application method is wipe-on rather than spray.
Why does Gyeon Q² Fabric Coat have a DANGER label?▾
Two GHS health-hazard classifications drive the DANGER signal word: H304 (may be fatal if swallowed and enters the airways — an aspiration hazard, not an inhalation hazard during normal application) and H372 (organ damage from prolonged or repeated exposure to the Stoddard solvent and naphtha carrier fraction). H226 (flammable liquid Cat 3) is a separate physical-hazard classification. Neither H304 nor H372 reflects an acute inhalation risk from a single home application — they are honest chemistry disclosure for the petroleum-solvent carrier.
How long does Gyeon Q² Fabric Coat protection last?▾
Long-term community evidence on this specific product is thin as of 2026-05-18. Gyeon's marketing claims 'months of UV and stain resistance,' but no multi-month durability tracking threads on r/AutoDetailing or AutogeekOnline document the protection window with time-stamped follow-ups. The Amazon review corpus (98 reviews at 4.2 stars) notes initial beading but does not contain controlled multi-week durability documentation. Plan for reapplication well before the label claim until more community data accumulates.
