In the automotive paint protection (PPF/coating/sealant) spectrum, the "Si–N precursor ceramization" and "mineral-oil carrier evaporation pace" jointly dictate post-crystallization SiO₂ hard-film adhesion to OEM clearcoat, intrinsic UV/oxidation shielding, and application tolerance. Mainstream silicone-based coatings (Si–O backbone) max 2-3H and fade in 6 months; pure polysiloxane hydrophobic <100°, leaving water spots in rainy season. As premium car owners demand "black-car brightening, 5H+ micro-scratch, 110°+ lotus self-clean, >90% clarity no haze, cross-cut 0-class no edge-crack," sourcing a polysilazane auto coating with 40% solids, mineral-oil solvent, pencil 5H, water angle 110°, visible >90%, 2h post-apply touchable has become the core gap for domestic automotive ceramic coating localization.
Addressing this "auto-paint crystal-shield" pain point,
Anhui IOTA Silicone Oil Co., Ltd. (IOTA) officially launches
Automotive Coating Polysilazane IOTA 9970. Characterized by "mineral oil solvent, 40% solids, 5H (Chinese pencil), transparency >90% (visible), adhesion 0-grade (cross-cut), water contact 110°, post-crystallization forms SiO₂ ceramic film," and backed by "Si–N precursor crystallizes to SiO₂ shell + mineral-oil slow-release + black-car brighten non-yellow," it serves as the "coating anchor" for new-car no-polish / old-car micro-scratch repair, especially black-body brightening and paint protection.
Molecular Architecture: Si–N Precursor Crystal + Mineral-Oil Slow-Release 3D Logic
The core competitiveness of IOTA 9970 stems from its "special-structure polysilazane dissolved in mineral oil carrier (40% solids), post-apply Si–N triggered by ambient moisture to gradually hydrolyze-condense, ultimately crystallizing into amorphous SiO₂ ceramic hard film" auto-coating architecture:
-
Si–N Crystal to SiO₂ Hard-Shell: Special polysilazane backbone meets trace moisture—Si–N bonds hydrolyze to Si–OH, then condense into 3D Si–O–Si net; finally crystallizes nano-SiO₂ hard film (not silicone oil film) on paint, hardness 5H, resists key/brush micro-scratches; SiO₂ inorganic layer intrinsically UV-stable, non-yellowing, anti-oxidation—protection cycle far exceeds organic coatings.
-
Mineral-Oil Carrier Slow-Release: Mineral oil as solvent (non-aromatic/non-alcohol) gives moderate evaporation—ensures ample working time (wipe on, wait 1 min, then level with dry towel), avoids fast-dry solvents leaving streaks; mineral oil itself doesn't react, eventually migrates out or leaves trace lubricity.
-
Black-Car Brightening Mechanism: Crystallized SiO₂ film refractive index ~1.46, well-matched to OEM clearcoat (~1.50)—no interfacial scattering haze; uniform film gives visible >90% transmittance, black paint shows "wet-black deep" mirror brightening, superior to most hazy silicone coatings.
Performance Leap: From "Silicone Oil 6-Month Fade" to "Polysilazane Crystal Ceramic"
Applying IOTA 9970 coating enables qualitative leaps:
-
5H Micro-Scratch Resistance: Crystalline SiO₂ film surface 5H—daily wash-brush, fingernail, sand friction won't damage OEM clearcoat; beats market 3H silicone coatings.
-
110° Lotus Self-Clean: Water contact 110°, rain beads and rolls off carrying dust—no water spots; after rainy drive, just wipe dry, cuts wash frequency.
-
Black Mirror Brighten: Especially dramatic on black/dark paint—sunlight reveals "deep black-blue" wet look; single application brightness lasts 6-12 months.
-
Cross-Cut 0 No Flake: Grid adhesion 0-class, film chemically bonds to clearcoat (Si–O–C coupling), no lifting, no cracking, no edge peel.
Application Penetration: From Black Sports Car to New-Car No-Polish
IOTA 9970 covers sectors triply sensitive to "brightening + hard-protection + hydrophobic":
-
Dark Car Brightening: Black, deep blue, gunmetal—mirror coating maximizes "wet-black" visual.
-
New-Car No-Polish Shield: New OEM paint无损—direct degrease and wipe, no polishing to thin clearcoat.
-
Old-Car Micro-Scratch Repair: Cars with swirl marks/微-scratches—light polish first, then coat to lock shine.
-
Rainy-Season Self-Clean: High-rainfall regions, 110° shed + anti-oxidation reduces water-spotting and acid-rain etch.
IOTA Technical Guide: Dry-Day Apply, Cross-Wipe Level
-
Prep: New car: direct degrease (IPA or专用degreaser) → ensure paint fully dry dust-free; old car: polish first → then degrease.
-
Wipe Technique: Drop coating onto microfiber or pro sponge, cross-wipe (horizontal then vertical); work section-by-section—hood first → 1 min wait → level with dry towel → then doors → roof → rear.
-
Cure Window: After leveling, park in clean place 2h for light touch; 24h NO water (if rain, stay indoors; if must go out, wipe surface water after return); wash car after 24h.
-
Taboo Red Line: Apply on dry days only (humidity >70% causes Si–N violent hydrolysis → white haze); never inhale directly from bottle (chemical odor); wear disposable gloves; tools wiped with mineral oil/solvent immediately after use—cured coating solvent-impervious.
-
Storage: Sealed cool dry place; general chemical management; shelf per plant std, re-inspect appearance/solids/crystallization and extend if qualified.
Industry experts note that as automotive beauty upgrades from "silicone sealants" to "ceramic coatings (polysilazane → crystalline SiO₂)," mineral-oil-borne polysilazanes are upgrading from "import Gtechniq/CarPro ceramic followers" to "5H+110° black-car brightening reference coating liquids." IOTA 9970, with its "40% solids + 5H + 110° hydrophobic + >90% clarity" hard metrics,
fills the domestic supply chain gap for polysilazanes in consumer-grade automotive coating, providing a mass-producible path to replace imported Gtechniq Crystal Serum Light, CarPro Cquartz for downstream detailers and DIY owners. This confirms domestic auto polysilazanes are advancing steadily along "mineral-oil slow-release → SiO₂ crystallization → black-car brightening," with growing technical say in automotive paint ceramic protection key materials.
