Technology & Innovation
Four foundational technologies power every Stone Tec product.
Self-Healing Technology
Tested with a rising-temperature method — minor scratches fully disappear within minutes.
Our top-coating chemistry uses cross-linked polymer chains that rebond after disruption. Everyday micro-scratches from washing, debris, or accidental contact heal automatically with ambient warmth. In colder conditions, mild heat (a warm cloth or sunlight) accelerates the recovery.
Hydrophobic Top Coat
High-angle beading keeps the film clean and reduces chemical exposure time on the surface.
Hydrophobic coatings cause water to bead at high contact angles, rolling off the film instead of evaporating on the surface. This shortens the dwell time of contaminants, road salts, and tree sap — reducing risk of etching and making routine cleaning faster.
Nano Ceramic Technology
Non-metallic, non-conductive layers — no interference with GPS, mobile, or radio frequencies.
Our window films use multi-layer nano-ceramic particles suspended in a durable polyester carrier. The particles reflect and absorb infrared wavelengths while remaining transparent to visible light and wireless signals — delivering high heat rejection without dyes or metal.
UV & Weather Resistance
3000 hours of accelerated weathering with virtually no color change.
Our UV stabilizers are integrated through every layer — not just the top coat. After 3000 hours of QUV accelerated weathering, measured color shift stays below ΔE 2, meaning the film remains visually unchanged for many years of real-world exposure.
Independently tested to five industry standards.
Every batch audited against ASTM, GB/T, and SAE specifications — with performance documentation available to certified installers.
