product details
Introduce our products
A patent-finish polyurethane synthetic leather with alligator-scale embossing, delivering a wet-look high-gloss surface with deep-drawn hexagonal scale patterning for luxury goods and fashion applications. The material is engineered with a cross-linked PU topcoat on a knitted carrier, providing peel adhesion ≥30 N/3cm, tensile strength ≥350 N/5cm, and gloss retention of 90 GU minimum after 500-hour UV exposure. Solamni supports custom scale dimensions, embossing depth to 0.4mm, and low-temperature flexibility to -10°C.

Solamni operates an ISO 9001:2015-certified laboratory. Validation protocols for shiny alligator patent PU leather focus on gloss stability, scale depth retention, and adhesion resistance under flex fatigue.
Coating Adhesion & Flex Fatigue:
Peel strength minimum 30 N/3cm validates interfacial bonding between the patent topcoat and knitted carrier. This is critical-high-gloss topcoats are inherently rigid; poor adhesion leads to delamination at flex points.
Cross-hatch adhesion (ISO 2409): Grade 0 on flat surfaces; Grade 1 permissible on scale apexes.
Wet adhesion: after 24-hour water immersion, peel strength retention ≥85%.
Environmental & Chemical Validation:
Hydrolysis resistance >36 months jungle test; the cross-linked PU network provides additional resistance to moisture ingress versus linear thermoplastic PU.
Phthalate content per REACH Annex XVII: ≤0.01% for 7P (DEHP, DBP, BBP, DINP, DIDP, DNOP, DIBP) via GC-MS.
Formaldehyde below 20 ppm, azo amines below 30 ppm.
Process Controls:
Embossing rolls: chrome-plated, precision-ground, run at 200–220°C at 180 tons pressure. Depth calibrated daily with profilometer.
Carrier knitted fabric monitored for width shrinkage (<2%).
Coating weight monitored via beta-ray gauge; topcoat thickness maintained at 0.15mm ±0.01mm.
Industrial Application Scenarios
Evening & Statement Footwear: Designed for stilettos, pumps, fashion boots, formal men's footwear, and red-carpet shoes requiring reptile aesthetics with mirrored reflectance. The patent finish amplifies scale geometry, delivering dynamic light play across each scale.
Luxury Accessories: Used in high-end handbags, clutches, belt straps, watch bands, cardholders, and wallet exteriors where alligator-scale patent finish signals exclusivity.
Automotive Custom Interiors: Applied in custom dashboard trims, door panel inserts, gear shift boots, and seat upholstery for luxury vehicle personalization. Low-fogging formulation available for automotive-grade orders.
Commercial & Residential Decor: Suitable for feature furniture panels, headboards, decorative screens, and boutique interior wall coverings requiring dramatic visual texture.
FAQ
Q:What embossing depth range is available, and how does depth affect flex life?
Q:Does the patent finish require special handling during high-frequency welding?
Q:The glossy coating tends to stick to itself during roll storage. How should this be handled?
Solamni interleaves release paper between rolled layers for all patent-finish products. For shorter runs (≤100m), we recommend face-in rolling (coating side inward) with core diameter ≥76mm to prevent creasing. Avoid stacking rolls vertically during storage.
