Crystal NSI
NSI — What Is It
NSI is certified for tough environments and delivers where traditional interlayers compromise.
Know MoreNSI (Nexus Safety Interlayer)
is a high-performance polymer film for architectural, automotive, railing, and smart glass applications. Developed with an exclusive patented formulation, NSI delivers:
- High bonding strength: peel strength up to 6.1 kgf/cm
- Certified UV stability with no yellowing after 3,000+ hours (ANSI Z97.1)
- Excellent resistance to moisture, mildew, salt, and acid
- Superior compatibility with silicone adhesives (0% delam)
- Outstanding optical clarity: haze < 0.5%, luminous transmission ~84%
It's not just another interlayer — it's an evolution of what the market has been asking for.
The Industry's Persistent Challenge
Not every interlayer is made for the demands of modern architecture.
Laminated glass is no longer used just for aesthetic enhancement — it's now a critical structural and safety component. Whether applied in high-rise facades, exposed-edge balconies, curved panels, or smart glass units, laminated glass must meet three non-negotiable demands:
Bond strength that maintains structural integrity after breakage
Visual clarity that lasts through time, heat, and UV
Resistance to environmental factors like humidity, silicone, salt spray, and acidic exposure
Professionals are forced to choose between compliance and cost — until now.

NSI Has Been Tested — and Proven Against Every Failure Scenario
Peel Strength
6.1 kgf/cm — significantly higher than PVB/EVA
Moisture Resistance
0% delamination after 6-month salt & acid test
Silicone Compatibility
Passed 5-month oven test at 60°C — 0 bubbles
UV Stability
No yellowing/haze after 3,000h UV (ANSI Z97.1)
Transparency
Luminous transmission >84%, haze <0.5%
Exposed, Frameless Glass — No Edge Seal Needed.
Structural performance with exposed edges — engineered to hold clarity and bond without edge sealing.
From sky decks to infinity-pool railings, glass systems today are frameless and minimal — but exposed to harsh elements.
NSI solves a global challenge:
- No delamination or fogging even without edge sealing
- Maintains structural integrity after impact
- Certified safe for silicone-glazed systems (tested with Dowsil, Sika, GE silicones)
- Holds load and bond strength after breakage, even on 19mm annealed glass
Railing may be the toughest test for any interlayer — and NSI passes with confidence
Applications Beyond Railing
- High-rise building facades
- Curved glass (radius ≥ 40mm)
- Shower screens and bathroom glass
- Automotive windshields and side windows
- PDLC and switchable glass lamination
- Transparent structures and partitions
