T-6134NS is a high-performance, 100% solids UV-curable resin engineered for demanding optical coating applications. By chemically coupling multifunctional acrylates with specially designed hollow‑structure silica nanoparticles, it achieves an exceptionally low refractive index (1.345) while maintaining outstanding transparency, minimal haze, and excellent mechanical properties – all without fluorine.
Key Features
| Feature | Benefit |
|---|---|
| Ultra‑low RI (nD²⁵ = 1.345) | Enables high‑performance anti‑reflective (AR) and high‑transmission coatings without fluorinated components. |
| Fluorine‑free formulation | Environmentally friendlier, more cost‑effective, and avoids compatibility/separation issues associated with fluorinated materials. |
| Hollow silica nanotechnology | 50 nm particles, 50–60 wt% loading – lowers refractive index via trapped air (n≈1.0) while keeping haze <1%. |
| High hardness & scratch resistance | Multifunctional acrylate backbone provides high crosslinking density and excellent abrasion resistance. |
| Good processability | Viscosity 2000–3000 mPa·s at 25 °C – suitable for spray, roll, slot‑die, and gravure coating. |
| Fast UV curing | High reactivity enables high line speeds and energy efficiency. |
| 100% active content | Solvent‑free, low VOC, and environmentally responsible. |

Applications
T‑6134NS is designed for use in high‑precision optical and display films:
Anti‑reflective (AR) coatings – Single or multi‑layer structures on glass, PET, TAC, and other optical films.
High‑transmission coatings – Boosts light transmittance for displays, cover lenses, and solar panels.
Nano‑coatings for optical films – Imparts low RI, abrasion resistance, and clarity.
Fiber optic cladding – As a low‑index buffer or cladding layer.
Adhesive applications – Limited to optical bonding where low shrinkage stress is acceptable (see formulation tips below).
Formulation & Handling Tips
Critical recommendation: Because T‑6134NS is highly crosslinked and contains high inorganic content, it tends to exhibit high shrinkage, high internal stress, and brittleness. For best results, always blend with low‑functionality acrylates to improve toughness, flexibility, and adhesion.
Suggested formulation approach
| Component | Function | Example (weight parts) |
|---|---|---|
| T‑6134NS | Low‑RI base, hardness | 60 – 80 |
| Low‑functionality acrylate resin (di‑ or monofunctional, e.g. urethane acrylate) | Reduce shrinkage, improve flexibility & adhesion | 20 – 40 |
| Photoinitiator (e.g. TPO, 184) | UV curing | 1 – 3 (depending on lamp & film thickness) |
| Reactive diluent (if needed, low‑RI type, e.g. IBOA, LMA) | Viscosity adjustment | 0 – 10 |
Coating & curing conditions
Apply by slot‑die, roller, or spray coating.
Cure under medium‑pressure mercury lamp or LED (365/395 nm).
Typical film thickness: 0.5 – 5 µm (for AR applications).
Post‑cure annealing (60 °C for 10 min) may further relieve stress.
Substrate compatibility
Excellent on glass, PET, PC, PMMA when properly primed or blended with adhesion‑promoting resins.
For polyolefin films (e.g., PP, PE), a primer or higher‑content adhesion resin is recommended.
Handling & Storage
Store in original, opaque container at 5 – 35 °C, away from direct light and heat.
Avoid prolonged exposure to UV or daylight.
Shelf life: 12 months from date of manufacture when stored properly.
