Description
FLX™ Opus UV Ink Series – Flexible, Durable, Outdoor-Grade Screen Inks
SunChemical’s FLX™ Opus Series is a premium single-package, UV-curable ink system designed for demanding exterior applications. Formulated without NVP, FLX offers high elongation and flexibility—perfect for printing on premium pressure-sensitive PVC films used in outdoor graphics, vehicle wraps, and signage.
It’s engineered to resist edge curl, cracking, and fading in challenging conditions, including riveted and corrugated surfaces.
The FLX series is rated for 3 to 5 years of outdoor durability (Zone 1) when used in conjunction with the recommended FLX-C501 Super Overprint Clear and printed to specification. It performs reliably in accelerated weathering tests and offers superior adhesion, even on difficult substrates like rigid PVC, polycarbonate, and top-coated polyester—though adhesion and flexibility should always be pre-tested on non-PVC surfaces.
Key Benefits:
- UV-curable & NVP-Free for safer press operation
- High elongation & flexibility for complex application surfaces
- Edge-curl resistant, ideal for pressure-sensitive vinyl applications
- Rated up to 5 years of exterior durability (Zone 1) with proper overprint
- Vibrant color options including SWOP process and mono-pigmented blending shades
- Excellent adhesion on PVC and tested compatibility with polycarbonate and polyester
- Easy to handle single-package system, modifiable with ST-350 Viscosity Modifier or ST-370 Cure Accelerator
Applications:
- Long-life outdoor graphics
- Vehicle wraps and decals
- Corrugated and riveted surfaces
- Pressure-sensitive vinyl signage
Curing & Handling:
FLX inks cure under UV exposure at 250–500 mJ/cm² depending on deposit and color. Proper mesh selection (305–420/inch) and a sharp 75–85 durometer squeegee are recommended for best results.
Recommended Emulsions:
For best stencil durability and resolution with UV inks, we recommend the following emulsions:
- Murakami SR
- Chromaline UDC ACE
- Saati SAATIGRAF HS3
- Saati Grafic HU
These can be found in our Solvent & UV Emulsions collection.
Durability Zones:
- Zone 1: Up to 5 years
- Zone 2: Up to 4 years
- Zone 3: Up to 3 years
(Refer to SunChemical’s FLX Weathering Statement for full zone breakdowns.)
For demanding exterior signage where flexibility, adhesion, and weather resistance are critical, the FLX Opus series delivers high-end results with industry-proven reliability.
