ADA sign fabricators have been working around a gap for years. When signs go outdoors, on building facades, in parking garages, near pools, or inside cold storage facilities, most photopolymer substrates simply weren’t built for it. They yellow. They bubble. The layers separate. Fabricators have had to make do with materials designed for interior conditions and hope for the best.
Nova Polymers has closed that gap.
We have officially launched the Novacryl® EX™ Series, now new and improved, and it’s the first product the ADA sign-making industry can honestly call a pure exterior-grade photopolymer. Not exterior-adjacent, not “suitable for some outdoor use”, just “purpose-engineered for the conditions that used to shorten a sign’s life and compromise its compliance.”
What Is the Novacryl EX Series?
The Novacryl EX Series is a photopolymer substrate specifically formulated for high-moisture and high-humidity environments. It’s built on a base of .017″ aluminum bonded to a .032″ extruded photosensitive synthetic rubber compound, with a two-year shelf life.
What makes it different isn’t just the material spec, it’s the design intent. Tim Lloyd, Director of Business at Nova Polymers, described it plainly at launch: “This substrate is specifically engineered for uncompromised durability in extreme heat, cold, moisture, or sunlight. This innovation addresses critical challenges faced by sign manufacturers, providing a true and tested solution that maintains structural integrity and aesthetic quality under the most demanding outdoor and indoor conditions.”
The Novacryl EX Series produces crisp, compliant Braille, raised characters, and pictograms; the details that make ADA signs legally functional, not just decorative. If those elements degrade, the sign fails its purpose. The EX substrate is formulated so they don’t.
The Problem with Other Substrates Outdoors
Here’s what actually happens when a standard photopolymer substrate gets installed in an outdoor or harsh indoor environment: UV exposure causes yellowing and fading, heat cycling causes the layers to expand and contract at different rates, and moisture works its way into any weakness in the bond. The result is bubbling, peeling, or full delamination.
That’s not a worst-case scenario. For most interior-grade substrates, it’s a matter of time.
The Novacryl EX Series was developed to address each of those failure modes directly. No bubbles, no peeling, no delamination, and those aren’t marketing claims; they’re the structural outcomes of a formulation designed from the ground up for exterior use. Where other substrates yellow or fade under prolonged sun exposure, the EX Series holds its color and integrity.
For fabricators, that means fewer callbacks, fewer replacements, and less risk of putting a client in a compliance situation down the road.
Why Exterior-Grade Photopolymer Matters for Outdoor ADA Signs
Outdoor ADA compliance isn’t optional, and it doesn’t come with a grace period for material degradation. A sign that has faded to the point where contrast is compromised, or where Braille cells have separated from the substrate, is non-compliant, full stop.
Exterior-grade photopolymer solves this in a way that other material approaches don’t. Some fabricators have turned to metal or acrylic alternatives for outdoor applications, but those come with their own trade-offs in processing, cost, or the quality of the tactile elements they can produce. Photopolymer, when it’s genuinely formulated for outdoor conditions, gives fabricators the same reliable production process they already know, with output that can actually stand up to the environment.
The EX Series processes the same way Novacryl’s interior substrates do. No extended treatments, no tacky or gummy polymer layer to deal with, no new workflow to learn. Fabricators get the exterior performance without the learning curve.
That compatibility extends to finishing as well. The EX Series works with all exterior paints without requiring additional surface treatments, which keeps the finishing process clean and consistent.
Where the Novacryl EX Series Is Built to Perform
The range of applications Nova Polymers lists for the EX Series is telling.
This isn’t a product aimed at a narrow use case:
Building Exteriors — Permanent outdoor signage on facades, entrances, and wayfinding paths where UV exposure is constant, and weather varies by season.
Parking Garages and Stairwells — Environments with temperature extremes, exhaust exposure, and moisture from rain or snow infiltration.
Loading Docks — High-traffic areas with variable temperature, humidity, and physical wear.
Indoor Pools and Waterparks — Among the most punishing environments for any substrate. Chlorine, humidity, and condensation create conditions that will eventually destroy materials not built for them.
Gym Locker Rooms, Spas, and Saunas — Persistent heat and moisture exposure that standard materials simply weren’t designed to handle.
Cold Storage Facilities — Extreme cold combined with moisture creates a unique failure risk for layered substrates. The EX formulation holds under these conditions, where others crack or separate.
If you’re specifying or fabricating signs for any of these environments, the EX Series is the substrate that actually belongs there.
