PH2329 photoluminescent epoxy paint is a heavy-duty floor coating designed for luminous safety markings.
1.875 kg kit
Solvent-free, odourless and highly wear-resistant, it absorbs light and then emits a green glow in the dark.
Ideal for warehouses, factories, car parks, stairwells and public buildings.
A durable photoluminescent marking system for industrial floors and public access buildings
PH2329 photoluminescent epoxy paint is a new-generation technical coating specially developed to create photoluminescent floor markings capable of withstanding heavy traffic whilst offering exceptional night-time visibility. This professional-grade phosphorescent paint accumulates ambient light energy during daylight hours and subsequently emits a green glow visible in total darkness.
Unlike conventional photoluminescent paints, which are often limited to wall markings, the PH2329 system has been designed for floor applications requiring high mechanical strength, excellent adhesion and high abrasion resistance.
Its 100% solids, solvent-free and odourless epoxy formulation allows for the application of thick coats without shrinkage, evaporation or cracking. The coating also offers excellent resistance to water, hydrocarbons, alcohols, solvents, acids and numerous chemicals found in industrial environments.
Applications and areas of use
PH2329 photoluminescent epoxy paint is designed for creating permanent safety markings in public buildings, industrial sites and areas with heavy footfall.
In particular, it can be used to create:
- Photoluminescent guide lines on the floor
- Evacuation routes
- Luminous markers on staircases
- Safety markings in warehouses
- Warning strips around obstacles
- Markings at the base of walls
- Permanent industrial markings
- Emergency guidance systems in public access buildings
The system is particularly well suited to logistics warehouses, factories and workshops, car parks, plant rooms, industrial buildings, public access buildings, storage areas and logistics hubs
How photoluminescence works
The photoluminescent pigments incorporated into the formulation absorb light energy from the sun, artificial lighting or UV sources. Once plunged into darkness, the coating gradually releases this energy in the form of an intense green afterglow.
The light intensity and afterglow duration depend directly on the applied thickness and the amount of product deposited on the substrate. For optimum performance, the product should be applied over the white P520 primer, which optimises light reflection and enhances the efficiency of the photoluminescence.
The photoluminescence is fully effective in complete darkness. Like all phosphorescent systems, it becomes less visible in the presence of night-time lighting or in dimly lit conditions.
High-performance 3-component epoxy system
The PH2329 kit consists of three pre-measured components:
- Component A: epoxy resin
- Component B: hardener
- Component C: high-performance photoluminescent pigments
The mixture has a solids content of over 99 per cent, with a final density of approximately 1.3 g/cm³. The formulation has low viscosity, allowing application by roller, brush or air spray gun.
The mixing ratio is pre-set to ensure the system’s optimum mechanical and photoluminescent performance.
Mechanical and chemical resistance
The PH2329 system is characterised by:
- Excellent wear resistance
- High surface hardness
- Very good abrasion resistance
- Resistance to common chemicals
- Resistance to water and moisture
- Thermal resistance up to 200°C
- Excellent adhesion to prepared substrates
The maximum glass transition temperature (Tg) of the system is 41 ± 4°C.
Application and usage
The product should be applied to a clean, prepared surface, ideally over P520 white primer. Two coats are recommended to achieve maximum photoluminescent and mechanical performance.
Application methods:
- Epoxy roller
- Brush
- Air-powered spray gun (1.5 to 2.4 mm nozzles)
- The system is not suitable for airless application.
- Recommended consumption:
- Approximately 190 to 235 g/m² per coat
- Two thick coats
- Recommended final thickness: 375 to 420 microns for the entire system
To create a photoluminescent anti-slip coating, glass microspheres with a particle size of 200 to 300 microns can be incorporated into the first coat at a rate of 150 g/m².
Drying times
At 20°C and 60% relative humidity:
- Dust-free: approximately 6 hours
- Handleable: 12 to 16 hours
- Recoatable: 24 hours
- Fully cured: 8 to 10 days
Any heavy use of the coating must be postponed until it is fully cured.
Recommended light recharging
To achieve the best phosphorescence performance:
- Minimum recharging: from 25 lux for approximately 20 minutes
- Optimal recharging: 1,000 to 5,000 lux for a few minutes
- Cool white LED: 5,000 to 6,500 K
- Daylight: 5,500 to 6,500 K
- UV-A: 365 to 395 nm for very rapid recharging
