ULTRAGLOW Blue is a high-intensity photoluminescent powder filler for direct incorporation into epoxy, polyurethane, polyester and acrylic resins. Its luminous output surpasses other fillers on the market by up to 10 times, with a powerful and long-lasting blue emission. It is the go-to option when luminescence is the star of the piece.

What it is used for
ULTRAGLOW Blue is mixed with the resin before casting to create pieces that glow in the dark with great intensity and duration. It absorbs ambient or artificial light and re-emits it in blue for hours. Its versatility makes it suitable for both decorative and functional applications.
- Cosplay pieces with nocturnal luminous effects
- Jewellery and costume jewellery with transparent epoxy resin castings
- Space decoration and theming (Halloween, special settings)
- Decorative elements for aquariums and terrariums
- Hobby and craft resin projects
- Emergency signage and photoluminescent signalling
- Luminous inlays and details in countertops and composite pieces
- Art and sculpture with special effects
How to use it
- Prepare your resin following the manufacturer's instructions. Mix component A (resin) with component B (catalyst or hardener) in the indicated proportions.
- Add ULTRAGLOW Blue to the already prepared resin mixture. Start with an approximate proportion of 10–20% by weight of the total resin and adjust according to the desired glow intensity. There is no strict upper limit: the higher the proportion, the greater the luminous intensity.
- Stir slowly and evenly to disperse the powder without introducing bubbles. Avoid excessive or vigorous mixing.
- Pour into the mould or apply to the surface. If the resin allows it, work in thin layers to improve the homogeneity of the dispersion.
- Allow to cure according to the times indicated for the chosen resin. Do not apply heat to accelerate curing if the resin does not require it.
- Once the piece has cured, expose it to light (solar or artificial) for a few minutes to charge the photoluminescent material and check the effect in the dark.
Usage tips
Filler proportion and transparency
With transparent resins such as epoxy, a low proportion (5–10%) maintains a certain translucency in the piece with a good luminous effect. Increasing the amount gives greater glow intensity but the piece loses transparency. Test on a small scale before undertaking the final casting.
Particle size and sedimentation
Photoluminescent powder tends to settle in low-viscosity resins during curing. To prevent this, use a resin with a short gel time or add a thixotropic agent such as Gel de Sílice AT2 to increase viscosity and keep the powder in homogeneous suspension until the resin gels.
Charging and recharging the luminous effect
Photoluminescent performance depends directly on the quantity and quality of light absorbed. UV light or direct sunlight charges the material faster and with greater intensity than conventional artificial light. The more intense and prolonged the exposure to light, the greater the duration and intensity of the glow in the dark.
Frequently asked questions
Which resins can I use a photoluminescent filler in?
ULTRAGLOW Blue is compatible with epoxy, liquid polyurethane, polyurethane foams, polyester and acrylic resins. The key is that the resin has low viscosity or that the filler proportion is adjusted to ensure good dispersion before curing.
How much filler should I add to the resin?
A common starting proportion is between 10 and 20% by weight of the total resin. You can adjust the amount according to the glow intensity you need: more filler equals more glow, although beyond a certain point the improvement is marginal and the piece loses transparency. It is always advisable to do a small-format test first.
Does the photoluminescent powder affect the curing of the resin?
In general, inert powder fillers such as ULTRAGLOW Blue do not interfere with the curing reaction of epoxy, polyurethane or polyester resins. However, very high proportions may slightly slow down the process or modify the exotherm. Always respect the mixing proportions indicated for the base resin and run a test before production.
How do I prevent the powder from settling at the bottom of the mould?
Sedimentation is the main challenge with powder fillers in fluid resins. You can minimise it by using resins with a short working time, adding a small amount of Gel de Sílice AT2 to increase viscosity, or pouring in alternating layers of pure resin and resin with filler.
How long does the material glow once charged?
The duration of the glow depends on the time and intensity of prior exposure to light. With adequate charging under sunlight or UV light, ULTRAGLOW Blue can emit visible light for several hours in conditions of total darkness. The emission gradually decreases over time.
Is it compatible with coloured or pigmented resins?
Technically yes, but opaque or heavily saturated pigments mask the luminous emission. To make the most of ULTRAGLOW Blue's effect, the ideal is to use it in transparent or very lightly pigmented resins. If you need daytime colour and nighttime glow, consider using the powder in a top or inner layer protected by a transparent layer.
Can I use photoluminescent fillers of different colours in the same piece?
Yes. You can combine ULTRAGLOW Blue with ULTRAGLOW Verde in different layers or areas of the piece to create multicolour effects in the dark. Mixing them directly in the same layer will produce an intermediate emission colour.
Are there any safety risks when using this powder?
Like any fine powder, it is recommended to work with a particle mask to avoid inhalation during handling. Once encapsulated in the cured resin, the material is inert and harmless. Consult the safety data sheet available on the product page at Feroca.
