Powders, pearls and flakes for epoxy resin:

The pearl and metallized pigments are incorporated into the epoxy resin to give beautiful iridescent effects, especially for making the famous epoxy river tables, but also marbled epoxy floor resins, for example.

These pearl powders reflect the light and sparkle when added to the epoxy resin.
The particles are light and therefore very concentrated:
5 to 25g are enough to tint 1L of epoxy resin
Being light, they do not fall back and remain in suspension once mixed in the resin.

A myriad of choices of colours and effects to achieve epoxy castings:

(sizes in microns µm) all delivered in 25g pots

- series of 4 basic white pearls (fine or coarse are available)
- series of 16 coloured pearls (commonly used in epoxy river tables)
- series of 8 metallic pearls (metallic shades)
- series of 7 Diamond pearls (extra glitter)

Some pearls are coloured and semi-opaque, while others are transparent and have the appearance of white powders.
These transparent pearls reflect a specific colour when observed under light or on a dark background, and are called "interfering"

Use and mixing of pearls in epoxy resins
Add 25g max per liter of mixed resin and stir. There is no point to stir vigorously, simply disperse the pearls in the resin.
The pearl quantity depends mainly on the thickness of the casting: the lower the thickness, the more one must charge in pearls (up to 5%). On the contrary, for larger thicknesses, it is possible to reduce the pearl content to 0.1% (i.e. 10g/L)

When making a "river table", it is useful to have a dark background if you work with small layer thickness, because the nacres have little opacifying effect, and can be seen through.

Warning ! during the "curing time" or "gel time" of the resin,
nacres can sediment and fall.
To avoid this phenomenon, it is necessary to ensure a fast hardening of the resin:
several solutions exist:
- choose the most suitable type of resin
- and ensure a sufficient thickness, to create a fast hardening
(for 4000 resin: 3 cm, for WWA resin: 10cm)
The phenomenon of pearl deposition is faster with pearls of the Diamond type or flakes.

White pearls (from 5µm to 2mm):
They have the appearance of white powder, and create pure transparent white pearl effects. The smaller the size, the more the white satin effect, and the larger the size, the more gloss the effect.

They are semi transparent and produce a white effect on a white background, and a silver effect on a black background.
The pearl pigments can be tinted with translucent epoxy inks.
Dosage indications 25/L

Coloured pearls (60µm):
Coloured pearl powder, medium size pearls, easy to use and efficient, they are frequently chosen to make the epoxy pourings for "river tables".
They give better results on a dark or black background, except if the thickness of the epoxy casting is 5cm or more
Dosage indications 25/L

Metallic pearls (60µm):
They are pearls that provide a gold or copper aspect, obtained by depositing a thin layer of metallisation on the mica flakes. They are semi-opaque and give beautiful effects when mixed with epoxy resins, especially to make castings in the wood grooves:

Dosage indications: from 5 to 25g/L

Diamond pearls (100µm):
Special pearls made from medium size (100µm) glass micro particles. They are high quality products, with strong reflectory properties: delivered as white pearlescent powder, the Diamond pearls are transparent. In the light, they produce extra iridescent colourful reflections.
They give best results on black or coloured backgrounds. On a white background, they create opalescent reflections.
Dosage indications: from 5 to 25g/L

Holographic pigments (from 20 to 200µm):
Delivered as a grey powder, produced from polyester or aluminum depending on the type and size of the pigments, these effect pigments reflect a full rainbow effect, the colour of which varies according to the position of the observer.
Best results obtained on dark or black backgrounds. Mixture from 5 to 25g/L, in thin or superficial passes (example with 4000 glaze epoxy resin)

Use of pearls or pigments in floor resins:
Stardust® pearls can be used to create beautiful marbled and pearlescent effects in resin floors (whether PU, epoxy or others). They are mixed directly within the mass of the resin, or in a more concentrated portion of resin that is previously applied working in a “net” pattern, before casting the big part of resin. Mixing is possible only in transparent resin.

Pearl pigment composition
Pearls are fine particles in the form of flakes, measuring a few ten thousandths of a millimeter (µm microns).
Initially made with mica, modern pearls have greatly evolved and are now made of different materials, depending on their type and quality, which gives them more purity and iridescence.
Components: Synthetic mica, Silica, Borosilicate, Aluminum, Metal oxides, Polyester
All our pigments are free from toxic substances or heavy metals.

Tinting the pearls with Candy epoxy inks:
To increase the glittering effect, the depth effect and the resin brightness, there is a technique that consists not simply using pearl + resin, but also of adding translucent inks for epoxy resin
These inks are compatible with all resins and are highly transparent: the light passes through, bounces off the pearl, and leaves tinted up to the observer's eye. The quality of the colour visual effect is higher than that obtained with an already coloured pearl, because it is a "light colour".
All types of pearls, especially white, diamond, or metallized, can be used.

Pearls are highly resistant to temperatures and UVs.

S22: Do not breathe dust. The pearl powders are very fine and volatile, they should not be inhaled. Work with air extraction during the mixing. Once mixed, they are no longer dangerous.
