Interference Pearlescent Pigments

  • Pigments that create translucent, pearl and subtle colour effects.
  • For resin, arts & crafts and industrial applications.
  • Heat, pH and chemical resistant. Non-fading.

Interference Pearlescent Pigments

All these pigments have a high degree of light fastness (non-fading) and excellent tolerance to a wide temperature and pH range. They also have good chemical resistance. We have selected these pigments specifically because they have these properties so they are perfect for almost all arts and craft applications (including all resin types) as well as for industrial applications

Fine Size Pigments

The pigments with fine particle size can be used to achieve unique effects when added to clear resins. 

  • When used with very low addition levels these pigments give translucent effects with subtle colour generation.
  • When used with very low addition levels in resins that are applied over a black background then strong pearl colour effects result. In order to achieve the strong pearl colour effect the addition rate must be extremely low and it is essential to apply the resin over a black resin layer or over black acrylic paint. 
  • At higher addition levels a solid cream pearl colour results but curved surfaces show beautiful hints of subtle colour. 

Medium and Large Size Pigments

  • As particle size increases, the effect becomes more of a sparkle effect and less of a continuous colour effect. Larger particles create more or a translucent effect with subtle sparkle. 
  • A downside of larger particles is that they have more tendency to settle in high flow (low viscosity) resins during curing. To counter this they can be used in a thin top resin layer or into a thin layer of higher viscosity resin such as our Counter Top resin. 

Interference Pearlescent Pigments vs. Colour Pearlescent Pigments

All pearlescent pigments get their colour and other visible effects by reflecting and refracting light. Reflection is light bouncing off the particle surface while refraction is light passing through the particle and being changed as it does so. Light that passes through the particles changes wavelength and thus colour.

In our “Colour Pearlescent Pigments” all the pigments have quite a strong colour and are not very transparent. They generate beautiful metallic colour effects primarily by reflection of light. 

In our “Interference Pearlescent Pigments” all the pigments have a subtle colour with a high level of transparency. They tend to "play with light" and generate colour through refraction. They don’t contain any coloured material in their composition but manipulate light to give the perception of colour. A pile of powder of these pigments looks white but smearing these pigments out over a glossy black surface readily demonstrates the awesome effect they can create.

Mica, Synthetic Mica and Glass

Pearlescent pigments are created on a transparent base material. Mica naturally has platy shaped transparent particles and has been the traditional base used during the manufacture of pearlescent pigments. Synthetic man-made mica has been replacing natural mica in many pearlescent pigments as it is more transparent and has a more uniform particle size. Synthetic mica is, however, more expensive. Glass is regarded as the ultimate base for pearlescent pigments as it is even more transparent than synthetic mica. 

As particle size increases it become more essential for particles to have a transparent base. For this reason our fine interference pigments are based on natural mica, our medium pigments are based on synthetic mica and our large pigments are based on glass. This is a major reasons why the larger particle size pigments are significantly more expensive. Fortunately with the larger particle sizes only a very small amount is required to create a sparkle effect which is why we only sell them in 10g units. For the absolute ultimate sparkle effect please see a different product called "Cosmetic Diamond Pearlescent Pigments". 

Potential for dust generation

Care should be taken not to breathe the dust of any pigment powders (careful handling will reduce dust generation). Use a fabric dust mask that you can buy at any hardware store. If handling larger quantities (more than normal arts and crafts requirements) then a dust extraction system is required. 
Keep out of reach of children
All our products should be kept out of reach of children under 5 years and anybody who may tend to place items or liquids in their mouths should be supervised. Even packing can become a choking hazard.
