Light Interference Pigments/Light Diffractive Pigments
Frequently asked Questions
- What are ColorShift pigments?
- ColorShift is a term that refers to ChromaFlair light interference pigments and SpectraFlair light diffractive pigments. Both were developed based on JDSU's optical thin film technology.
- What is the difference between ChromaFlair and SpectraFlair?
- ChromaFlair light interference pigments change color dramatically when viewed from different angles giving highly saturated and bright colors to coatings, plastic, synthetic leather, etc.
ChromaFlair is a light interference pigment that changes color when viewed from different angles and SpectraFlair is a light diffractive pigment that creates three dimensional prismatic colors. SpectraFlair pigments change from a typical metallic appearance in low illumination, to vivid, multi-rainbow effects in direct bright light.
Both have high pigment flake diameter to thickness ratios which makes the pigments scaled shaped and gives them a high level of specular reflection.
- How many colors are available? Are there color swatches?
- ChromaFlair has seven colors in standard grade. Mixing regular pigments with ChromaFlair pigments can create an infinite number of colors.
SpectraFlair pigments include the Silver 1500 series, which creates a diffractive rainbow effect, and Bright Silver, whose particles look large. The Silver 1500 series comes in three different particle size grades. Color swatches are available upon request. Please feel free to inquire.
- Do you have samples?
- ColorShift pigments are only available for a fee. There are no free samples.
Please note that a contract must be concluded before the purchase of the pigments.
- Are ColorShift pigments weather resistant?
- ColorShift pigments are made from colorless inorganic materials and the colors are produced through light interference effect.
Therefore, the pigments themselves do not fade or change and they are highly UV resistant.
- Are ColorShift pigments used for automobiles?
- Major automobile manufacturers around the world acknowledge the value provided by these pigments and they are adopted for use in a variety of vehicles from sports cars to high-end sedans.
ChromaFlair and SpectraFlair pigments are incorporated in many OEM programs.
ChromaFlair pigments are used for Scion xB, Buick Lucerne, and several Cadillac models. SpectraFlair pigments have been used for vehicles unveiled at the SEMA Show and motor shows in Los Angeles, New York, and Detroit.
- Is it possible to repair coatings that include ColorShift pigments?
- It is possible to repair coatings that include ColorShift pigments in the same manner as you would with other flake pigments using aluminum or mica.
- What is the formulation for ColorShift pigments?
- ColorShift pigments are very easily dispersed and added for use in a wide range of formulations. They can be used with various paints and coatings, synthetic resins, synthetic leather, etc., and the number of original colors you can create by mixing ColorShift pigments with aluminum, carbon black, and other organic or inorganic pigments is limitless.
- What is the property of ColorShift pigments?
- ChromaFlair pigments include 10% solvent (propylene glycol n-propyl ether) and are wet type powders that do not scatter easily.
- What is the appropriate amount of pigment to add in order to achieve the ColorShift effect?
- For general coating formulations we recommend 2-6 percent by weight, but this is not necessarily the ideal ratio when combining other pigments.
- What is the average particle diameter of ColorShift pigments?
- The average particle diameter of ChromaFlair pigments is 20 microns. The SpectraFlair Silver 1500 series are available in three particle sizes: 14, 20, and 35 microns.
