Epolin’s headquarters and manufacturing are in Newark, NJ USA. Epolin products ship around the world and have been used in over 45 countries.
Epolin has been in business since 1984 providing UV, Visible, and NIR Dyes for Light Management, Eye Protection, and other applications.
Product Information
Epolin offers a diverse range of UV, Visible, and NIR absorbing dyes, Ready to Mold thermoplastic Pellets, Inks, and film solutions.
The easiest way to think about dyes and pigments is to think of pigments like sand in water. It is a physical particle that you can stir up, but it will always remain as a grain of sand. Dyes behave more like Sugar in water. The Dye will dissolve down to the molecular level and become part of the solution.
Different dyes have different solubility levels. Thinking back to sugar and water, there becomes a point where the water has absorbed so much sugar that it can’t absorb any more. At that point the sugar will pile up at the bottom. Dyes behave in a similar fashion. The dyes will dissolve into the solvent or thermoplastic to a point. After that point of saturation, they will start to behave like a pigment that no longer dissolves.

Epolin dyes will dissolve down to the molecular level, so particle sizes are not a concern like they are with Pigments
Epolin has dyes that absorb from 200nm in the Ultraviolet range out to ~3000nm in the Infrared.
Epolin dyes are soluble in Amorphous thermoplastics. Crystalline or semi-Crystalline plastics will often cause the dyes to migrate.
Epolin traditionally puts dyes into Solvent Coatings, Polycarbonate, or PMMA. We recommend testing the dyes in your application or particular substrate or solution.
Epolin typically certifies our dyes for 2 years. At that point Epolin could retest and recertify a small sample from your inventory.
VLT typically refers to Visible Light transmission. This is the measurement of the amount of light transmitting in the visible spectrum from approximately 380-780nm This is measured with a Spectrophotometer.
Optical Density refers to the attenuation of light or energy through the dyes. The higher the OD value the more the energy will be reduced. You can use Epolin’s Absorbance Calculator to convert absorbance and transmittance.
Epolight is the brand name for Epolin’s dyes and dye formulations.
Luminate is the brand name for Epolin’s ready to mold thermoplastic pellet.

–Epolin does not provide free samples, but we do offer product quotes down to 1 gram for ease of testing.
–Absolutely! Epolin specializes in tailoring dye formulations to suit your unique requirements. To discuss your specific needs, please reach out to our sales team to discuss your Custom Formulation requirement. Epolin can computer model a solution and show you expected results prior to any initial production.
–Advice for those requesting a dye from Epolin, here are the key details you should include:
– Please specify the solvent you intend to use, as this can impact the dye’s compatibility and solubility.
– If the solution is using a thermoplastic, please provide the thickness of the part at the eye or sensor center.
–Specify if you need the dye to absorb multiple wavelengths or if you have specific absorption peaks.
–If there are Optical Density or Transmission targets, please let us know
–Share any stability requirements, such as resistance to heat, light, or other environmental factors, that the dye should meet.

–Epolin can help to provide recommendations on dye loading.
–Generally, we need to know the thickness of the part or the coating
–Any optical density or transmission targets
–The dyes are very strong and only a small amount of dye is needed to hit most optical targets.
–Epolin dyes can be fragile in some situations. Typically, there are concerns about using them in situations where they will be exposed to sunlight. Chemical exposure to strong acids or bases can also cause the dyes to degrade. Finally, excessively high temperatures can cause dye degradation.
–Typically, degradation of the dye will result in the dye molecule breaking down. Often this will result in the dye absorbing in the visible portion of the spectrum which can be seen as a dark brown or black color. Measuring the dye will show that its absorbance no longer matches that on the datasheet.
–Epolin has a wide range of analytical capabilities, and we are happy to help you ensure the dye is performing to specification in your application. Often sending Epolin a sample of the finished part with the dye will allow us to measure and compare the performance of the dye to its original analysis.
