Water Soluble Absorbing Dyes

UV, Visible and NIR Dyes for Aqueous Systems

QCR Solutions’ Water Soluble NIR Dyes and Water Soluble Absorbing Dyes are available in a wide spectral range. We have a large library of standard Water Soluble absorbing dyes ranging from narrow notch to broad band absorbers that can attenuate selective wavelength regions. These Water Soluble Dyes can be used singly or in combinations to create custom spectral filters for multiple applications.

Our Water Soluble NIR Dyes and Water Soluble Absorbing Dyes can be incorporated into aqueous coatings, inks, and solutions. These Water Soluble Absorbing Dyes can be used for Laser Protection Eyewear, Light Filters (narrow or broad band), Welding Protective Eyewear, Security Inks, Graphics and many more applications.

Below is a representative list of our Water Soluble Absorbing Dyes. Also available is our helpful guide on how to calculate your absorbing dye’s starting concentration: Concentration Calculation Worksheet | 2018 | QCR Solutions Corp

If you can not find the right absorbing dye from the above list. Just let us know your application’s specification and we will custom synthesize the perfect absorbing dye (UV, Visible, or NIR) for your project:

Wavelength required to be absorbed, filtered, or blocked
Wavelength required for high transparency
Matrix Compatibility (Solvent, Plastic, or other)
Process Conditions
Lightfastness
Thermal Stability

Let us design an absorbing dye for your next NIR light filter, Security Coating or other application. We look forward to working with you.
