NIR Absorbing Coatings

Epolin offers Spectre™ solvent screen inks for near infrared (NIR) absorbing applications. These applications include security printing, laser blocking, machine vision, bar codes and other digital electronic devices.

When printed, Spectre coatings are visibly transparent and absorb discrete NIR wavelengths. Spectre screen inks can be printed on PET, polycarbonate and PVC substrates. By request Spectre inks can be formulated for better adhesion to glass.

Spectre inks are designed for the screen printing process. Epolin can recommend the addition of solvents which will enable the ink to be sprayed.
