Ultra-Red™ adhesive aids inspection and authentication

Published on 2009-10-08. Author : SpecialChem

Intertronics, the clever adhesives people in Oxford, are persuading their customers to "see red" literally. The Ultra-Red™ fluorescing technology built into many DYMAX adhesives offers assemblers concrete advantages in plastics fabrication.

Fluorescing adhesives from Intertronics

Many plastics naturally fluoresce blue under UV light - this minimizes the inspection advantages of using blue-fluorescing adhesives in parts assembly. Ultra-Red™ fluorescing adhesives remain naturally clear until exposed to UV light, at which point they fluoresce bright red providing a vivid contrast that permits accurate bond-line inspection. The red fluorescence does not absorb the same light energy wavelengths as those used to cure the adhesive, resulting in faster and deeper cures when compared with the same adhesives containing blue fluorescence.

Ultra-Red™ fluorescing technology can also be used by manufacturers for product authentication. By virtue of its patented technology, the red-fluorescing compound is exclusive to DYMAX for use in radiation-cured adhesives and coatings. When measured, this technology produces a distinctly unique energy peak that cannot be reproduced by any other fluorescing compound.

This offers manufacturers the ability to assemble or mark their products and be assured that, in the event of a future challenge as to the authenticity of the product's origins, the products can be positively identified. Ultra-Red™ fluorescing technology is RoHS compliant.
