FLUORESCING TECHNOLOGY FOR INSPECTION
Dymax Corp. has introduced Ultra-Red fluorescing adhesives that 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, the company says.
The RoHS compliant technology can also be used by manufacturers for product authentication. The red-fluorescing compound is for use in radiation-cured adhesives and coatings. When measured, the technology produces a distinctly unique energy peak that cannot be reproduced by any other fluorescing compound.
