Dymax adhesives utilise Ultra-Red fluorescing

Many plastics naturally fluoresce blue under UV light; this minimises 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.

This red-fluorescing compound is exclusive to Dymax for use in radiation-cured adhesives and coatings.

When measured, this technology produces a distinct energy peak that cannot be reproduced by any other fluorescing compound, said the company.

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.
