Message to our customers as we continue to monitor COVID-19 we want to keep you informed on how Dymax is handling this unprecedented situation.
Dymax light-curable materials remain clear until exposure to UV light at which point they cure and fluoresce bright red.
Dymax light-curable adhesives and coatings remain clear until exposed to UV light. When materials with Ultra-Red fluorescing technology are exposed to UV light, they fluoresce bright red. The bright red fluorescence contrasts extremely well on solder masks, components, and plastics that naturally fluoresce blue in color (like PVC), greatly assisting with visual inspection of the bond-line or coated area.
Ultra-Red fluorescence does not absorb the same light energy wavelengths as those used to cure the adhesives and coatings, resulting in faster, deeper cures. Additionally, adhesives and coatings containing Ultra-Red fluorescence are not as yellow in appearance.
The patented Ultra-Red fluorescing compound is exclusive to Dymax for use in radiation cured adhesives and coatings. When measured, this compound produces a unique energy peak that cannot be reproduced by other fluorescing compounds. This technology offers manufacturers the ability to assemble or mark their products so they can be positively identified.
Ultra-Red fluorescing technology can be formulated into new or existing Dymax products.
