Fluorescing adhesives ease bond inspection
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.
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.
