Radiant Optical Brighteners are highly fluorescent under UV light (black light), so you can better monitor fluid movement and identify leaks in systems or containers before it's too late. In addition to being a highly effective leak detection dye, they’re used widely in product identification applications.

Supplied in dry form and with excellent solubility and thermal stability, our tracer dyes excel when used in non-destructive metal testing to spot any imperfections, cracks, or damage. In addition to their use as a flow analysis dye, Radiant Optical Brighteners are also widely used in a host of adhesive applications.
