One Component, Moderate Viscosity, UV Curable System

Master Bond® UV24TKLO is a one part UV curable epoxy modified formulation for bonding, sealing and encapsulation. It passes the rigorous requirements for low Outgassing as per ASTM E-595. Most noteworthy, it has outstanding resistance to chemicals, as described in part below. UV24TKLO has excellent clarity and optical transmission properties. The best wavelengths for curing are 320-365 nm and the energy requirement is 10-40 milliwatts per cm². This epoxy system is not oxygen inhibited.

UV24TKLO has superb physical strength and electrical insulation properties. The service temperature range is -60ºF to +400ºF. The UV24TKLO can be cured in thicker sections, up to 1/16 of an inch and can be easily “layered” to higher levels. The low outgassing properties enable this UV to be used in a wide array of optical, electro-optical and vacuum applications that until now have not been possible for UV curable systems. It should be noted that to optimize the outgassing properties, the UV24TKLO should be preheated to approximately 50ºC for 15 minutes prior to use and then allowed to cool down to room temperature.
