PLASTIC SCINTILLATOR PAINT

EJ-296

 

EJ-296

 

EJ-296 is a solution of plastic scintillator materials dissolved in a xylene solvent to form a paint for fabricating ultra-thin films or for applying directly to a customer's support surface. Scintillator films as thin as 0.1 micrometer can be made by forming the films on a water surface. Spin casting techniques have also been used successfully to form films of well controlled thickness. EJ-296 is a moderately viscous solution which may be applied as received. For making thinner films, the paint can be thinned with additional solvent.

The fluor system of EJ-296 has been formulated specifically for the fabrication of thin films with two specific considerations in mind: (1) Vacuum compatibility and (2) maximum shifting of the primary scintillation light in thin films. Because the base solvent is xylene, care should be taken in handling and storing EJ-296 with regard to potential flammability. Always work in a well ventilated area.
