EJ-290 is a partially-polymerized plastic scintillator formulated for final curing in the user's facilities at a relatively low temperature. It is supplied in a kit form consisting primarily of the scintillator resin and a polymerization initiator. Upon combining the ingredients in accordance with the provided instructions, a solid plastic scintillator can be made at a relatively low polymerization temperature. The final scintillation and physical properties are quite similar to those of the conventional blue-emitting plastic scintillator EJ-212.
