BC-634A is a silicone-adhesive coupling compound for making an optically clear bond between the scintillator and photomultiplier tube. BC-634A is formulated for use within the temperature range of -10 to +60oC, has an index of refraction of 1.42 and an internal transmission >98% around 400nm. BC-634A is a self-wetting, flexible pad just hard enough to resist tearing while handling.
Note: If you cannot maintain sufficient interface pressure, apply a thin film of coupling grease to both sides of the interface pad.
BC-637 interface pads are a silicone-adhesive coupling compound for making an optically clear bond between the scintillator and photomultiplier tube. BC-637 is rated to 200oC.
We supply as ready-to-use disks in specified diameters and in thicknesses of 1, 3 and 6 mm.

BC-638 is a black adhesive tape 2" (50.8mm) wide by .008" (0.2mm) thick. Wrapping a plastic scintillator in one layer will give you a light-tight seal.
Size: 2" wide X 32.9m long Ordering Part number: S-1033-1
BC-640 is an adhesive-backed masking paper routinely used for protecting the surfaces of plastic scintillators during handling or storage.
Size: 12” (30.5cm) wide by 300' (91.4m) Ordering Part number: 6640-00002
BC-642 Teflon® tape is frequently used as a reflecting material for non-hygroscopic scintillators. Three layers give you optimum reflectivity.
2" wide X 13.7m long on 3" PTFE core .003" (0.08 mm) thick (normal) Ordering Part number: S-1006-7
