EJ-520 is a bright white paint consisting of titanium dioxide
pigment and a paint base selected for its inertness to the solvent
action of nearly all liquid scintillators.
Unlike other paints based on epoxies, EJ-520 does not develop
a yellow cast as it ages.&nbs;
The paint base is a two-part polyurethane selected for these
It is intended for coating the inside walles of metal cells
intended for holding liquid scintillators including those based
on xylene and toluene which exhibit strong chemical solvent
Liquid EJ-520 contains strong solvents which can attack many
plastics and hence should not be used on plastic scintillators
or on liquid scintillator cells fabricated out of plastics
materials such as acrylics.
Use EJ-510 Reflective Paint for these latter applications.
