Front Panel Frame
The front panel frame for all the 4612’s and 4615’s is made of powder-coated
aluminum. The key ingredients are pure polyester, TEPIC-G, titanium oxide,
barium sulfate, leveling agent, and carbon black. Material that may come in
contact with the 4615 unit should be carefully evaluated under end-use conditions
for compatibility. See Table 4-1 and Table 4-3 for a list of compatible chemicals.
Chemicals Compatible with 4612T Frame
Table 4-1 should be used only as a guide. Specific testing should be conducted to
verify that the unit’s finish would meet the demands of extreme environments.
