Changing Materials

• When changing materials, flush the equip-
ment multiple times to ensure it is thor-
oughly clean.
• Always clean the fluid inlet strainers after
flushing.
• Check with your material manufacturer for
chemical compatibility.
• Most materials use ISO on the A side, but
some use ISO on the B side.
• Epoxies often have amines on the B (hard-
ener) side. Polyureas often have amines on
the B (resin) side.
