Changing Materials

Changing the material types used in your equipment

requires special attention to avoid equipment damage

and downtime.

• When changing materials, flush the equipment mul-

tiple times to ensure it is thoroughly clean.

• Always clean the fluid inlet strainers after flushing.

• Check with your material manufacturer for chemical

compatibility.

• When changing between epoxies and urethanes or

polyureas, disassemble and clean all fluid compo-

nents and change hoses. Epoxies often have

amines on the B (hardener) side. Polyureas often

have amines on the B (resin) side.
