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 multiple 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 components and change hoses. Epoxies often have amines on the B (hardener) side. Polyureas often have amines on the B (resin) side.
