Important Two-Component Material Information

Changing Materials

•Changing material types used in your system requires special attention to avoid equipment dam- age and downtime.

•Always clean the fluid inlet strainers after flushing.

•When changing between epoxies and urethanes or polyureas, disassemble and clean all fluid compo- nents and changes hose sets.

•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 (hardener) side. Polyureas often have amines on the B (resin) side.

A and B Component Designations

Material suppliers and markets refer to plural component materials differently. The table below summarizes the differ- ent designations for the components used in various machines.
