Important Two-Component Material Information

•Use moisture-proof hoses specifically designed for ISO, such as those supplied with your system.

•Never use reclaimed solvents, which may contain moisture. Always keep solvent con- tainers closed when not in use.

•Never use solvent on one side if it has been contaminated from the other side.

•Always lubricate threaded parts with ISO pump oil or grease when reassembling.

Foam Resins with 245 fa Blowing Agents

Some foam blowing agents will froth at tem- peratures above 90°F (33°C) when not under pressure, especially if agitated. To reduce frothing, minimize preheating in a circulation system.

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.
