and B Separate

CAUTION

To prevent cross-contamination of the equipment's

wetted parts, never interchange component A (isocy-

anate) and component B (resin) parts.

Foam Resins with 245

fa Blowing Agents

New foam blowing agents will froth at tempera-

tures above 90°F (33°C) when not under pres-

sure, especially if agitated. To reduce frothing,

minimize preheating in a circulation system.

•

When changing materials, flush the equip-

ment multiple times to ensure it is thor-

oughly clean.

•

Always clean the fluid inlet strainers after

flushing, see page 41.

•

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.
