Material Self-ignition
Some materials may become self-igniting if applied to
thickly. Read material manufacturer's warnings and
material MSDS.
Keep Components A and B
Separate
To prevent cross-contamination of the equipment's wet-
ted parts, never interchange component A (isocyanate)
and component B (resin) parts. The gun is shipped with
the A side on the left. The fluid manifold, fluid hous-
ing, side seal assembly, check valve cartridge, and mix
chamber are marked on the A side.
Foam Resins with 245 fa
Blowing Agents
New foam blowing agents will froth at temperatures above
90°F (33 °C) when not under pressure, especially if agitat-
ed. To reduce frothing, minimize preheating in a circulation
system.
CAUTION
Warnings
Changing Materials
•
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.
•
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.
