Important Isocyanate Information
Foam Resins with 245 fa Blowing

above 90°F (33°C) when not under pressure,
especially if agitated. To reduce frothing, minimize
preheating in a circulation system.
Changing Materials
NOTICE
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.
