Technical Details & Test Data
- Processing Parameters
Process Polyol 3020B at 100 to 150 degrees F.
Melt Isocyanate 680A if frozen at 100 degrees F., otherwise use at 75-120 degrees F.
Mold Temperature: 65 to 110 degrees F.
Mix ratio: 1 part Polyol 3020B to 1 part Isocyanate 680A by volume or 91.20 parts polyol to 100 parts Isocyanate 680B by weight.
Degas mixture if possible or pre-degas Polyol in dispensing equipment prior to casting.
Demold 10-15 minutes with maximum process and mold temperature. Catalyst may also be used to shorten demold time.
Post Cure: 16-24 hours @ 75 degrees F.
Storage & Handling
- Storage and Pot Life
Systems should be stored unopened in air tight containers at 60-90 degrees F. Partially emptied containers should be swept free of atmospheric moisture with dry nitrogen before sealing.
Pot life: (200g mass) (100 degrees F) 10 to 15 minutes.
