JFoam™ A-206
JFoam™ A-206 is used in radome fabrication, antenna filling, structural panels, and aircraft control sections. A-206 is not to be used where cross section is greater than three inches. A-206 has a small uniform cell structure and a low viscosity at pour point
Other characteristics
- Brand
- JFoam
- Storage
Avoid moisture contamination during storage, handling, and processing. Store the polyol and isocyanate components from 65°F to 85°F. Do not expose isocyanate component to lower temperatures as freezing may occur
- Shelf LIfe
The shelf life is 12 months if stored in original unopened containers
- Processing Parameters
Blend T component into R component. Mix for about two minutes. Pour at decrease of viscosity and perception of exothermic heat. When foaming action has ceased, postcure immediately. Average cure is about two hours at 200°F. Cool part to 110-130°F before stripping from mold.
