- 125°C (257°F) Cure
- Expanding Syntactic Core
Features & Benefits
- Materials Features
- Product Highlights
- Density/strength may be tailored by simply changing cure pressure or limiting volume available for expansion.
- Capable of expanding up to 650%**
- Forms a closed cell structure
- Capable of generating internal pressure during cure
- Compatible for co-cure with Toray’s E720 and E722 prepreg
- 30 days out life at ambient temperature ** Variations in heat-up rate, cure temperature, pressure and thickness are all factors that influence the expansion (e.g., at 1-mm thickness an expansion of 250% can be achieved. Increasing the thickness will increase the expansion).

Remove from cold storage and allow to reach room temperature before removing from polythene bag. Trim to required shape and remove release paper from one side. Place in position and remove remaining release paper.
Caution: ES72A-2 syntactic core contains a reactive resin system and care must be taken to avoid exothermic heating during the cure.

Technical Details & Test Data
- Recommended Cure Cycle
- Increase air temperature at 2.5°C (4.5°F)/min to 125°C (257°F) and hold for 1 hour
- Allow to cool to 60°C (140°F) prior to releasing vacuum and removal from mold
Safety & Health
- Product Safety And Shelf Life
Handling Safety:
This product may cause skin irritation. Avoid skin contact. If contact occurs, wash with soap and water at the first opportunity.
SHELF LIFE:
- Out Life : 30 days at 20°C (68°F)
