Technical Details & Test Data
- Post Curing
Satisfactory laminates for many applications can be made from Crystic VE676T by curing at ambient temperature (20°C). For optimum properties laminates should be post cured before being put into service. The laminate should be allowed to cure for 24 hours at 20°C and then be oven cured for a minimum of 3 hours at 80°C; the time will be dependent upon the thickness of the laminate. Post curing at 100°C is advisable for high operating temperatures.
Packaging & Availability
- Packaging Type
- Packaging
- Crystic® VE676T is supplied in 200 kg drums, 1000 kg containers or in bulk by road tanker.
Storage & Handling
- Storage
- Crystic® VE676T should be stored between 5°C and 25°C in the original, unopened container in a dry, well ventilated place. Protect from freezing and direct sunlight. Avoid contact with oxidizing agents. If stored outside of these recommendations, shelf life will be significantly reduced
