Applications & Uses
- Markets
- Composites Processing Methods
- Recommended Applications
Crystic VE671-03 was designed for use in closed mold applications and centrifugal casting processes. It is recommended for the manufacture of fiber reinforced composite tanks, vessels, ducts etc. for use in chemical processing applications.
- Formulation Guidelines
Crystic VE 671-03 should be allowed to attain workshop temperature (18°C-25°C) before use. It requires the addition of a catalyst and accelerators to start the curing reaction. The correct amount of Accelerator G (1% Cobalt) and Acetyl Acetone should be stirred into the resin. The recommended catalyst for this system is Trigonox 239, which should be added at 2% into the resin and thoroughly dispersed. The geltime can be adjusted by varying the levels of Acetyl Acetone.

Technical Details & Test Data
- Post Curing
Satisfactory laminates for many applications can be made from Crystic VE671-03 by curing at workshop temperature (20°C). However, for optimum properties and long term performance laminates must be post cured before being put into service. Moldings 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. Post curing at 100°C is advisable if moldings are to operate at high temperatures.
