- Features and Benefits
Crystic VE 679-03PA has excellent blister resistance and significantly reduces the occurrence of print through, to produce durable moldings with an enhanced surface finish.
Applications & Uses
- Applications
- Composites End Use
- Formulation Guidelines
Crystic VE 679-03PA must be thoroughly stirred and allowed to attain workshop temperature (18 °C – 20 °C) before use. It needs only the addition of a catalyst to start the curing reaction. The recommended catalyst is Trigonox 249, which should be added at 2 % into the resin.
- Applications
Crystic® VE 679-03PA is recommended for use as an infusion resin with a wide range of gel times with various catalysts.
