NM Infusion 664 is not suitable for open mold processes, due to the low viscosity. For such applications, NM Laminering 650 is recomendable. NM Infusion 664 has a very low vapor pressure and is practically as good as free from smell. Vacuum gives no outgassing.
NM Infusion 664 has a low reactivity and the viscosity increases very slowly during the infusion process. Large and complex structures can be infused without problems.
The low reactivity involves a long demoulding time at room temperature curing. Tg should as a minimum reach room temperature before demoulding.

Technical Details & Test Data
- Curing
An increase or decrease of the curing temperature with 10°C gives a halvend resp. doubled demoulding time.
Curing can take place at room temperature or as a post-curing at elevated temperature. Curing at +60°C gives a higher Tg.
Tg development at +23°C curing temperature can be seen in the table below.
