Nils Malmgren AB NM Infusion 664

NM Infusion 664 is an extremely low viscosity epoxy system, suitable for all kind of infusion processes. The system is based on the latest development within the epoxy technology, which means that the low viscosity can be combined with a high Tg (glass transition temperature) even at room temperature curing. Wetting and adhesive properties are very good to all kind of fibers.

Application

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.
