Applications & Uses
- Use
NM Laminering 650 can be used for both injection and hand lay‐up. Pot life is extremely long, which means that it is possible to work with large objects without problems. The system with NM Härdare 650 F can be accelerated with NM Accelerator 254. Accelerator is not recommended for injection due risk of blistering.
NM Laminering 650 has a very low vapor pressure and therefore, the system is almost odorless. Vacuum gives no gas in combination with NM Härdare 650 B, NM Härdare 650 M or NM Härdare 650 F.
- Processing instructions
The mixture of components is very important, poor mixing may results in soft spots.
Mix thoroughly in a container, transfer the mixture into a clean container and mix further. Dosage should always be made on a scale with sufficient accuracy or a well calibrated dosage system.
Application is best done with a roller, but can also be done with a brush.
- Surface Preparation
Film forming release agent is recommended, for example Marbocote 220. Wax‐based release agents are normally not recommended and test should be performed before use of these types.
- Uses
NM Laminering 650 can be used in combination with our hardener:
- NM Härdare 650 B, approx. 180 min. pot‐life.
- NM Härdare 650 F, approx. 90 min. pot‐life.
- NM Härdare 650 M, approx. 120 min. pot‐life.
- Post work
By hand lay‐up, it is important that before further treatment as laminating, filling, etc. occurs, it is done when the surface is still tacky.
A dry surface must be sanded to ensure adhesion to the next layer.

Technical Details & Test Data
- Curing
Curing can take place at room temperature or as a post‐curing at elevated temperature.
NM Laminering 650 should first cure at room‐ temperature (20 – 23°C / 68 – 73°F) for 16 ‐ 24 hours before post‐curing.
A typical curing cycle could be one day at 23°C / 73°F and then a post‐cure at 50°C / 122°F for 16 hours, or alternatively four hours at 100°C / 212°F.
It is important that the temperature is ramped up slowly to the final curing temperature. Normal increases are between 0.1 ‐ 0.3°C per minute. It is often a combination of thickness and laminate structure, which determines the speed. The optimum cure cycle must be determined for each case.
