- Usage
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.

- 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.

- Industrial
- Storage
NM Laminering 650 can be stored for a longer period at room‐temperature and be post‐cured later.
- 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.

- HIGHLIGHTS
NM Laminering 625 can be used for injection, but is optimized for hand lay‐up.; NM Laminering 625 has a very low vapor pressure and therefore, the system is almost odorless. Vacuum gives no gas.; Curing can be done at room or at elevated temperature. Post curing should proceed earliest after one day at room temperature.
- Chemical Resistance
- Acetone
- 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.
- Processing Instruction
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
