- Curing
NM Laminering 275 cures at room temperature. Time to achieve full cure may be accelerated by post curing at elevated temperature e.g. 24 hours at 50°C.. It is important that the temperature is ramped up slowly to the final cure temperature. Often is it a combination of thickness and the laminate structure that determines the ramping speed. The optimum cure cycle must be defined for each individual case

- Industrial
- Post work
It is important to further treatment as laminating, filling, etc. occurs when the surface is still like a tacky tape. A dry surface has to be sanded to ensure adhesion to the next layer.
- Application
The mixture of components is very important. A poor mixing results in soft spots in the cured system. Mix thoroughly in a vessel, transfer the mixture into a clean vessel and mix further. Dosage should always be done on a scale with sufficient accuracy.

- Release agents
We recommend film forming release agents such as Marbocote 220.; Wax-based release agents are generally not recommended. For this, trials must be done first
- HIGHLIGHTS
NM Laminering 275 has good wetting to glass fiber, carbon fiber, and polyester and aramid fiber. It is used for manufacture of molds and tools, and cold bakingof wood. NM Laminering 275 is suitable as laminatingepoxy on polystyrene.; NM Laminering 275 is highly water-resistant and therefore suitable for both construction and repair ofthe above mentioned materials.; NM Laminering 275 has a long pot life and low exothermic heat up to layers of 5 mm.; NM Laminering 275 can thixotropated with NM Filler51 for use as adhesive. The adhesion is very good for most materials.
