The NLG GUH-12A adhesive and hardener splicing manual provides mixing ratios, tool list, bonding steps, and press conditions.
This manual describes the tools and materials required for the NLG GUH-12A adhesive and hardener process, including the NLG press, process paper, steel plate, and cutter. It also lists the shelf life of the adhesive and the recommended mixing weight ratio.
The bonding procedure is detailed step‑by‑step, covering surface preparation, application of the adhesive, drying time, second coat, press placement, and post‑press trimming. Press conditions such as temperature tolerance and cooling requirements are also specified.
| Shelf life (sealed) | 1 year |
|---|---|
| Mixing weight ratio | 10:1 (adhesive:hardener) |
| Shelf life after mixing | 8 hours (4 h in summer) |
| Press temperature tolerance | ±5 °C |
The recommended mixing weight ratio is 10 parts adhesive to 1 part hardener.
After mixing, the adhesive remains usable for about 8 hours, or 4 hours in summer conditions.
The press temperature should be set to the target value with a tolerance of ±5 °C, and the splice should be removed after the temperature falls below 40 °C.
