1. Weigh components A and B in 1:1 ratio, mix thoroughly, then inject into components requiring potting protection. Injection along one side of the wall reduces air bubble generation.
2. Place sealed components for self-bubble discharge. For optimal results, vacuum defoam mixed rubber before potting. Cures at room temperature with elasticity developing within 1-6 hours.
- Avoid light and heat exposure while maintaining sealed conditions
- Transportable and storable as non-dangerous goods
- 1-year shelf life at 25℃
- Standard packaging: Component A - 25KG plastic drum; Component B - 25KG plastic drum
- Custom packaging options available
