4. Easy Operation: Excellent fluidity for easy application and filling of gaps; 1:1 mix ratio and dual curing options simplify production and construction.
5. Versatile Safety: FDA-certified Food grade mold silicone available, non-toxic, odorless, suitable for food-related and industrial sealing. 6. Brand Advantage: Standardized production ensures batch consistency; one-stop solutions save procurement and application time, outperforming competitors with unstable sealing performance.
How to Use (Step-by-Step)
1. Component Mixing: Combine Part A and Part B in a 1:1 weight ratio, stirring thoroughly for 2~3 minutes until uniform and free of streaks or air bubbles.
2. Vacuum Degassing: Place the mixed silicone in a vacuum chamber for 2~5 minutes to remove air bubbles, ensuring no gaps in the sealing layer.
3. Application & Filling: Apply or pour the degassed silicone into the area to be sealed, ensuring full coverage of gaps or joints.
4. Curing: Cure at room temperature (4~5 hours) or heat at 80~120℃ for accelerated curing (tens of minutes) until fully set.
5. Post-Curing Check & Storage: Inspect the sealing layer for tightness after curing; store unused silicone sealed indoors, away from sunlight and rain.
