Step-by-Step Usage Guide

1. Prepare a clean, dust-free workspace to ensure mold clarity and precision.

2. Mix Part A and Part B at a 1:1 weight ratio, stir thoroughly for 2-3 minutes until fully blended.

3. Perform vacuum degassing for 2-5 minutes (adjust for viscosity/weight) to remove air bubbles and avoid mold imperfections.

4. Pour the mixed silicone slowly into mold frames, covering all surfaces evenly. 5. Cure at room temperature for 4-5 hours, or accelerate with 80-120℃ heat for quick turnaround.

6. Store unused material sealed indoors, avoid direct sunlight and moisture, use within 10 months.

Application Scenarios & Customer Value
