How to Use (Step-by-Step Guide)
1. Mix Part A and Part B of the high temperature RTV-2 liquid silicone in a 1:1 weight ratio, stirring thoroughly with industrial equipment in an irregular direction for 2~3 minutes until uniform and bubble-free.
2. Perform vacuum degassing for 2~5 minutes (time varies by viscosity and vacuum strength) to eliminate bubbles, preventing mold or product defects.
3. Pour the degassed silicone slowly into molds or application areas, leveraging good fluidity to fill all details and gaps.
4. Cure at room temperature (25℃) for 4~5 hours, or 80~120℃ for accelerated curing; post-cure at 150℃ for 1 hour to enhance high-temperature stability.
5. Store unused silicone in sealed packaging, indoor storage away from sunlight and rain, use within 10 months; avoid contact with N, P, S-containing compounds to prevent curing failure.
