How to Use (Step-by-Step)
1. Mix Part A and Part B of the RTV Silicone for Custom Mold Manufacturing in a 1:1 weight ratio, stirring thoroughly for 2~3 minutes in an irregular direction until uniform and bubble-free—critical for custom mold precision. 2. Vacuum degas the mixed silicone for 2~5 minutes; adjust time based on viscosity, silicone weight, and vacuum intensity to eliminate bubbles that affect custom detail replication. 3. Pour the degassed silicone into the custom mold master, leveraging its excellent fluidity to fill all complex custom details. 4. Cure at room temperature (25℃) for 4~5 hours, or 80~120℃ for accelerated curing (customized based on your production timeline). 5. Gently demold the cured custom mold; store unused silicone sealed indoors, away from sunlight and rain, and use within 10 months.
