3. Deep Curing & No Shrinkage: Cures fully regardless of thickness, no deformation, ensuring consistent product dimensions and mold precision.
4. Safe & Non-Toxic: FDA, RoHS certified, non-toxic odorless, suitable for food-contact and skin-contact elastic products.
5. Easy Operation: 1:1 mix ratio, simple stirring, supports room/heat curing, no professional skills needed for mass production.
6. Competitive Edge: Compared with ordinary liquid silicone, it has higher elasticity, better durability, and more stable batch performance.
Step-by-Step Usage Guide
1. Prepare a clean, dust-free workspace to ensure material purity and product quality.
2. Mix Part A and Part B at 1:1 weight ratio, stir thoroughly for 2-3 minutes until fully blended.
3. Perform vacuum degassing for 2-5 minutes (adjust by viscosity/weight) to remove air bubbles, avoiding flaws.
4. Pour the mixed silicone into molds or application areas, ensuring full coverage of details.
5. Cure at 25℃ for 4-5 hours, or accelerate at 80-120℃ for quick production; post-cure enhances elasticity and durability.
6. Store unused silicone sealed indoors, avoid sunlight/moisture, use within 10 months.
