Pro Tip: For translucent or marbled effects, slightly under-mix the pigment to create a swirled design.

Pouring Silicone into the Mold

With your silicone properly mixed, it’s time to pour:
1. Slow and Steady Wins the Race – Pour the silicone in a thin, controlled stream to minimize air bubbles. Start from one corner and let it flow naturally into crevices.
2. Fill in Layers for Complex Designs – If your keychain has intricate details (like embossed logos or 3D textures), pour in layers, allowing each to partially set before adding the next.
3. Vibrate or Tap the Mold – Gently tap the mold on a flat surface to release trapped air bubbles. A vibrating table can be useful for professional-grade results.
Example: If your custom silicone keychain design includes a company logo, ensure the silicone fully fills every detail by using a toothpick to guide the material into fine lines.

Curing for Optimal Strength

Curing time varies based on the silicone type and environmental conditions:

• Room-Temperature Vulcanizing (RTV) Silicone – Typically cures in 4-24 hours. Warmer temperatures speed up the process.
• Platinum-Cure Silicone – Offers a faster cure (30 minutes to 4 hours) and is ideal for detailed designs.

Tip: Avoid moving or demolding too early—patience ensures your keychain retains its shape and durability.

Demolding Your Silicone Keychain

Once fully cured, carefully remove your keychain from the mold:
1. Flex the Mold Gently – Most silicone molds are flexible, allowing you to peel them back without damaging the keychain.
2. Use a Release Agent (If Needed) – For stubborn designs, a light spritz of mold release spray beforehand can help.
3. Trim Excess Flash – Some silicone may seep into mold seams, creating thin edges. Use fine scissors or a craft knife for a clean finish.
Creative Idea: For a unique touch, layer different colored silicones or embed small charms before the final pour.

Finishing Touches for a Professional Look

A well-finished keychain elevates its appeal. Consider these enhancements:
