1:1 Mix, 15-Minute Mold: Your Ultimate Guide to Silicone Putty Casting!

Why This Silicone Putty is a Must-Have

 Instant Mold Making – Cure in 15-20 minutes (faster than liquid silicone!)
 Perfect Details – Captures even fingerprints and fine textures
 No Measuring Hassle – Simple 1:1 mix ratio by weight
 Reusable & Durable – Make multiple casts from one mold


Gathering Your Supplies

Here’s what you’ll need:

  • Silicone Putty (Components A + B) – The magic duo that hardens into a flexible mold

  • Object to Mold – Jewelry, toys, coins, or even organic items like leaves

  • Scale (Optional) – For precise 1:1 mixing (eyeballing works too!)


Step-by-Step Guide

1. Mixing (Pot Life: 3 Minutes! ⏳)

  • Ratio: Combine equal parts A and B by weight (e.g., 50g A + 50g B).

  • Knead Fast! Mix thoroughly for 30 seconds until uniform in color (no streaks!).

  • Pro Tip: Work on a clean surface to avoid dirt in your mold.

2. Press & Shape (Work Quickly!)

  • Flatten the putty into a pancake shape.

  • Press your object firmly into the putty (push into fine details first).

  • For 3D molds: Cover the object completely with extra putty.

3. Cure (15-20 Minutes at 25°C)

  • Let it sit undisturbed—no peeking!

  • Cold room? Warm the putty slightly to speed up curing.

4. Demold Like a Pro

  • Gently peel the silicone away from your object.

  • Stuck? Flex the mold or use a dull tool to pry edges carefully.

5. Cast Your Creations!

Pour resin, wax, or even chocolate into your new mold. Repeat endlessly!


Pro Tips for Perfect Molds

  • Small Objects? Use less putty to save material.

  • Deep Details? Press the putty in layers to avoid air pockets.
