How to Use
Standard Operation Steps (Based on 1:1 Ratio)
1.Prepare & Weigh: Clean containers, accurately weigh at 1A : 1B.
2.Vacuum Degas (Optional but Recommended): Degas Part A or B (especially high-viscosity models) before mixing to reduce bubbles.
3.Mix & Stir: Stir slowly and thoroughly for 3-5 mins until uniform color, avoid vigorous stirring to minimize air bubbles.
4.Second Degassing: Vacuum degas the mixture again for 1-2 mins.
5.Pour & Cure: Pour slowly into mold, cure at RT (25°C) for 3-5 hrs, or accelerate at 60°C for 20-30 mins.
Precautions for Mold Silicone:
1. Adjust the amount of curing agent based on temperature—reduce it in high temperatures. Excessive curing agent will cause the mold to harden and become brittle; insufficient curing agent will prolong the working time.
2. To prevent changes in mold silicone properties, it is recommended not to add silicone oil.
3. For optimal mold performance, allow the mold to cure for at least 24 hours before use.
4. The curing speed of this product is closely related to ambient temperature. Higher temperatures accelerate curing. Users may adjust the amount of hardener based on ambient temperature to achieve the desired curing speed.
Shelf Life:
Unopened packaging at room temperature (25°C): 12 months. Finished silicone molds can be stored for up to six months without loss of performance.
Storage and Transportation:
1.Mold silicone should be stored at room temperature in a dry, sealed container. Avoid contact with water to prevent deterioration.
2.This product is classified as non-hazardous for transportation.

FAQ:
1.Q: Why does the silicone not cure or remain tacky?
A: The most common cause is contact with inhibitors. Ensure tools/containers haven't contacted materials containing sulfur, tin, amines, etc. (e.g., some rubbers, curing agents), and strictly avoid mixing with water or alcohol. Conduct a small test batch first.
2.Q: How to choose hardness?
A: It depends on your application. Use softer grades (e.g., Shore A 10-20) for complex patterns, deep molds for easier demolding. Use harder grades (e.g., Shore A 25-40) for flat molds requiring support.
3.Q: How large a mold can be made?
A: Theoretically unlimited in size due to deep cure capability. For very large pours, consider mixing in batches or implementing heat dissipation during curing.
4.Q: Do you offer small sample orders?
A: Yes, we provide 1kg/set sample kits for testing and verification.
