Detailed Technical Specifications

How to Use
1.Precise Weighing: Use a digital scale to accurately weigh components at a strict A : B = 100 : 2 (or 100:3) ratio by weight. Component B (curing agent) is used in very small amounts—accuracy is crucial for successful curing.
2.Initial Mixing: Add Component B to Component A. Mix with a stirrer at low speed, clockwise for 3-5 minutes until the color is completely uniform. Scrape the walls and bottom of the container to avoid unmixed spots.
3.Vacuum Degassing: Pour the mixed silicone into a container placed inside a vacuum degassing chamber. Turn on the vacuum pump and maintain a vacuum of -0.1 MPa for 2-3 minutes, until bubbling stops and the silicone surface settles flat. This is the core step to eliminate bubbles and ensure mold quality.
4.Pouring into Mold: After degassing, promptly and in one go, pour the silicone slowly from the container edge into the prepared master mold. Utilize its good flowability to self-level and fill every detail.
5.Curing: Allow to cure completely at room temperature (25°C) for 4-5 hours before demolding. Avoid vibration or movement. To accelerate, apply mild heat (40-50°C) to reduce time to 2-3 hours.

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:

Q1: How to Choose Between 100:2 and 100:3 Ratios?
A: 100:3 cures slightly faster with higher hardness; 100:2 offers longer pot life and better flexibility. Choose based on ambient temperature and requirements for working time/hardness.

Q2: Why is a Vacuum Degasser Needed? Platinum Silicone Doesn't Require it?
A: The tin-cure silicone chemistry is more sensitive to bubbles during curing. Vacuum degassing is key to ensuring industrial-grade bubble-free molds, significantly improving yield. Some platinum silicones are self-degassing, but degassing is also recommended for highest quality.

Q3: Can it be Used Without a Vacuum Chamber?
A: Yes, but the final mold may contain internal bubbles, affecting casting surface quality and mold life. For low-requirement trials or very small molds, try slow stirring and resting. For formal production, we strongly recommend using a vacuum chamber.

Q4: Can Molds Really be Used 800+ Times?
A: Yes, with proper use (e.g., correct release agent, avoiding forced demolding) and recommended materials (e.g., plaster, cement), molds can achieve this lifespan. Using with resins may reduce it.

5.Q: How to Choose Between This and Platinum Silicone?
A: For ultimate cost-effectiveness, mass production, use with plaster/cement → Choose Tin-Cure. For food-grade needs, highest clarity, or wanting to omit degassing → Choose Platinum. We can advise based on your specific project.
