Letzter Firmenfall über What can be done if silicone for molds cures slowly at room temperature?

Liquid silicone raw materials are widely used in industries that come into direct contact with food due to their advantages such as:

  • High temperature resistance
  • Corrosion resistance
  • Soft feel
  • High mold-making frequency

making them popular with customers. Meanwhile, mold silicone materials from reputable manufacturers are FDA and RoHS certified. When purchasing mold silicone raw materials, the color and hardness can be customized in consultation with the manufacturer. The manufacturer can provide the desired color and ratio; this is the case with Hongtu Silicone. The mold silicone ratio is 1:1. When using, mix the A and B components thoroughly. The curing time at room temperature (around 25 degrees Celsius) is approximately 3-5 hours. Of course, a fast-drying formula is also possible, curing in 30 minutes to 1 hour.

What if the mold silicone cures slowly at room temperature?

Generally, it's cured in an oven. But what if a customer doesn't have an oven? In that case, it will have to cure slowly at room temperature. If you purchase our HANAST mold silicone raw materials, we can adjust the curing time to a slow-curing formula, allowing you ample time for operation (72 hours without curing).

However, for mass production, we recommend using an oven. Typically, heating to around 100 degrees Celsius will fully cure the silicone in about 10 minutes.

Now you know what to do if the curing is slow?

If you need to select the curing time yourself, please purchase our HANAST mold silicone raw materials; we can customize them to your specific needs.
