Addition-type silicone is formed by adding a platinum catalyst. Once the platinum catalyst comes into contact with elements containing nitrogen, sulfur and phosphorus or heavy metal compounds (lead, etc.), or if smoking is allowed in the operating space, the nitrogen, sulfur and phosphorus elements will react with them, thereby consuming the platinum component. This results in the lack of the catalyst necessary for forming in the addition-type food-grade environmentally friendly liquid silicone. As a result, the food-grade silicone will not cure, or will cure incompletely, and will become sticky and sticky.

Solution to non-curing of addition-type liquid silicone:
1. Stir evenly and add the correct ratio (1:1 or 10:1)
2. Do not contact with nitrogen, sulfur, phosphorus elements or heavy metal compounds, such as sulfur, resin, ordinary sludge, etc.
3. You can apply platinum water or a layer of release agent on the product that is easy to react to it to play an isolation role.
Friendly reminder: When using two-component liquid silicone, you need to pay attention to the following points:
1. Condensation type silicone and addition type silicone cannot be mixed. The container that has been used for condensation type silicone needs to be cleaned before using addition type silicone, otherwise it will cause silicone poisoning.
2. Addition type silicone is a platinum catalyst. Water, impurities, organic tin catalysts, acids, alkalis and other organic substances containing sulfur, phosphorus and nitrogen can affect the curing of the glue. Do not mix or contact these substances when using it.
3. Do not add color or powder to the silicone before testing to avoid the glue from reacting with the catalyst and not curing.
4. The silicone and curing agent must be mixed and stirred strictly according to the ratio requirements to prevent changes in the hardness of the silicone due to improper ratio.
