How to use:
1.A and B must be mixed evenly into a clean plastic or metal container, The bottom and walls of the container must be scraped well to ensure that the silicone is mixed with the curing agent.

2.The pre-operation time of the mixed is 30-40 minutes at room temperature, and the product prototype is poured by vacuum defrosting.The product can be cured completely at room temperature of 3-4 hours and heated at 80-120ºC for 30 minutes.

3. When pouring or brushing mold for medium or large products, it is recommended to pour or brush 2-3mm thick silica gel on the surface of the product to fully and completely contact with the prototype.

4.At  25ºC, A/B is fully mixed and stored safely for 30-40 minutes.The higher the temperature, the shorter the storage time.

Package: 10KG, 20KG, 25KG, 200KG or according to customer requirements.
