Addition-Cure Liquid Silicone: Features include no release of low molecular substances during vulcanization, low shrinkage rate (typically less than 0.1%), high temperature resistance, high tear strength, and good fluidity, making it suitable for fine model replication.

Material Ratio and Compatibility Strictly mix according to the specified ratio of silicone and curing agent; incorrect ratios may lead to curing failure or reduced mold performance.
Ensure prototype materials are compatible with addition-cure silicone (e.g., avoid prototypes containing sulfur, phosphorus, nitrogen, or other compounds that may inhibit silicone curing).
Bubble Control Stir silicone at a moderate speed to avoid introducing excessive bubbles; pour slowly during casting to minimize impact.
For prototypes with complex shapes, pour silicone in multiple stages: first apply a thin layer to fill details, then pour the entire volume to reduce bubble retention.
Environment and Temperature The operating environment temperature should ideally be maintained between 20-30°C. Lower temperatures may prolong curing time, while higher temperatures may cause rapid curing, preventing adequate detail filling.
Gypsum releases heat during curing; pay attention to the heat resistance of the mold frame to avoid deformation of the silicone mold due to high temperatures.
