Can liquid silicone be stored in the refrigerator?
Two-component liquid silicone (after mixing A/B materials)
Curing mechanism: After mixing component A (silicone body) and component B (curing agent), chemical reaction occurs and cures (usually condensation reaction or addition polymerization reaction).
Refrigeration effect:
It can slow down the curing time. Low temperature will reduce the chemical reaction rate, thereby extending the operation time (applicable scenarios: need to extend the time of manual operation or small-scale production).
Specific impact:
For example, the curing time after mixing at room temperature is 30 minutes. If refrigerated to 5℃ (refrigerator temperature), the curing time may be extended to 1-2 hours (specific reference to the temperature-curing time curve provided by the supplier).
However, it should be noted that too low temperature may cause the viscosity of silicone to increase (thicken) and affect fluidity. It needs to be restored to room temperature (or heated to about 25℃ in a warm water bath) before use to avoid affecting the molding effect.
Precautions:
The mixed silicone needs to be sealed and stored in the refrigerator to avoid contact with water vapor (some condensation silicone will accelerate curing when exposed to water).
The refrigeration time should not exceed 24 hours, otherwise it may affect the final performance after curing (such as decreased elasticity and strength).
