The Effect of Temperature on the Curing of Liquid Silicone

The temperature change is crucial for the vulcanization process, and the vulcanization time in cold and high-temperature areas is completely different, with obvious speed. rtv2 liquid silicone for mold There are two types of vulcanization methods, greenhouse vulcanization and heated vulcanization. Room temperature vulcanization refers to the natural vulcanization process of flattened silicone gel at room temperature; Heating vulcanization accelerates the process of liquid silicone vulcanization by raising the temperature of the flattened silicone gel, and the difference between the two methods lies in the temperature change.
Greenhouse vulcanization is also divided into regional types. In cold regions, the greenhouse temperature is still very low, and the vulcanization process will be long. Therefore, quick-drying agents can be added to accelerate the vulcanization time (control the dosage of quick drying). In areas with high temperatures, they are not affected by climate, and there is not much difference in indoor and outdoor temperatures. The vulcanization time is normal.

It is recommended that customers use room temperature vulcanization during winter, preferably during the day. If heating vulcanization is used, climate change has little impact on the vulcanization of mold silicone. The heating vulcanization method can control the temperature to improve the vulcanization speed, but it is important to control the temperature not too high.
