Does liquid silicone generate temperature when it cures?

Liquid silicone is generally two-component room temperature vulcanized silicone rubber, and some are heated and molded to cure. The materials are environmentally friendly, with high grades passing food grade FDA contact, medical grade, etc. Due to its considerable ozone resistance, high and low temperature resistance, acid and alkali aging resistance and good operability, it is often used in silicone molds, silicone products, adult appliances, pad printing, silicone rollers, film and television props, prosthetics, silicone models, Potting insulated areas.
Since liquid silicone has good operability, what changes will occur during operation and curing? Will high temperatures occur? Below Hanast will give you some popular science.
The curing conditions of liquid silicone need to be matched with a curing agent. The condensation type is cured by organic tin, and the addition type is platinum catalyzed. When operating both types of silica gel, you need to add the matching B component liquid. After mixing evenly, it begins to react slowly at the adjusted "operating time". The semi-hanging fluid liquid slowly thickens and stops flowing until it solidifies. whole. No radioactive substances are produced during operation and curing, and no high temperatures are produced. Therefore, it is relatively safe to operate liquid silicone, compared with other synthetic materials.
