Silicone mold is a type of condensed silicone that solidifies by absorbing water from the air. During the production process of silicone,addition liquid silicone rubber the water is evaporated dry without adding an appropriate amount of water, resulting in this phenomenon. addition rtv silicone Solution: This phenomenon is not a product quality issue, but rather occurs due to the lack of control over moisture, improving the storage life of silicone, and ensuring a long shelf life. As long as 0.05% moisture is added appropriately and stirred evenly when using silicone, some problems can be solved.
