Silicone sealant is a flexible, waterproof material used to fill gaps and seal joints in various applications. It is commonly used in construction, plumbing, and automotive industries due to its durability and resistance to temperature changes, moisture, and chemicals. This sealant adheres well to surfaces like glass, metal, and plastic, making it ideal for sealing windows, doors, and bathtubs. Unlike traditional caulks, silicone sealant remains elastic over time, allowing it to expand and contract without cracking, ensuring a long-lasting seal.
