Black RTV Silicone is an incredibly strong sealant. It can resist temperatures ranging from -80 degrees Fahrenheit to 500 degrees Fahrenheit, and is resistant to ozone, UV light, moisture and chemicals. In addition, it has a wide range of uses for sealing joints in many materials including metals, plastics, glass and ceramics. Black RTV is also ideal for use in harsh environments with high levels of vibration or extreme temperature changes. Its flexibility allows it to be used on irregular surfaces as well as complex shapes without cracking or drying out over time. It forms a durable rubber-like seal that remains flexible even after hardening so it won’t crack under pressure or wear down quickly due to exposure to the elements. This makes black RTV an excellent choice for making repairs around the home such as fixing leaky faucets and other plumbing issues because its strength ensures a tight bond between two surfaces that will last for years.
