Water Resistance
Silicone Water Resistance
Silicone is highly water-resistant, making it an excellent choice for plumbing applications that involve exposure to moisture and water. It forms a waterproof seal that prevents leaks and inhibits the growth of mold and mildew. Silicone remains unaffected by water, humidity, or high water pressure, making it ideal for areas prone to constant moisture, such as bathrooms, kitchens, and outdoor plumbing fixtures.
Plumbers Putty Water Resistance
Plumbers putty offers good water resistance, but it is not entirely waterproof. While it can create an effective seal against sinks, drains, and faucets, it may not provide the same level of protection against prolonged exposure to water or high water pressure. Over time, excessive moisture may cause the putty to degrade or lose its seal, potentially leading to leaks or water damage.
Durability
Silicone Durability
Silicone is known for its exceptional durability and longevity. It can withstand extreme temperatures, UV radiation, chemicals, and general wear and tear. Silicone seals can last for many years without deteriorating or losing their effectiveness.
