ASI 509 Aquarium Silicone Sealant - BLACK- 10.2 Fluid oz Cartridge
Product Description
ASI 509 Aquarium Safe 100% RTV Silicone is a professional-grade, one-component RTV silicone sealant specifically designed for aquarium manufacturing, assembly, repair, and other applications requiring a durable, waterproof, permanently flexible seal.
Formulated as 100% RTV silicone, ASI 509 cures into a durable rubber that is safe for aquatic life when properly cured. Its excellent clarity and strong adhesion to properly prepared glass make it particularly well suited for aquarium construction and repair. The thick, non-sag formulation also allows the sealant to be applied effectively to vertical and overhead surfaces.
The silicone can be used in both freshwater and saltwater aquariums and is designed to create a reliable waterproof seal that maintains flexibility over time. It is also suitable for applications involving aquarium filters, glass viewing panels, terrariums, and related manufacturing or repair work.
