Wacker 121 Aquarium Silicone

Wacker 121 Aquarium Silicone Sealant

Wacker 121 Aquarium Silicone Sealant is a high-quality, acetoxy-curing silicone sealant specially developed for aquarium construction and glass bonding applications. It is a one-component silicone sealant that cures at room temperature under the action of atmospheric moisture, forming a permanently flexible, strong, and watertight silicone rubber.

This sealant is supplied in a 300 ml cartridge and is available in clear colour, making it ideal for applications where transparency and clean appearance are critical. Wacker 121 offers excellent adhesion to glass surfaces, ensuring secure bonding and long-lasting sealing in water-holding structures. Its smooth, non-sag consistency allows precise application on vertical and horizontal joints without slumping.

Wacker 121 Aquarium Silicone Sealant is formulated to deliver high tensile strength and strong bonding, making it suitable for aquariums and other glass structures exposed to continuous water pressure. Once cured, the sealant remains flexible, resists ageing, and maintains sealing integrity over long periods of use. It is designed for applications where reliability, clarity, and durability are essential.
