Soudal Silirub AQ Aquarium Silicone Sealant – 300ml

Soudal Silirub AQ Aquarium Silicone Sealant – 300ml

Aquarium glass sealant with important construction limits

Silirub AQ is a silicone adhesive-sealant for suitable glass aquarium and terrarium construction. Choose the clear or black 300 ml option. It remains elastic after curing, but the joint and glass design must be suitable for the load.

Safe after full cure does not mean safe to fill immediately

Soudal states that the product is chemically neutral after curing and contains no fungicide toxic to fish. Keep the aquarium empty until the sealant is fully cured. Skin formation is not full cure; the depth of the bead and conditions affect curing.

Apply to rigid, clean, dry, dust-free and grease-free surfaces. Soudal calls for a preliminary adhesion and compatibility test and ventilation during use and curing. Follow the current label and technical data sheet for the full procedure.

Check the construction rather than assuming any pond window is suitable

The current Soudal technical data sheet limits the aquarium application to constructions meeting DIN 32622, with maximum dimensions of 200 × 60 × 60 cm, correct glass thickness and sufficient reinforcement. It specifies a minimum bond thickness of 1 mm.

Do not use a general aquarium-silicone description as approval for a larger structural pond window, a different substrate or a liner repair. Those applications need a sealant and joint design specifically approved for the materials, dimensions and loading.

Compare pond sealants and adhesives by application and substrate. Selecting an aquatic product is only the first step; preparation, joint design and curing still have to suit the installation.
