Bostik Marine Silicone is a waterproof silicone sealant suitable for fish tanks and heavy duty marine work. The clear, one-part bostik marine silicone cures to form a permanently flexible, watertight bond. It offers strong adhesion to non-porous surfaces and maintains flexibility across a wide temperature range from -40°C to 100°C. The formulation is resistant to UV, weathering, ageing, and water exposure, while also providing chemical resistance against diluted acids, alkalis, and household detergents. Its non-sag consistency supports vertical application, and it contains no fungicides, making it suitable for aquarium construction.

Surface Compatibility

Bostik Marine waterproof silicone adheres to a wide range of non-porous materials including glass, ceramics, enamel, porcelain, coated wood, painted surfaces, stainless steel, aluminium, and selected plastics and rubbers. It also functions as an adhesive where an elastic, gap-filling bond is required.
