• Safe Formulation: Solvent-free; once fully cured, it is safe for fish, plants, and aquatic life.
• ISO 11600 Compliance: Meets international structural sealing standards; reliable for professional projects.
• UV & Ozone Resistance: Provides long service life against sunlight and atmospheric conditions.

Application Areas

• Aquarium Manufacturing: Bonding glass panels and creating watertight seals
• Glass Structures: Display cases, glass boxes, greenhouse glazing installation
• Waterproofing: Pool edges, fountains, water tank repairs
• Industrial: Metal/aluminum joints, gasket replacement
• General Repairs: Waterproof filling on ceramic and metal surfaces

Frequently Asked Questions

Is aquarium silicone truly safe for fish?

Yes. Once curing is complete (typically 24–48 hours), it is completely harmless. It contains no solvents and will not release harmful substances into water. However, do not fill the aquarium with water until curing is finished.

What Does ISO 11600 – F&G – 25 LM Mean?

This standard defines the performance of structural sealing materials. "F&G" stands for Facade and General use; "25 LM" means movement capability of ±25%. In other words, the silicone can withstand up to 25% expansion or contraction at joints.

How Long Is the Curing Time?

Surface drying occurs within 10–20 minutes. Full curing takes 24–48 hours depending on bead thickness and ambient humidity. For aquarium applications, allow at least 48 hours before filling with water.

Which Surfaces Does It Bond To?

It bonds excellently to glass, aluminum, glazed ceramic, and metal. Surfaces must be clean, dry, and free of grease before application. Priming is recommended for porous surfaces (concrete, wood).

What Coverage Does a 300 ml Cartridge Provide?

300 ml of silicone yields approximately 12–15 meters of bead at 5 mm diameter. For an average-sized aquarium, 1–2 cartridges are sufficient. Plan quantities according to your project size.
