BONDIT BLACK Aquarium Sealant 310ml – Vivarium & Tank Silicone

BONDIT BLACK Aquarium Sealant is a black, marine-grade silicone sealant in a 310ml cartridge, designed for aquarium construction, vivarium builds, and any application where a reliable, long-lasting seal is non-negotiable. Whether you're bonding glass panels on a new tank, sealing a flat-pack reptile vivarium, or making good around pumps and pipework, this is a sealant built to handle it properly.

Marine-Grade Silicone Formula

Formulated to marine quality standards, BONDIT BLACK resists UV degradation, ozone, and prolonged saltwater immersion — qualities that translate directly to long-term reliability in humid vivarium or aquatic environments. It will not shrink back after application, and in paste form it is non-slumping, meaning it stays exactly where you put it on vertical joints and glass edges.

Where It Works

• Bonding, bedding, and sealing glass in aquarium construction
• Sealing flat-pack and constructed reptile vivariums
• Creating in-situ gaskets and seals around pumps and pipework to prevent water ingress
• Dust and weatherproofing seals for cabinets in demanding or external environments

Compatible Surfaces

BONDIT BLACK adheres to a wide range of materials commonly used in vivarium and aquarium builds, including glass, ceramics, anodised aluminium, primed metals, timber, and many plastics. Check compatibility with any untreated or specialist plastics before use.

For keepers building or maintaining enclosures to a high standard, BONDIT BLACK provides the kind of structural confidence that cheaper sealants simply don't deliver.
