85ml Two-Part Epoxy Metal Sealant for Waterproof Repairs on Stainless Steel, Copper, and Aluminium

This two-part epoxy casting glue is formulated for creating strong, waterproof seals and carrying out repairs on common metals including stainless steel, copper, and aluminium. Supplied in an 85ml cartridge, it comes as a complete kit with a push rod for application, a scraper for finishing, and sandpaper for surface preparation. It serves both professional tradespeople and DIY enthusiasts tackling tasks from plumbing fixes and automotive repairs to metalcraft and general household maintenance where a durable, waterproof bond is required on metallic surfaces.
Features and Construction

The product is a two-component adhesive system, designed specifically for metal bonding. Its construction centres on the precise combination of its two parts to initiate curing and achieve its final bonded state.
Material and Build
The sealant is composed of two separate components: Part A glue contains epoxy resin and polymer resin, which form the adhesive matrix. Part B glue contains a curing agent and additive, which is necessary to trigger the hardening reaction when mixed with Part A. This two-part epoxy construction is a common method for achieving strong, structural bonds that are resistant to water and many chemicals once fully cured, making it suitable for sealing applications.
Size and Practical Fit
The primary specification provided is the 85ml capacity of the epoxy cartridge. This volume is a practical size for a range of small to medium repair jobs, offering enough material for multiple fixes or a single larger project without being unwieldy. The kit is designed for direct use, including a push rod to extrude the mixed adhesive, a scraper for application and smoothing, and sandpaper to prepare metal surfaces, which can improve adhesion for a more reliable bond.
Uses and Placement

This metal sealant is intended for applications where a waterproof, structural bond between metal surfaces is needed. Its stated compatibility with stainless steel, copper, and aluminium guides its use in relevant contexts.
Event or Professional Use
For professional trades such as plumbing, metal fabrication, or automotive repair, this epoxy can be used for sealing joints, repairing cracks, or bonding components made from the compatible metals. The waterproof nature of the cured epoxy makes it applicable for sealing pipework, repairing metal fixtures, or mending tools and equipment where moisture resistance is a factor, providing a reliable solution in workshop environments.
Everyday Home Use
Around the home, this product is suited for DIY repairs on metal furniture, appliances, gutters, or craft projects. It can mend a broken copper pipe fitting, seal a leak in an aluminium window frame, or reattach a stainless steel bracket. The included tools make it accessible for users to attempt these repairs without needing additional specialised equipment for application and preparation.
Benefits and Buying Value

The value of this product lies in its targeted formulation for metal bonding, the inclusion of necessary application tools, and the option for different purchase quantities to match project scale.
Reuse and Low Maintenance
While the 85ml cartridge is typically for single use until emptied, the multi-unit purchase option (5PCS) allows users to have a supply on hand for future repairs, potentially offering better value for frequent users. A successful repair with a waterproof seal can reduce ongoing maintenance by preventing leaks or failures, extending the functional life of the repaired item. The cured epoxy bond generally requires no additional maintenance once properly applied.
Why Choose This Product
This epoxy sealant offers a focused solution for bonding stainless steel, copper, and aluminium with a waterproof result. Compared to generic adhesives, its specified compatibility with these metals provides clearer guidance for appropriate use. The inclusion of the push rod, scraper, and sandpaper in the kit adds immediate practicality, removing the need to source these basic tools separately. The availability in both single and five-piece quantities also provides flexibility, whether for a one-off job or stocking up for multiple projects.
