Vicpricme Metal Glue, 2-Part Epoxy, 4,680 PSI Heavy-Duty Repair

vicpricme

More Details
Main highlights
- STRONG, WATERPROOF & OIL-RESISTANT AFTER FULL CURE:** Cures into a hard, steel-like repair with a stated bond strength of up to 4,680 PSI. The cured epoxy is waterproof and resistant to oil and compatible chemicals, with a stated service-temperature range of -85°F to 356°F. Suitable for properly prepared rigid components in workshops, garages and outdoor equipment repairs. Actual performance depends on surface preparation, joint design, cure conditions and the type of load.
- REPAIR RIGID METAL PARTS, NOT JUST SMALL BONDS:** Vicpricme metal repair epoxy is designed for prepared aluminum, steel, stainless steel and cast iron. Repair rigid brackets, housings, tools, metal fixtures and other non-flexing parts. A practical cold-weld alternative for localized repairs when replacing a part is unnecessary. For best results, confirm material compatibility and prepare the surface before application.
- KNOW THE LIMITS BEFORE YOU REPAIR:** For rigid, non-flexing repairs only. Not recommended for galvanized or zinc-plated parts or surfaces, PE, PP, PTFE, silicone, rubber-like or flexible materials, moving joints, torsion-loaded parts, fuel or brake lines, pressurized plumbing, pressure-critical systems, exhaust manifolds or internal engine cracks. Do not use as a substitute for a safety-critical component or a repair requiring certified pressure containment. Test compatibility and adhesion on the intended substrate before use.
- CONTROLLED 1:1 MIXING FOR MORE PRECISE REPAIRS:** The pre-filled dual syringe helps dispense Parts A and B in the intended 1:1 ratio. Clean and degrease the surface, remove loose rust or coatings, and roughen the bonding area. Dispense and mix both components thoroughly until uniform, apply to the prepared surfaces, align the parts and clamp securely. Use a compatible reinforcement patch, mesh or bracket where appropriate for rigid repairs. Follow the product instructions and allow a full 24-hour cure before use.
- 30-MINUTE WORKING TIME, 24-HOUR FULL CURE:** The 1:1 two-part epoxy gives you time to mix, fill gaps, build up material, align parts and secure the repair. Allow up to 30 minutes of working time and a full 24 hours to cure under the recommended conditions before loading, drilling, sanding or painting. Working and curing times vary with temperature, mix quantity and application conditions.
