Product Description

Professional Aluminum Epoxy for Permanent Metal Repairs

Alumbond is a two-component aluminum-filled epoxy repair compound engineered for high-performance industrial and mechanical applications. Formulated with high-purity aluminum particles, advanced curing agents, and premium additives, it delivers exceptional strength, durability, and ease of use.

Designed for professionals, Alumbond provides a non-rusting, non-magnetic aluminum finish, making it the ideal solution for restoring damaged components without replacement.

FEATURES:

• Aluminum-Filled Metal Repair Compound – Professional-grade polymer designed to permanently repair cracks, blow holes, and casting imperfections in aluminum components including radiators, engine blocks, housings, tanks, and HVAC parts
• High-Strength Industrial Performance – Engineered for demanding repairs with 8,600 PSI compressive strengthand 3,500 PSI tensile strength, restoring structural integrity to damaged surfaces
• Machinable After Curing – Once fully cured, the material can be drilled, sanded, tapped, or machined using standard tools, eliminating the need for costly replacements
• Non-Sag Formula for Vertical Applications – Thick paste consistency stays in place, making it ideal for vertical, overhead, and irregular surface repairs
• High Temperature Resistance – Withstands temperatures up to 250°F (121°C), perfect for automotive, HVAC, and industrial environments
• Controlled Working Time – Provides a practical application window for accurate placement and shaping before curing
• Ideal for Casting Defects & Surface Repairs – Specifically formulated for porosity, voids, and surface imperfections in aluminum components
• Trusted Professional Quality – Manufactured by Mastercool, a U.S.-based brand known for reliable tools and repair solutions
