Loctite EA 3463 10 Minute Repair Epoxy Putty

LOCTITE EA 3463 (4oz) is a versatile, steel-filled grey epoxy repair putty engineered for maximum efficacy in metal repair. This industrial-grade adhesive permanently stops leaks in pipes and tanks, preventing costly downtime and equipment replacement caused by cracks, oversized holes, and non-structural defects. Whether you are securing tanks and pipes or smoothing welds and repairing castings, this premium kneadable stick provides a robust, leak-proof seal on all surfaces—including wet and damp substrates.

Why Choose LOCTITE EA 3463?

• Emergency Leak Repair: Quickly seals and plugs leaks in tanks, pipes, and castings under room temperature curing conditions.
• High Compressive Strength: Once fully cured, it exhibits exceptional structural strength and strong adhesion to most rigid surfaces.
• Broad Operating Temperature Range: Maintains its structural integrity in demanding environments ranging from -30 °C to +121 °C (-55 °C to +120 °C limit).
• Steel-Filled Versatility: Ideal for heavy-duty industrial applications, including filling oversized bolt holes and fixing defects in castings.
• Potable Water Certified: Certified to ANSI/NSF Standard 61, making it safe for use in commercial and residential potable water systems up to 82° C.

Simple Application Instructions

1. Clean: For optimal results, clean and sand all surfaces. Ensure they are dry for maximum adhesion, though the putty can still be applied to wet surfaces with a slight reduction in bond strength. (Do not apply to surfaces exceeding 66 °C).
2. Apply: Put on protective gloves. Cut the required amount of material from the stick and remove the clear plastic wrapper. Twist the material to create a spiral pattern of resin and hardener, then knead for 2–3 minutes until a uniform grey color is achieved.
3. Assemble: Firmly apply the mixed putty to the repair patch, hole, or joint. For a perfectly smooth finish, wet a cloth or a gloved finger with water and smooth the surface before it begins curing.

Frequently Asked Questions (FAQ)

What is LOCTITE EA 3463 used for?

LOCTITE EA 3463 is a dual-component, steel-filled epoxy repair putty designed for emergency metal repair. It is specifically formulated to prevent pipes, tanks, and castings from leaking or failing due to mechanical cracks, non-structural defects, or oversized holes.

Can LOCTITE EA 3463 be disassembled?

No, this product forms a high-strength, permanent structural bond once cured. Removal typically requires mechanical abrasion or grinding, as it exhibits high compressive strength and excellent adhesion to the substrate.

Does LOCTITE EA 3463 work on wet surfaces?

Yes. LOCTITE EA 3463 offers robust performance across various conditions and can be applied directly to wet surfaces. However, for maximum bond strength and adhesion, applying it to a clean, dry, and sanded surface is highly recommended.

Is LOCTITE EA 3463 safe for plumbing or water systems?

LOCTITE EA 3463 is certified to ANSI/NSF Standard 61. This means it is approved for use in commercial and residential potable water systems, provided the operating water temperature does not exceed 82° C. It should not be used in pure oxygen or strong oxidizing systems (such as chlorine).
