The LOCTITE EA 3471 is a non-sag, metal-filled epoxy compound that cures at room temperature to form a hard, machinable surface. Its steel-reinforced formula bonds firmly to all common metal substrates, delivering structural integrity without the need for welding or specialized equipment.
Once cured, the compound can be machined, drilled, tapped, filed, or painted to match your exact specifications. This flexibility makes it suitable for both precision applications and general maintenance repairs.

Key Features & Advantages
True Metal-Like Surface After Cure
Loctite EA 3471 solidifies into a hard metallic surface that closely mimics the properties of cast metal. It resists wear and maintains dimensional accuracy in demanding conditions.
Strong Adhesion on All Metal Substrates
The steel-reinforced formula provides superior adhesion on iron, steel, aluminum, copper, and other common metals. No primer is required for most applications.
No Shrinkage, No Depression
Unlike standard epoxy compounds, EA 3471 cures with zero shrinkage. This ensures a flush, stable surface with no cracking or voids after curing.
No Welding or Heating Required
The ambient-cure system eliminates the need for hot work equipment. This reduces downtime and allows repairs in areas where open flame is restricted.
Machinable After Cure
The cured compound is fully machinable. Engineers can drill, tap, mill, and file the repair area to restore precise tolerances.
Wide Temperature Range
With a working range of -30°C to 105°C, this product performs in refrigeration environments, standard machine rooms, and moderate-heat industrial settings.
Applications
Loctite EA 3471 is used across multiple industrial sectors. Common applications include:
Casting defect repair – Fill porosity, cracks, and non-structural voids in iron and steel castings
Machine base and frame repair – Rebuild worn or damaged surfaces on industrial machinery
Fixture fabrication – Create custom fixtures or fill gaps in tooling setups
Container, tank, and valve sealing – Seal leaks and restore structural integrity
Air seal re-lining – Restore worn air seal surfaces without full component replacement
Void filling – Fill gaps, holes, and recesses in metal housings or structures

Frequently Asked Questions (FAQ)
Q1: What surfaces is Loctite EA 3471 compatible with?
EA 3471 bonds to all common metal substrates including steel, cast iron, aluminum, copper, and brass. Surface preparation (cleaning and roughening) improves adhesion.
Q2: Can EA 3471 be used for structural repairs?
No. EA 3471 is designed for non-structural defect repair. It is not rated as a primary structural adhesive. Use it for surface restoration, void filling, and sealing applications.
Q3: How long does it take to cure?
Curing time depends on ambient temperature. At room temperature (~23°C), the compound reaches handling strength in approximately 60–90 minutes and full cure in 24 hours. Higher temperatures accelerate cure.
Q4: Can the cured material be painted or coated?
Yes. Once fully cured, the surface can be sanded, primed, and painted. It accepts most standard industrial coatings.
Q5: Is EA 3471 available for bulk or wholesale orders?
Yes. E-ASIA supports bulk supply, wholesale purchasing, and long-term distributor agreements. Contact us for pricing and availability.
