Check stockWhat Loctite EA 3472 is for
The castable member of the family. Where 3471 is a putty you trowel on, 3472 is a pourable liquid that flows into cavities and hard-to-reach areas a putty cannot fill — anchoring and levelling machinery, filling voids, casting core moulds, sealing leaking pipes. Steel filled, so it still cures to a metal-like finish, and the 1:1 mix means nothing needs weighing.
Key features
- Castable liquid — reaches areas a putty cannot
- Steel filled; cures to a metal-like finish
- 1:1 mix by weight and by volume — no weighing
- 70 N/mm² compressive strength
- 25 N/mm² lap shear on grit-blasted mild steel, 20 on aluminium
- 40 minute pot life on a 200 g mass
- Anchoring, levelling, cavity filling and core moulds
- Operating range −20°C to 120°C
Typical applications
- Metal rebuilding
- Pump housings

How to use it
- Remove dirt, oil and grease with a high-pressure water cleaning system and a Loctite cleaner/degreaser.
- Grind down all skip welds, weld spatter and surface roughness. Fill undercuts and pinholes. Grind every projection, edge, high point and fillet to a radius of at least 3 mm, and round all corners.
- Grit blast to a profile depth of 75–100 microns and a cleanliness of Near White Metal (SIS SA 2½ / SSPC-SP 10). For immersion service, White Metal (SIS SA 3 / SSPC-SP 5) is required.
- After blasting, clean with a residue-free solvent cleaner and coat before oxidation occurs.
- Metal that has been in seawater must be grit blasted, high-pressure water blasted, then left 24 hours for salts to sweat out. Test for chloride and repeat until below 30 mg/m² (3 µg/cm²), then blast and clean again.
- Mix vigorously to a uniform colour. Force a thin layer deep into the surface texture first, then build up to the finished thickness immediately.
- Inspect for pinholes and voids after application and again once cured.
Handling and storage
- Relative humidity below 85%; ambient temperature above 15°C and rising.
- Substrate temperature must be at least 3°C above the dew point, or moisture condenses on the part.
- Working time and cure depend on temperature and mass — the larger the mixed quantity, the faster it goes off.
- To speed cure in the cold: store the epoxy at room temperature and pre-heat the repair surface until warm to the touch.
- To slow cure in the heat: mix in small masses and cool the components first.
- Store unopened and dry, ideally 8°C to 21°C; outside 8–28°C the properties can be affected.
EA 3472 or EA 3471?
Same job, different consistency. 3472 pours — use it to fill a cavity, level a machine base, anchor a bolt, or reach a void a trowel cannot. 3471 is a putty that stays where you put it, including on a vertical face, and machines to a metal finish. 3472 is also marginally stronger in compression, 70 against 61.7 N/mm². For the equivalent pourable grade in the Devcon range, see Devcon Plastic Steel Liquid (B).
