Loctite EA 3471 Fixmaster Steel Putty
Description
repair putty that cures to a metal-like finish and can be
machined, drilled, tapped or filed. Typical applications include
repairing non-structural defects in castings, making jigs and
fixtures, sealing vessels, tanks and valves, resurfacing worn
air seals and filling cavitated areas. This product is typically
used in applications with an operating range of -30 °C to 105
°C.
The graph below shows the shear strength developed with time
on grit blasted steel lap shears at different temperatures and
tested according to ISO 4587.
This product is not recommended for use in pure oxygen
and/or oxygen rich systems and should not be selected as
a sealant for chlorine or other strong oxidizing materials.
For safe handling information on this product, consult the
Safety Data Sheet (SDS).
Proper surface preparation is critical to the long-term
performance of this product. The exact requirements vary with
severity of the application, expected service life, and initial
substrate conditions
To achieve a 6 mm (.25 in) thickness, the coverage rate will
be 278cm² (43in²) for 0.45kg (1lb), excluding overthickness,
repairs, etc.
Any voids, pinholes, or low thickness areas found in the
coating should be repaired by lightly abrading, cleaning, and
applying further product.
Immediately after use clean tools with suitable cleaner, e.g.
Loctite®
7070™ or a solvent such as acetone or isopropyl
alcohol. Once cured, the material can only be removed
mechanically

TYPICAL CURING PERFORMANCE

GENERAL INFORMATION
This product is not recommended for use in pure oxygen
and/or oxygen rich systems and should not be selected as
a sealant for chlorine or other strong oxidizing materials.
For safe handling information on this product, consult the
Safety Data Sheet (SDS).
Surface Preparation
Proper surface preparation is critical to the long-term
performance of this product. The exact requirements vary with
severity of the application, expected service life, and initial
substrate conditions
Directions for use:
- Remove dirt, oil, grease, etc. with a suitable cleaner, e.g.
high pressure water cleaning system using Loctite® SF
7840™ (Loctite®
Natural Blue®
cleaner/degreaser). - Blast all surfaces to be coated with a sharp edged angular
grit to a depth of profile of 75 to 100 microns and a degree of
cleanliness of Near White Metal (SIS SA 2½ /SSPC-SP 10). - After blasting, metal surfaces should be cleaned with
waterless cleaner, e.g. with Loctite® SF 7611™ (Loctite®
Pro
Strength Parts Cleaner), and be coated before any oxidation
or contamination takes place. - Metal that has been in contact with salt solutions, e.g.
seawater, should be grit blasted, high-pressure water blasted,
and left for 24 hours to allow any salts in the metal to sweat to
the surface. A test for chloride contamination should be
performed. The procedure should be repeated until chloride
concentration on the surface is below 40 ppm.
Application
- Mix resin and hardener according to mix ratios listed or
transfer entire kit onto a clean and dry mixing surface and
mix material vigorously until a uniform color is obtained. - Apply material to prepared surface by first forcing a thin
layer deep into the texture of the substrate. - Then Immediately build up to the desired finished
thickness. - If using to rebuild shaft, the following applies:
- Machine the worn area down 3 mm (0.125 in) to
produce a square shoulder on part. The material is
stronger with a square edge versus a feathered
edge. - Machine a spiral cut in bottom of area to be repaired
to provide mechanical keying into surface. - Apply excess product to ensure small shrinkage
during cure does not produce depression. - Machine the surface to original dimensions prior to
full cure, as the product is very wear resistant.
Inspection
- Visually inspect for pinholes and misses just after
application. - Once the coating has cured, repeat visual inspection to
confirm it is free from pinholes, misses and mechanical
damages. - Control thickness of the coating, especially in the critical
points. - Perform a test with a holiday detector to confirm coating
continuity.
Coverage
To achieve a 6 mm (.25 in) thickness, the coverage rate will
be 278cm² (43in²) for 0.45kg (1lb), excluding overthickness,
repairs, etc.
Repairs
Any voids, pinholes, or low thickness areas found in the
coating should be repaired by lightly abrading, cleaning, and
applying further product.
Clean-up
Immediately after use clean tools with suitable cleaner, e.g.
Loctite®
7070™ or a solvent such as acetone or isopropyl
alcohol. Once cured, the material can only be removed
mechanically
Technical Tips for Working With Epoxies
Environmental Conditions
- Relative humidity: <85%
- Ambient temperature: >15°C (60F) and rising
- Substrate temperature must always be 3°C (7F) higher than the dew point to avoid condensing moisture on parts.
- The higher the temperature, the faster the cure.
- The larger the mass of material mixed, the faster the cure.
- Store epoxy at room temperature.
- Pre-heat repair surface until warm to the touch.
- Mix epoxy in small masses to prevent rapid curing.
- Cool resin/hardener component(s).
