M-METAL 600 - Metal Epoxy Putty - Rapid Cure
Is solvent free, epoxy repair and rebuilding compound, suitable for emergency repairs to metal or plastic components suffering material loss due to mechanical damage, erosion, corrosion or chemical attack.
M-METAL 600 – Metal Epoxy Putty – Rapid Cure when mixed the material is tolerant to poor surface conditions and can be applied directly to damp or wet surfaces, providing all loose material is removed before application.
The material is supplied in two parts with a base and activator, once mixed together, provides a smooth grey paste. The mixed the material can be applied in a single coat up to a thickness of 20.0mm without slumping, allowing for faster repair times and return to service.

- As a Structural adhesive
- All oil and grease must be removed from the surface using an appropriate cleaner such MEK or similar type solvent.
- All surfaces must be abrasive blasted to ISO 8501/4 Standard SA2.5 (SSPC SP10/ NACE 2) minimum blast profile of 75 microns using an angular.
- Once blast cleaned, the surface must be degreased and cleaned using MEK or similar type solvent.
- All surfaces must be coated before gingering or oxidation.
- Mechanical tools use a handheld mechanical grinder with a coarse grinding pad or rotary wire brush. Ensure all loose material and as much surface contamination is cleaned from the surface.
- Hand tools use a wire brush or coarse emery cloth to abrade the surface. Ensure all loose material and as much surface contamination is cleaned from the surface.
Ensure the surface is wiped with an appropriate solvent cleaner such as MEK prior to and after abrading the surface.
Prior to mixing please ensure the following:
- The base component is at a temperature between 15-25°C.
- Do not apply the material when the ambient or substrate temperature is below 5°C or less than 3°C above dew point.
- Mix both Part-A and part-B together in full units as supplied. For small quantities us a mixing ratio of: 1:1 by volume or 1:1 by weight
- When mixing both materials, it is particularly important to have a uniform grey paste that is streak free. Once mixing is complete, use the mixed paste as soon possible after mixing.
Use all mixed material within 5 minutes at 20°C.
- Using a spatula or applicator tool, apply the material to the prepared repair area.
- Ensure the product is pressed into any holes, scars or cracks.
- Once the repair has been completed smooth off any imperfections using a gloved hand with a little water.
- Minimum – the applied material can be over-coated as soon as it is touch dry.
- Maximum – the over-coating time should not exceed 4 hours.
Where the maximum over-coating time is exceeded, the material should be allowed to harden before being abraded or flash blasted to remove surface contamination.
