Description
M-METAL 100 - Metal Epoxy Putty - Standard Cure
Is a multi-purpose, engineering grade, epoxy metal repair putty? The product is suitable for repairs to metal components suffering material loss due to mechanical damage, erosion, corrosion or wear.
M-METAL 100 exhibits superior bond strength to grit-blasted surfaces but can also be used on manually prepared repairs areas.
The product can be applied up to 20mm in a single application without shrinking. Once cured M-METAL 100 can be drilled tapped machined or sanded to suit the repair profile.
Typical Uses
- Worn or damaged pump shafts
- Filling pitting corrosion
- Resurfacing pump housings
- Cracked pump or valve casings
- Scored hydraulic rams
- Worn bearing housings
- Damaged flanges
- Leaking tank seams
- Worn keyways
- Cracked engine blocks
- Structural adhesive
Application Guide
- 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.
PLEASE NOTE: For salt contaminated surfaces the substrate must be pressure washed with clean water and checked for salt contamination, please refer to the surface preparation and pre-application guide for further information.
- All oil and grease must be removed from the surface using an appropriate cleaner such as MEK.
- All surfaces must be mechanically abraded using handheld grinders to ISO 8501/4 ST3 (SSPC SP3 ST3).
- Once abraded, the surface must be degreased and cleaned using MEK or similar type material.
- All surfaces must be repaired before gingering or oxidation occurs.
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.
If part mixing the unit of material please follow the instructions below:
- Using the spatula provided place 3 equal measures from the base unit onto the mixing board
- Clean the spatula
- Then take 1 equal measure from the activator unit and place alongside the base
- Mix the 2 components together until you have a streak free mix (mid grey) paste when mixing is complete.
- Ensure there is no unmixed material on the spatula or mixing board
If mixing a complete unit of material (1kg/3kg) please follow the instructions below:
- Dispense as much of the base and activator units onto a clean mixing surface.
- Mix the 2 components together until you have a streak free mix (mid grey) paste when mixing is complete.
- Ensure there is no unmixed material on the spatula or mixing Surface
Use all mixed material within 30 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 6 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.
