Description
M-CERAMIC 402 – Epoxy Ceramic Wear Compound – High Abrasion
Is a Solvent free Epoxy Ceramic Wear Compound containing Silicone Carbide beads (1.5mm).
The product when cured is particularly suited for extreme fine particle and wet slurry wear environments, typically found in Cement Production, Quarrying and Steel industries.
The product can be applied up to 10mm in a single application without shrinking. Normal application method is by plastic applicator tool, trowel and spatula.
Typical Uses
- Lining for Slurry Pumps
- Wear Resistant lining for Bins & Hoppers
- To Protect Fan Blades & Fan Housings
- Create Wear Plates
- Protect Pipe Elbows
- As a filler for lost Ceramic Wear Tiles
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.
- 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 10°C or less than 3°C above dew point.
Mixing full units or by part-mixing.
- If mixing the whole unit please ensure as much of the base and activator is dispensed from the plastic container onto a clean plastic mixing surface.
- Mix using the spatula provided until a uniform material free of any streakiness is achieved while ensuring no unmixed material is left on the spatula or the mixing surface.
- For part mixing, using a spatula place 5 equal measures from the base unit onto a clean plastic mixing surface.
- Clean the spatula thoroughly and then take 2 equal measure from the Activator unit and place alongside the base measures.
- Mix as above
Use all mixed material within 45 minutes at 20°C.
- The mixed material should be applied directly to the prepared metal surface at a minimum thickness of 6mm using a spatula or applicator tool.
