Description
M-CERAMIC 200 - Epoxy Ceramic Coating
Is a solvent free Epoxy Coating with the addition of graded silicone carbide fillers. Once cured the material offers excellent erosion and corrosion resistant properties.
The product is designed for the long-term protection of Worn Pumps Components or for plant and equipment, suffering material lose due to erosion, corrosion such as Heat Exchangers.
The material is supplied as a 2-component product (PART A & PART B), that requires mixing before use, once mixed the product can be applied directly to prepared metal surfaces by brush, squeegee or plastic applicator.
Typical Uses
- Repair Worn Pump & Valve Components
- Protect Ships Rudders, Bow Thrusters & A-Frames
- As a coating for Condensers & Heat Exchangers
- Wear Resistant coating for Fan Casings and Blades
- As a smooth lining for Internal Pipe Protection
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 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 3:1 by volume or 8:1 by weight
- When mixing both materials, it is particularly important to have a uniform light grey or dark grey fluid that is streak free.
- Once mixing is complete, use the mixed paste as soon possible after mixing.
Use all mixed material within 20-25 minutes at 20°C.
- Apply the mixed material directly to the prepared surface as soon as possible after mixing. For best results the material has been designed to be applied as a two-coat system.
- Basecoat should be applied directly to prepared and cleaned metal surface at a minimum wet film thickness of 250 microns. (dark grey fluid) using a short-bristled brush, spatula, squeegee or plastic applicator.
- Topcoat should be applied directly over the basecoat at a minimum wet film thickness of 250 microns. (light grey fluid).
- The topcoat should be applied over the base coat as soon as possible after application but not exceeding 6 hours, using a short-bristled brush, spatula, squeegee or plastic applicator.
