Description
M-CERAMIC 500 - High Temperature Epoxy Ceramic Coating
Is an erosion, corrosion and chemical resistant coating formulated using the latest solvent free epoxy novolac technology, enhanced further with the addition of several grades of high-quality silicone carbide ceramic fillers.
Designed for the long-term protection of fluid-flow and process equipment commonly found in the oil, gas, and chemical industries.
Once cured M-CERAMIC 500 – provides a hard-wearing sacrificial barrier, protecting the parent metal from erosion, corrosion and wear at elevated temperatures up to 130°C continuous immersion dependant on the application.
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 short-bristled brush, squeegee or plastic applicator.
Typical Uses
- Lining for Pumping Systems & Valves
- Lining for Scrubber Units
- Protection for Corroded Heat Exchangers
- High Temperature Coating for Process Equipment
- Wear Resistant Coating for Fans & Fan Casings
- Internal lining for Pipework
Application Guide
- All oil and grease must be removed from the surface using an appropriate cleaner such as 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.
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.
- Mix both Part-A and part-B together in full units as supplied. For small quantities us a mixing ratio of 4:1 by volume or 10:1 by weight
- When mixing both materials, it is particularly important to have a uniform colour that is streak free.
- Use the mixed coating as soon possible after mixing.
Use all mixed material within 30 minutes at 20°C.
- Stripe coat all edges and corners. Apply the coating at minimum 300 microns using a short bristle brush.
- Allow the stripe coat to cure for 4 hours at 20°C.
- The basecoat should be applied at a minimum thickness of 500 microns using a short-bristled brush.
- Ensure the coating is forced into the blast profile.
- Allow the basecoat to cure for approximately 4 hours at 20°C.
- Once the basecoat has cured hard enough apply the topcoat at a minimum thickness of 500 microns using a short-bristled brush.
