Description
M-CERAMIC 500 - High Temperature Epoxy Ceramic Coating
The coating is designed principally for the long-term protection of Fluid-Flow and Process Equipment such as Pressure Vessels, Scrubber Units Process Columns ect…
Once cured M-CERAMIC 501 – Epoxy Ceramic High Temperature & Acid Resistant Coating provides a hard-wearing sacrificial barrier, protecting the parent metal from erosion, corrosion and chemical attack.
The product is ideal for water and aqueous/hydrocarbon mixtures at elevated temperatures up to 110°C. Â
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 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:
- Warm 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 7:1 by volume or 18:1 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 20 minutes at 20°C
- Stripe coat all edges, 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 600 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 300 microns using a short-bristled brush.
To enhance the properties of this material, post curing will be required.
- Allow the product to cure of at least 4 hours at 20°C.
- Raise the coating and substrate temperature progressively to 60 – 100°C for up to 8 hours.
Post curing will result in improved mechanical, thermal and chemical resistance properties.
