While TC Ceramic is designed to bond effectively to most surfaces, certain applications—particularly bare metals and high-exposure environments—may require a primer to ensure optimal adhesion and long-term durability.
Recommended Primers Based on Surface Type:
- Bare Metal Surfaces:
- For metal surfaces that are uncoated or untreated, applying a red zinc oxide primer is recommended.
- Why? Zinc oxide enhances adhesion and provides an additional layer of corrosion resistance, preventing rust and degradation over time.
- This is particularly important for pipelines, industrial equipment, and structural metal components.
- Salt Air and Harsh Environments (e.g., Offshore Oil Rigs, Coastal Areas):
- If TC Ceramic is being applied in marine or coastal environments, where exposure to salt air and humidity is high, using a marine-grade zinc oxide primer or a corrosion-resistant epoxy primer is advised.
- Why? Salt exposure accelerates corrosion, and an extra protective layer beneath TC Ceramic helps prevent long-term metal deterioration.
When Is a Primer Not Required?
- For surfaces that are already painted, sealed, or properly prepared, a primer may not be necessary.
- TC Ceramic can be applied directly to cleaned and prepared surfaces without a primer in most standard applications.
- For non-metallic surfaces like concrete, masonry, or existing coatings, a primer is usually not required unless additional bonding strength is needed.
Final Recommendations:
- For bare metals: Use red zinc oxide primer.
- For salt-exposed environments: Use a marine-grade zinc oxide or corrosion-resistant epoxy primer.
- For prepared, painted, or non-metal surfaces: A primer is generally not needed unless specified for additional protection.
