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:

  1. 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.
  2. 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.
