What Makes RD-6 a Proven Choice for Corrosion Protection?

Polyguard RD-6 is a non-shielding, anti-corrosion coating system engineered to safeguard buried and submerged pipelines from corrosion. Its polymer-modified coating layer, bonded to a tightly woven polypropylene geotextile fabric, provides excellent durability, high tensile strength, and low elongation — ensuring long-term protection without compromising cathodic protection efficiency.

How Does the RD-6 System Work?

The RD-6 Coating System combines three layers of defense:

  • Liquid Adhesive Primer for superior surface bonding.

  • Geotextile-Backed RD-6 Coating for corrosion resistance and flexibility.

  • SP-6 Outerwrap & UV Overcoat for added protection and UV stability above ground.

This system is ideal for buried and submerged pipelines, girth welds, and rehabilitation projects, with compatibility for operations up to 145°F (63°C). For higher temperatures, RD-6 HT is recommended.

Why Choose RD-6?

  • Non-shielding design — prevents corrosion under disbonded coating.

  • Ease of installation — supplied in rolls and applied with a Polyguard-approved machine.

  • Proven field performance — widely trusted for long-term corrosion control.

Choose PetroMarys for certified Polyguard RD-6 solutions, ensuring reliable protection, extended service life, and cost-efficient performance for your critical pipeline assets.

PetroMarys ProductsRD-6 HTProtection

High-performance gaskets designed to meet the demanding needs of the oil & gas, marine, and industrial sectors.

PetroMarys supplies Polyguard RD-6 HT®, a non-shielding, anti-corrosion coating for buried, submerged, and new pipeline applications.
Reinforced with polypropylene geotextile fabric, it offers high strength, low elongation, and long-term corrosion protection.
For above-ground use, apply RD-6 UVO for added UV resistance.

Features & Benefits:

  • Non-shielding design — allows cathodic protection currents to reach the pipe surface.

  • High-temperature service — suitable for pipelines up to 190°F (88°C).

  • Superior cathodic disbondment resistance, even with minimal surface prep.

  • Strong geotextile backing — resists soil stress and maintains coating integrity.

  • Fast and easy to apply — backfill immediately after coating.

  • Visco-elastic flexibility — accommodates thermal expansion and contraction.

  • Excellent adhesion — woven fabric promotes uniform bonding at overlaps.

  • Water vapor resistant — ensures consistent protection in challenging conditions.
