RD-6™ Data Sheet

Polyguard's Pipeline Division has been active in the pipeline protective coating industry for more than 50 years. In addition to standard types of corrosion coatings, this division has designed, manufactured, and introduced a number of innovative underground pipeline coatings, which have become commercially accepted as standards for the industry.

RD-6™ pipeline corrosion coating is a system that allows cathodic protection currents to reach any disbonded area which occurs on the pipeline.

RD-6™ has been used on thousands of projects for over 19 years. Yet, to our knowledge, neither external corrosion nor SCC has been a problem under RD-6™. Why?

ADVANTAGE #1: RD-6™ is a non-shielding coating. This means that if the coating ever becomes disbonded, the pipeline is still protected because cathodic protection currents can reach the disbonded area. Once there, the current will raise the pH of the water underneath the disbonded area to 9 or higher – a level too high to support corrosion. Additionally, the geotextile fabric backing of RD-6™ does not shield cathodic protection currents. For more on Non-Shielding Coatings click here.

ADVANTAGE #2: RD-6™ is less likely to fail (to become disbonded) because:

• RD-6™ resists disbondment from the pipe, even if surface preparation is less than perfect. For more on Surface Preparation Quality Tolerence click here.

• RD-6™ is highly resistant to soil stress, a major cause of coating disbondment. For more on Resistance to Soil Stress click here.

• RD-6™ installs faster than almost any other coating, and requires no cure. For more on Fast Installation click here.

ADVANTAGE #3: RD-6™ is not a tape. North American pipeline operators have virtually banished solid film backed tapes and shrink sleeves. RD-6™ is quite different. For more on Tapes click here.

ADVANTAGE #4: RD-6™ has a long record of successful installations in the field. For more on Track Record click here.

The first installations of RD-6™ were in 1988. By 1992, the product was being widley used in North America. Today there are thousands of installations.
