Polyguard Products Non-Shielding Coatings, Anti-Corrosion Gels and Vapor Barriers
Polyguard Products has been manufacturing underground pipeline coating systems for buried pipelines since 1950. The specialty product, the RD-6 coating system, proven in the North American market since 1988, is the only proven field-applied coating that is non-shielding to cathodic protection currents in case of a disbondment from the substrate.
The RD-6 has been declared Mobil Asset Services’ number one rehabilitation and maintenance system in a public study versus all other contemporary existing field technologies present in the market.
Polyguard Products prides itself on innovative technologies that differentiate it from mass market products.
Non-shielding coating system for underground pipelines
The RD-6 coating system is a uniquely designed coating system. The product has been proven in over two decades of applications to not impede cathodic currents in case of a disbond and if adequate cathodic protection currents are available. It has been used in thousands of applications.
Additionally, the product offers superior soil stress resistance compared with other traditional tape systems, thanks to the polypropylene backing and the superior adhesion to substrate that the compound has. The ability to resist soil stress is vital to a coating system’s performance, thus the RD-6 offers a much better resistance to soil stress as well as the capacity to allow cathodic current flow in case of a disbond. The compound is also self-healing.
Reactive gels for corrosion under insulation
Polyguard manufactures a distinct technology for corrosion under insulation (CUI). Used in the US for decades and specified by the US Navy for use in every active ship with watertight doors since the 1990s, this technology highly outperforms traditional paints in crevice environments. Using unique mineralization technology coupled with more conventional corrosion inhibitors and buffering elements, the reactive gels provide superior corrosion protection and are an excellent option for intervention and rehabilitation of corroded metals.
The reactive gels’ performance is almost completely independent of surface preparation and profile; only large-scaled corrosion needs be removed before simple hand, brush or spray application. No primers are required, and there are no volatile organic chemicals or other environmental concerns.
The systemic cost of applying the gel is often cheaper than traditional paints, and always much cheaper than thermal spray aluminum in-situ. It is also drastically simpler and safer than thermal spray aluminum.
The reactive gels are used for CUI, valves, tank bottoms / chimes and oil well heads as well as military and other industrial uses. They are protected by multiple American and other international patents.
Insulation vapor barriers for refinery and LNG plants
Polyguard also manufactures a range of insulation vapor barriers, including an innovative alternative to metal jacketing called Alumaguard. The vapor barriers have been installed on numerous refinery and LNG plants worldwide, and Alumaguard has replaced a large percentage of the traditional metal jacketing in North America for over ten years.
Alumaguard is competitively priced compared with metals, installs in a fraction of the time, does not require skilled labor and is fully waterproof, in addition to being a self-healing vapor barrier that doesn’t require fasteners.
