Powercrete J: The Premier Two-Part Epoxy for Field Joint Protection

When it comes to protecting pipeline weld joints, not all coatings are created equal. In demanding applications like directional drills and road bores, the stakes are even higher. Abrasion resistance, adhesion, and long-term corrosion protection aren’t optional — they’re essential.

That’s where Powercrete J stands apart.  It was built for Directional Drills and Road Bores

In HDD (horizontal directional drilling) and road bore installations, pipelines are subjected to:

• Extreme abrasion during pullback

• High soil stress and friction

• Challenging environmental conditions

Powercrete J has earned its reputation as a premier two-part epoxy field joint coating specifically because it performs under these exact conditions. Its abrasion resistance and bond strength make it a go-to solution when the weld joint cannot be the weak link.

When you’re pulling thousands of feet through a bore, the last thing you want is coating failure at the weld.

Here’s something many people don’t realize:  Powercrete J isn’t just for HDD and road bores.

It’s also an excellent solution for standard field joints. Even in conventional installations, weld areas deserve the same level of protection as the factory-applied coating. Using a high-performance epoxy ensures continuity of corrosion protection across the entire pipeline.

If your pipe has been factory coated with Powercrete-DD, the recommendation is simple:

Pair it with Powercrete J for the field joints.

Powercrete-DD is widely recognized as one of the best abrasion resistant overcoats (ARO) on the market. And if your pipeline deserves that level of factory protection, it only makes sense to extend that same standard to the weld joints.

Powercrete J is available as a standard in:

• 2-pound kits

• 4-pound kits

Custom kit sizes are also available upon request, giving contractors flexibility depending on pipe diameter and project scope.

Want to See It for Yourself?

If you’re in the United States and would like to get your hands on a sample, let’s talk. There’s no substitute for seeing how a product handles in real-world conditions.

When it comes to protecting weld joints — whether in a challenging directional drill or a standard pipeline installation — Powercrete J delivers performance you can trust.

Because your pipeline deserves more than “good enough.”

Powercrete R65 / F1

 

Powercrete R65/F1: Fast-Cure Performance, Long-Term Protection

When it comes to field-applied corrosion prevention coatings, the demands are simple—but not easy. Crews need a material that applies cleanly, cures quickly, and delivers true long-term protection in the harsh environments where pipelines live their entire lives. Powercrete R65/F1 has become a trusted industry standard because it checks every one of those boxes with consistency.

A Fast-Cure Epoxy That Keeps Projects Moving

Downtime is expensive. Waiting on slow-curing coatings can bottleneck an entire jobsite—especially when tie-ins or holiday repairs need to happen immediately. Powercrete R65/F1 is formulated as a fast-cure epoxy, allowing crews to move quickly, get coatings inspected sooner, and keep construction schedules on track. That fast cure does not come at the expense of performance. When fully cured, R65/F1 delivers a tough, high-build, high-adhesion barrier that protects pipelines from corrosion for decades.

Packaging Options Designed for Real Jobsite Needs

One of the most appreciated advantages of Powercrete R65/F1 is the flexibility in packaging. Different projects demand different volumes, and wasted material is wasted money. That’s why R65/F1 is available in a range of kit sizes, including:

• 1 lb kits – perfect for small jobs, cutbacks, or short sections of pipe

• 2 lb kits – a balanced size for typical daily field use

• 4 lb kits – ideal for spreads with higher daily production

• Custom kit sizes – tailored for unique applications, specialty work, or large-volume requirements

This scalability means contractors only use what they need—nothing more, nothing less.

Field Repair Options That Solve Real Problems

Coating damage happens. Weather, handling, equipment, and transport all take their toll. Powercrete R65/F1 offers smart solutions that allow crews to respond quickly without breaking stride.

50 ml Repair Cartridges

These small-format cartridges are designed for quick, precise repairs to existing epoxy coatings or fusion bonded epoxy (FBE). They’re easy to deploy, minimize waste, and provide a high-performance repair that blends seamlessly with the surrounding coating.

400 ml Spray Cartridges

For wider areas, irregular surfaces, or repair zones that require a more uniform finish, the 400 ml spray cartridge provides speed, coverage, and consistency. Crews simply snap the cartridge into an applicator and spray—no mixing by hand, no guesswork, and no lost time.

Reliable Corrosion Protection Backed by Field History

Powercrete R65/F1 has earned its reputation over years of successful field performance. It bonds strongly to steel and adheres exceptionally well to prepared surfaces. Once cured, it forms a durable, high-build layer that resists impact, abrasion, soil stress, and moisture—exactly what’s required for long-term corrosion prevention on buried pipelines and field joints.

Built for Efficiency. Built for Durability. Built for the Field.

Every pipeline project is different, but the need for reliable protection never changes. Powercrete R65/F1 brings together fast cure times, flexible packaging options, and proven corrosion resistance—making it a practical solution for contractors, inspectors, and asset owners alike.

Powercrete R65/F1 Cold Weather Application

 

Powercrete R65/F1: Epoxy Coating for Cold Weather Pipeline Protection

 is a high-performance, fast-curing epoxy coating specifically engineered for the protection of steel pipelines, including applications in cold weather environments. Its unique formulation and application versatility make it a preferred choice for both new construction and rehabilitation projects where rapid turnaround and reliable corrosion protection are critical.

• 
  Powercrete R65/F1 is recognized as the go-to fast-cure epoxy within the Powercrete product line for use in the coldest temperatures. Its rapid cure profile enables efficient production and quick backfilling, even in challenging weather conditions

• 
  The coating is solvent-free, containing no volatile organic compounds (VOCs), making it environmentally friendly and safe for use in confined or sensitive areas

• 
  Powercrete R65/F1 can achieve a dry film thickness (DFT) of up to 40 mils (1000 microns) or more in a single multi-pass application, ensuring robust protection against corrosion and mechanical damage

• Versatile Application Methods

• The epoxy can be applied by hand (brush, roller, or trowel) or by spray using conventional plural component equipment, providing flexibility for field joints, girth welds, fittings, and repairs

• 
  It bonds strongly to both abrasive-blasted steel and fusion bonded epoxy (FBE) coated pipes, offering outstanding resistance to cathodic disbondment, abrasion, and impact

• 
  Thanks to its quick cure time, Powercrete R65/F1 allows for almost immediate backfilling after application, which is especially advantageous in cold climates where project schedules are often tight

Powercrete R65/F1 is specifically formulated for cold weather use. Its fast cure chemistry ensures that the coating hardens efficiently even at low ambient temperatures, minimizing delays associated with slow curing times common to many epoxies in cold conditions. This makes it ideal for pipeline projects in winter or in regions with consistently low temperatures.

• Mainline and field pipeline joints

• Girth welds and field joints

• Pipe bends, fittings, and valves

• Rehabilitation of existing pipelines and touch-up of damaged coatings

• Buried tanks and other steel structures requiring corrosion protection

• : The substrate must be clean, dry, and free from oil, grease, and
  contaminants. Abrasive blasting or mechanical cleaning is recommended to achieve the necessary surface profile.

• : Standard 2:1 mixing ratio for bulk applications; 1:1 ratio for cartridges.

• : Can be hand-applied or spray-applied, depending on project requirements and available equipment76.

• : The rapid cure time allows for handling and backfilling soon after application, even in cold weather.

Powercrete R65/F1 meets industry standards such as EN 10289 and CSA Z245.30 for pipeline coatings, ensuring compliance with rigorous quality and performance requirements3.
