Euclid E3 HCR

Euclid E3 HCR is a precision-formulated, three-component epoxy grout built for critical installations in chemically aggressive environments. It features a novolac epoxy resin base that delivers superior chemical resistance—far beyond what standard epoxy systems provide. As a result, it performs consistently when exposed to concentrated acids, caustics, and a broad range of industrial solvents.

In addition, Euclid incorporates its proprietary DL Technology aggregate to improve safety and application efficiency. This blend minimizes airborne dust during mixing and enhances flow, making it easier to place under equipment baseplates and within containment structures.

After post-cure, E3 HCR achieves compressive strengths above 20,000 psi. Moreover, it holds its shape under continuous mechanical and thermal loading. That combination of strength and stability makes it a reliable solution for pump bases, process equipment, secondary containment, and other demanding chemical environments.

Key Features of E3 HCR

• Exceptional Chemical Resistance
  Designed to perform in highly aggressive chemical environments including concentrated sulfuric, hydrochloric, and sodium hydroxide.
• Ultra-High Strength
  Reaches compressive strengths up to 20,000 psi with post-curing, allowing for long-term durability under heavy static or dynamic loads.
• Outstanding Bearing Support
  Delivers >95% Effective Bearing Area (EBA) to ensure positive load transfer and minimal movement under stress.
• Low Creep and High Dimensional Stability
  Maintains shape and load support over time—even under high temperatures and loads.
• DL Technology Aggregate
  Reduces airborne dust during mixing, improving jobsite cleanliness and worker safety.
• Fast Return to Service
  Achieves high early strengths for rapid equipment turnaround and minimized downtime.

Recommended Uses for E3 HCR

Euclid E3 HCR is built for equipment grouting in environments where chemical attack is severe. This includes facilities with exposure to acids, fuels, caustics, and solvents. It’s a reliable choice for applications requiring a non-shrink, non-corrosive, highly durable grout.

Ideal For:

• Chemical processing facilities
• Pump and compressor baseplates
• Secondary containment areas
• Wastewater treatment plants
• Refineries and tank farms
• Power generation and paper mills

Frequently Asked Questions

What types of chemicals can E3 HCR resist?
E3 HCR offers broad chemical resistance. It withstands exposure to sulfuric acid, hydrochloric acid, sodium hydroxide, gasoline, diesel, MEK, and many other industrial substances.

How thick can it be applied?
You can apply E3 HCR in lifts from 1 inch to 6 inches, depending on the requirements of the project. This flexibility makes it suitable for a variety of placements.

What is the working time after mixing?
At 73°F (23°C), working time is approximately 34 minutes. This window allows enough time to properly place and finish the material.

Does E3 HCR require special curing?
No. It cures effectively in the field without special procedures. Although post-curing is used for lab testing, it isn’t necessary for typical jobsite installations.

Is it safe for use near sensitive electronic or cleanroom equipment?
Not exactly. E3 HCR is built for harsh industrial environments, not cleanrooms. For those conditions, consider a product specifically made for sensitive applications.

What is the shelf life?
When stored properly in its original, sealed packaging, it remains usable for 12 months.
