Grip E751 | Annulus Void Filler | High Temperature Tolerant | Long Working Time

EXOTHERM TEMPERATURES

TEST DATA

Recommend Application Thickness is 6 mils on flat surface.

Recommended application is 231 cubic inches / gallon

CURE SCHEDULE

APPLICATION TEMPERATURE: 45- 110 degrees F

SURFACE PREPARATION

Clean out volumes as best as possible to remove loose debris, standing moisture, or anything else that would impede the adhesion of the product to the surface.

MIXING PROCEDURES

This material is a two-component product, premeasured to produce the desired kit size once part A and B are mixed. Depending on packaging, empty the entire containers of part A and part B into a mixing bucket large enough to accommodate the full mixed quantity. For large kits, a Jiffy type mixer with a high torque motor is recommended for proper blending. Mix for 1-2 minutes, taking care to reach all corners and walls to eliminate unmixed material.

**Unmixed material will never harden**

APPLICATION

GRIP E751 has a long pot life so material can be mixed and kept in container while applying.

• For large volumes, the full amount of material needed to fill the volume can be installed at once with no need for multiple smaller pours.
• On porous surfaces such as concrete, GRIP E751 will be absorbed into the concrete. Keep spreading material until no standing or “pooling” coating remains on the surface.
• When used with a cartridge, make sure a uniform mix is being achieved before using it to fill void spaces. The first few pumps of the applicator tool may dispel unevenly mixed material before the static mixer can properly mix A and B

CURING BEFORE SERVICE

GRIP E751 may be immersed in water 24 hours after application. It will cure to a hard film within about 14 hours and is suitable for light service at this time. If filling void spaces, after filling the annulus/void, the area can immediately be sealed and let to cure without

further intervention.

What is Grip E751 used for?

Grip E751 is designed to fill large annulus voids and structural gaps in industrial environments. It is commonly used where a flowable epoxy is needed to penetrate and fully fill deep or irregular spaces.

What makes Grip E751 effective for large void filling?

Grip E751 is formulated with a low viscosity, allowing it to flow easily into voids, and a low exotherm, which helps prevent overheating during curing in large pours. This combination makes it ideal for deep void fills and annulus applications.

Does Grip E751 have a long working time?

Yes, Grip E751 features a long working time (extended pot life 60 minutes @ 77F), allowing installers more time to place and adjust the material before it begins to cure. This is especially important for large-scale or complex void filling projects.

Can Grip E751 be used in high-temperature environments?

Grip E751 is high-temperature tolerant, making it suitable for use in industrial settings where elevated temperatures are present, such as near equipment bases or process areas.

What types of voids can Grip E751 fill?

Grip E751 is suitable for:

• Annulus voids
• Large structural voids
• Deep cavities in concrete or foundations
• Irregular or hard-to-reach gaps

Why is low exotherm important in a void filler?

Low exotherm means the product generates less heat during curing, which helps:

• Reduce risk of cracking
• Allow for larger volume pours
• Improve overall performance in deep void applications

How does Grip E751 flow into tight spaces?

Grip E751’s low viscosity formulation allows it to self-level and flow into tight or complex voids, ensuring complete coverage without leaving gaps.

Is Grip E751 suitable for industrial repair applications?

Yes, Grip E751 is specifically developed for industrial repair and maintenance, where durability, flowability, and working time are critical for successful void filling.

What are the benefits of a long working time epoxy for void filling?

A long working time allows for:

• Easier placement in large pours
• Better control during installation
• Reduced waste from premature curing
• Improved results in complex or multi-stage applications

Pro Tip

For best results when filling large annulus voids, pour Grip E751 in controlled lifts and allow the material to naturally flow and self-level rather than forcing it into place. This helps take full advantage of its low viscosity and low exotherm properties, ensuring more complete void filling and reducing the risk of trapped air or uneven curing—especially in deep or complex applications. Additionally, the Grip E751 can be mixed with blasting sand to create a flowable, high density epoxy mortar mixed that can be poured or pumped. Use a 2 gallon kit of epoxy resin, mix, add 2-3 gallons worth of blasting sand then  mix.
