The Original EPO Dynaweight

The Original EPO Dynaweight

Proven epoxy dynamic balancing compound for motors, fans, blowers, and other rotating equipment.

The Original EPO Dynaweight is a dense, two-component epoxy balancing compound developed specifically for correcting imbalance in rotating parts.

Used for decades by OEM manufacturers, motor repair shops, and industrial maintenance facilities, EPO Dynaweight provides a simple and effective alternative to traditional balancing weights. The material can be applied exactly where weight is needed, helping eliminate many of the location and attachment problems associated with conventional balancing methods.

EPO Dynaweight is well suited for:

• Electric motor rotors and armatures
• Fans and blowers
• Generators
• Rollers
• Printing and coating equipment
• Computer and precision spindles
• Fractional-horsepower through large industrial motors
• Other rotating components requiring dynamic balance
• drone motors and rotor blades

Easier Dynamic Balancing

EPO Dynaweight allows balancing weight to be added directly to the rotating component, reducing the need for drilling, welding or attaching conventional weights.

The compound is non-conductive, making it particularly useful around electrical components where metallic balancing methods may create additional concerns.

Its long working time also allows the technician to apply, test and adjust the amount and location of the balancing compound before the material hardens.

Working Time and Cure

Dynamis Epoxy uses 75°F as its standard room-temperature testing condition.

At 75°F:

• Working time: approximately 2–2½ hours
• Initial cure / hard set: approximately 12 hours

EPO Dynaweight may also be accelerated with heat when a faster return to service is required.

Warmer temperatures will shorten working and cure times, while colder temperatures will extend them

Mixing & Application Help

EPO Dynaweight is hand mixed using equal parts Part A and Part B by volume. Knead the two components together until the material becomes a completely uniform medium gray with no streaks or unmixed pockets. The mixing endpoint is uniform color, not a fixed mixing time.

If the material is unusually stiff or difficult to mix, check the material temperature before proceeding. EPO Dynaweight should be stored between 70°F and 85°F and protected from freezing. Cold material can become firmer and may require additional time to return to a workable temperature.

Proven Industrial Performance

EPO Dynaweight has been used for decades to balance rotating equipment in manufacturing, motor repair and industrial applications.

Its combination of density, adhesion, electrical non-conductivity and ease of placement makes it a versatile solution for both production balancing and repair work.
