GorillaPro® EP3 is a two-component, amber-colored epoxy adhesive that cures at room temperature and sets extremely fast. It is commonly used for repairs, fixturing, and bonding to various materials such as plastics, metal, ceramics, concrete, wood, and stone. GorillaPro® EP3 is an excellent general-purpose adhesive that can cure at temperatures as low as -18 °C (0 °F). The adhesive is conveniently packaged in a 3.5 gm DOUBLE/BUBBLE® packet.

Product Features

Permanently Bond Almost Anything
Epoxy adhesives are higher strength solutions and prevent surfaces from moving. Urethane adhesives retain flexibility and are better suited for structures that contract or expand with temperature. These products offer good chemical resistance, which reduces repeated or nagging repair cycles. GorillaPro epoxies and urethanes can permanently bond almost anything, including engineered thermoplastics, thermosets, nylon, composites, e-coat, and metals.

  • Strong, rigid bonding
  • Excellent resistance to heat and chemicals
  • Withstands constant weight or force over time

High-Performance MRO Solutions
Proactive maintenance can help prevent costly unplanned downtime. It’s a challenge keeping up with maintenance activities while keeping teams trained, equipment operating, and driving productivity. With a full complement of maintenance adhesives, repair epoxies, lubricants, and sealants, GorillaPro products can repair and improve the reliability of almost any piece of equipment or machinery.

Applications & Uses

Cure Method
Typical Uses

This Extra Fast-Setting Epoxy can be used to repair tools, auto parts, electrical and electronic components, furniture and other applications that require a fast-setting adhesive.

Curing Process:
The cure schedule is dependent upon the temperature. The recommended cure schedule will vary with the desired properties.

Application Instruction


The surface must be clean and dry before application. Remove all chemicals, dirt wax, and oil.
Fold the DOUBLE/BUBBLE® package along the center seal, snip the end, squeeze out the contents, mix thoroughly and apply. These materials are intended for industrial use only.
GorillaPro® EP3 - Application Instruction

Avoid contamination with oxidized metals (such as copper, brass, or mild steel), and rust or other metal oxides. The stability of the product is greatly reduced by materials such as strong acids or bases, sulfur compounds, amines, or reducing agents of any type. Surfaces to be bonded must be clean, dry and free from grease, oil, wax, weak oxide films, and other contaminants.

Packaging & Availability

Packaging Information

The DOUBLE/BUBBLE® package is a handy, dual-pouch, one-shot, job-size packaging concept. It reduces the waste typically associated with the use of larger quantities of two-component adhesives. This unique packaging ensures that DOUBLE/BUBBLE(r) adhesives are always factory fresh and accurately portioned for optimum adhesive performance.

Storage & Handling

Shelf Life
