GorillaPro® PU5 is a two-component, beige-colored structural urethane adhesive that sets extremely fast. It is commonly used for repairing and bonding urethane parts, thermoplastics, laminated surfaces, metal, leather, glass, and stone. The adhesive is rigid, impact-resistant, and exhibits good peel and shear strength. GorillaPro® PU5 offers an excellent combination of shear strength, peel strength, and impact resistance. It is conveniently packaged in a DOUBLE/BUBBLE® 3.5 gm 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

Compatible Substrates & Surfaces
Application Method

Recommended Substrates
Engineered thermoplastics, SMC, laminated surfaces and repair of reaction injection molded parts, metal, carbon steel, stainless steel, aluminum, tin, plastic, epoxy, polyester, phenolic, urethane, stone, glass, ceramic, leather.

Typical Uses
Fast Setting Urethane can be used to repair urethane reaction injection molded parts. It is recommended for repair of rubber hoses, conveyor belts, flexible electrical connections, and bonding refrigeration and air-conditioning equipment.

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

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.

GorillaPro® PU5 - Application Method

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.
