Case Study

Application: Repairing Electrical Components Bonded to Train Doors with ARALDITE® 2051 Adhesive

Speed up assembly time with a short curing time and the ability to bond on wet surfaces. 

The Challenge
Bonding small electrical components to potentially wet train door panels.

The Solution

ARALDITE® 2051 adhesive was chosen for this repair application due to its good adhesion to various metals and plastics without surface preparation – even when the surface is wet.

Simple application with cartridges, and a fast cure enabled an efficient process with reliable results.

Case Study

Application: Bonding Outdoor Rail Infrastructure with ARALDITE® 2051 Adhesive

Keep outdoor maintenance operations going, even in cold, damp weather. 

The Challenge

The Solution

With strong adhesion on composites and metals combined with a high lap shear strength, ARALDITE® 2051 adhesive is perfectly suited to bond small interior parts.

Limited surface preparation and a short curing time help decrease cycle times, leading to increased production throughput.

Case Study

Application: Bonding Inside Blade Add-Ons with ARALDITE® 2051 Adhesive

Reduce maintenance costs by up to 70% with highly-durable bonds. 

The Challenge

Bonding add-ons such as sensors on wind blade composite internal structure. 

The Solution

Approved for this specialized application, the versatile ARALDITE® 2051 adhesive can also be used in other wind blade applications, thereby reducing your inventory and complexity.

Thanks to its reliable, long-term bonding capability, this adhesive can lead to a 70% reduction in maintenance costs.

Case Study

Application: Bonding and Repair at Sea with ARALDITE® 2051 Adhesive

Bond fast and on-the-go in harsh and humid conditions and reduce asset downtime by up to 50%.

The Challenge

Repairing and finishing small to medium-sized components after a ship has left the controlled conditions of the shipyard and is exposed to a wet, cold environment.

The Solution

Packed in handy and safe cartridges, ARALDITE® 2051 adhesive is a valuable tool to keep onboard. This adhesive will help you speed up repairs and get back to operations quickly, reducing your downtime by up to 50%.

With ARALDITE® 2051 adhesive, you can bond any kind of material outdoors – and even underwater. This non-sagging adhesive is easily applied vertically and overhead for both small fixes and major repairs.
