Structural Bonding Solutions
Patvin Engineering is the leading supplier of Structural Bonding Solutions for EV Batteries with more than thirty years of experience.
Using adhesives for structural bonding methods help make a battery lightweight, while adding strength and rigidity. Typically, a one or two component epoxy is dispensed in a bead shape to bond two pieces of a battery pack together.
Precision and accuracy are important to proper bonding and efficient material use. Metering systems with strong material control and robust equipment to handle highly abrasive, medium to viscosity material is recommended.
Advantages of structural bonding:
- Helps make a battery lightweight
- Offers extra strength and rigidity to the battery pack
- Vibration and Fatigue Resistant

FAQs
Structural bonding refers to the process of using adhesives to join two or more substrates together. Unlike traditional methods like welding or riveting, structural bonding uses bonding solutions to create strong, lasting connections. It involves using structural adhesives that can bear loads and maintain the integrity of the joined surfaces. This technique is essential in industries where reliable bonding solutions are crucial. Structural bonding and adhesives ensure the integrity and strength of the assembled parts, making them vital for many applications.
Structural bonding has multiple types depending on their material and applications, such as:
- Epoxy Adhesives
- Acrylic Adhesives
- Polyurethane Adhesives
- Methyl Methacrylate Adhesives
- UV-Curable Adhesives
- Silicone Adhesives
- Cyanoacrylate Adhesives
Each bonding solution is designed for specific applications.
Benefits for use of Structural Bonding can be stated as:
- Strength: Structural adhesives can form bonds stronger than many mechanical fasteners.
- Weight Reduction: Using adhesives instead of metal fasteners can reduce the weight of structures.
- Versatility: Structural adhesives can bond a variety of materials, including metals, plastics, and composites.
- Stress Distribution: Adhesives spread stress over a larger area compared to traditional fasteners, reducing the risk of localized failure.
- Durability: Properly applied structural adhesives resist environmental factors such as temperature changes and chemicals, ensuring long-lasting bonds
