Guide to Choosing the Best Adhesive for Pelican Cases

Imagine your custom-fitted PELICAN™ protective case with securely mounted internal components, perfectly safeguarding your valuable equipment against even the harshest environmental conditions. This level of protection, however, depends entirely on selecting the appropriate adhesive. This article examines the critical considerations for bonding PELICAN™ cases and provides professional adhesive recommendations to ensure your customization remains reliable.

Renowned for their exceptional protective qualities, PELICAN™ cases serve diverse industries worldwide. Customization frequently requires bonding various accessories like Peli Quick™ Mounts inside the case. However, the specialized material composition of PELICAN™ cases makes adhesive selection particularly crucial. Improper adhesive choices may result in weak bonds or even case damage.

Manufacturers typically produce PELICAN™ cases through injection molding of polypropylene (PP). This thermoplastic polymer demonstrates outstanding chemical resistance and impact absorption. Polypropylene's low surface energy, however, presents bonding difficulties. For optimal results, professionals recommend using adhesives specifically formulated for polypropylene compatibility.

3M Scotch-Weld™ DP8005 and DP8010 represent specialized two-component epoxy structural adhesives engineered for bonding low-surface-energy plastics. These formulations achieve strong bonds on polypropylene and similar materials without requiring surface treatments or activators. Both adhesives demonstrate exceptional resistance to water, humidity, and chemical corrosion, meeting the demanding environmental requirements of PELICAN™ case applications.

While both adhesives suit PELICAN™ case bonding, key differences influence selection. DP8005 offers broader material compatibility, including aluminum and glass bonding. DP8010 specializes in TPO and pretreated metal applications. The latter features slower curing with extended working time, making it preferable for applications requiring precise positioning.

For optimal bonding performance, consult this compatibility guide:

• Polypropylene (PP)
• Polyethylene (PE) (HDPE/LDPE)
• TPO (DP8010 only)

• Fiber-reinforced plastic (FRP)
• Pretreated metals (DP8010 only)
• Polycarbonate
• Wood
• Aluminum (DP8005 only)
• Glass
• Thermoplastic elastomers (TPE)
• Rigid PVC
• ABS
• Acrylic (PMMA)
• Polystyrene
• Concrete

• PTFE (Teflon)
• Silicone surfaces
• Mold release agents
• Polyimide
• Nylon

• These ABS plastic components bond less effectively with polypropylene than polypropylene-to-polypropylene connections. However, adequate curing time (24 hours) typically produces satisfactory results.
• For enhanced shear strength, consider mechanical fasteners like bolts and nuts. Note that this compromises case integrity and may necessitate additional waterproofing measures such as silicone or rubber gaskets.

1. Surface Preparation: While DP8005/DP8010 require no special treatment, proper cleaning remains essential. Wipe bonding surfaces with isopropyl alcohol or suitable cleaner to remove oils, dust, and contaminants. Ensure complete dryness before proceeding.
2. Adhesive Mixing: Combine components A and B according to manufacturer specifications. Thorough mixing ensures optimal performance.
3. Application: Apply mixed adhesive evenly across bonding surfaces. Avoid excessive application to prevent overflow. For Peli Quick™ Mounts, coat the entire base surface.
4. Bonding: Position components accurately and apply appropriate pressure. Use clamps or fixtures to maintain alignment during curing.
5. Curing: Allow adhesive to cure completely per the schedule. Avoid disturbing bonded components during this period.
6. Inspection: Verify bond integrity after curing. Address any deficiencies (weak bonds, cracks) with corrective measures.

• Wear protective gloves and eyewear during adhesive handling
• Conduct bonding operations in well-ventilated areas
• For skin or eye contact, rinse immediately with water and seek medical attention
• Store adhesives according to manufacturer recommendations, avoiding direct sunlight and high temperatures

As mentioned, mechanical fasteners can enhance shear strength when necessary. However, this approach compromises waterproof integrity. Mitigation strategies include:

• Silicone/rubber gaskets for bolt hole sealing
• Waterproof tape or coatings for additional protection

Proper adhesive selection forms the foundation of successful PELICAN™ case customization. 3M Scotch-Weld™ DP8005 and DP8010 provide reliable, durable bonding solutions. By following these guidelines, professionals can ensure their customized configurations deliver maximum equipment protection.
