How to Diagnose Adhesive Bond Failure Before Changing the Glue?
When an adhesive joint fails, changing to a stronger adhesive is not always the correct first step. Buyers and production engineers should first determine where the failure occurred, under what conditions it occurred, and whether the problem came from the adhesive, substrate, surface preparation, joint design, or curing process. ASTM D1002 itself warns that adhesive […]
How to Qualify an Industrial Adhesive Supplier Before Bulk Ordering?
Choosing an industrial adhesive supplier should not start with the lowest price or a catalog product name. For production buyers, the more reliable approach is to qualify the supplier through quality-system evidence, application samples, test data, batch consistency, technical support, and supply response before placing a bulk order. For higher-risk applications such as automotive, electronics, […]
Electronics Potting & Encapsulation Adhesive: Epoxy vs PU vs Silicone Selection Guide
AI Overview: Protecting a PCB is a choice between conformal coating (a thin 25–200 µm film that follows board contours) and potting / encapsulation (flooding the assembly in 1–10 mm of compound for full sealing). The compound decision — epoxy, polyurethane or silicone — cannot be undone cheaply. Epoxy gives maximum rigidity, dielectric strength and […]
Cold Chain & Refrigerated Transport Panel Adhesive: 2K PU Structural Bonding Guide
AI Overview: A refrigerated panel is a sandwich: two facings (steel, aluminium or FRP) bonded to an insulating foam core (PU, PIR or XPS). The foam controls heat transfer, but the adhesive holds the composite together for 10–15 years across freeze/thaw cycles, road vibration and washdown. Failures start as delamination at the skin-to-core bond line, […]
Flame-Retardant Bonding for Eco Fire Doors, Steel-Structure Enclosures and Curtain Walls
Fire safety is no longer a finishing touch — it is a code-driven specification written into the building from day one. Eco fire doors, steel-structure enclosures, and building curtain walls must satisfy flammability and smoke-toxicity classes that vary by market (GB 8624 in China, EN 13501-1 in Europe, ASTM E84/E119 and BS 476 elsewhere). The […]
Metal Sandwich and Honeycomb Panel Bonding for EV Battery Enclosures and Energy Storage Cabinets
As electric vehicles and grid-scale storage move from prototype to mass production, the enclosure that protects the battery pack has become a structural and thermal-engineering problem in its own right. Traditional welded or mechanically fastened metal boxes are heavy, create local stress concentrations, and slow assembly. A growing number of OEMs and pack integrators are […]
