Technical FAQ: Expert Insights on Orange PU Glue & Related Adhesives

Expert FAQ

  1. Q1: What is the main chemical difference between orange pu glue and black pu glue?
    A: Orange PU glue and black PU glue share a polyurethane backbone but differ in colorant masterbatch (organic oranges vs. carbon black) and stabilizing additives, affecting heat resistance and visual performance.
  2. Q2: How to select optimal viscosity for hot melt sticks in electronics assembly?
    A: Choose sticks (e.g., 2000–3300 mPa·s @180°C) for capillary control—lower viscosity for fine PCBs, higher for cable harnesses. Always pre-test bonding time to match equipment speed.
  3. Q3: What international standards are applied for orange pu glue in the filtration industry?
    A: ISO 9001:2015 for QC, FDA CFR 21 for food contact, ANSI/NSF for potable water, REACH/RoHS for environmental safety.
  4. Q4: What key parameters affect the durability of orange pu glue in metal cap bonding?
    A: Service temperature, humidity, chemical inhibitor presence, and curing profile (controlled by process). Adherence to ISO 527 shear tests is crucial for qualification.
  5. Q5: What is the difference between AB glue and hot melt adhesive for industrial assembly?
    A: AB glue is a two-part epoxy with higher heat/chemical resistance and slower cure, while hot melt adhesive is one-part fast-bonding, best for rapid-line assembling.
  6. Q6: How do you verify if your batch of PU glue is compliant?
    A: Check for third-party certifications (ISO, RoHS, FDA), in-batch test data (shear, viscosity, aging), and ensure batch traceability in the Certificate of Analysis.
  7. Q7: What is the proper storage for orange pu glue?
    A: Store at 15–25°C, in airtight and light-blocking container111s, avoid moisture or heat exposure. Use within 12 months for guaranteed optimal performance.
