8805 Acrylic AB Glue

8805 is a two-part 10:1 MMA acrylic structural adhesive, light blue after mixing, initial cure within 5.6 minutes at 25℃ with shear strength up to 20MPa. It is specially developed for structural bonding of mobile phones, laptops, tablets and other 3C consumer electronics housings. 
This primer-free adhesive bonds dissimilar substrates including metal, PC, ABS, zinc alloy and stainless steel directly. Toughened formula delivers outstanding impact, drop and vibration resistance. Fully cured glue passes thermal shock, temperature cycling and humidity aging reliability tests, perfectly suitable for mass automatic assembly lines. The light blue glue layer is visible for easy inspection to reduce defective products caused by missing glue.

Electronic Equipment Manufacturing Field (Core Scenario): Bonding of smartphone middle frame and screen, fixing of PCB components, bonding of camera modules and lenses, battery pack packaging, splicing of smart wearable devices (watch/band) casings, sealing of router/switch casings, fixing of power bank batteries, bonding of earphone sound units and casings, reinforcement of tablet computer middle frame, fixing of drone motors and casings; Industrial Manufacturing Field: Bonding and repair of auto parts (replacing welding to avoid part deformation), splicing of hardware products (such as integrated bonding of stainless steel and iron products, strength comparable to welding), assembly of mechanical equipment (replacing riveting to improve assembly efficiency); 

Building Decoration Field: Sealing of door and window glass, fixing of decorative materials, repair of wall cracks (high bonding strength can ensure the repaired part is firm for a long time and not easy to crack again); Crafts Field: Bonding and repair of ceramic, glass, resin and wooden crafts (firm bonding, no trace after curing, no impact on the beauty of the product); Daily Maintenance Field: Emergency repair of household items (ceramic, plastic, wood, metal) (high bonding strength can achieve long-term firm repair without frequent rework); Special Scenarios: Bonding of outdoor equipment, short-term underwater bonding, bonding in low-temperature environment (above 5℃), suitable for multi-scenario high-strength bonding needs, reducing construction difficulty and improving construction quality.
