PBT – Aluminium Keyboard Housing

DELO’s PHOTOBOND adhesives are specifically designed to overcome the challenges faced when bonding aluminium to PBT (polybutylene terephthalate) in keyboard housings.

Adhesives Plastic Applications

What do PBT – Aluminium Keyboard Housing Adhesives do?

In an application like this where there is a mismatch in the coefficients of thermal expansion (CTE) an adhesive offering high flexibility is required to overcome this. DELO PHOTOBOND adhesives offer this along fast curing making it possible to manufacture these parts in high volumes.

DELO PHOTOBOND is a one-part, light-cured adhesive with an elongation > 100% (in this case, as high as 300%), that compensates for the stresses induced when the bonded parts are exposed to temperature extremes and expand / contract at different rates.

DELO PHOTOBOND Adhesives Key Features

  • Rapid curing with UV or visible light
  • Curable through translucent plastics that filter UV
  • Provides invisible, high-strength bonds
  • One-part in a range of low to high viscosities

Why DELO PHOTOBOND UV Adhesive?

  • Curable Through Translucent Plastics: Works even when UV light is partially filtered by the substrate.
  • Flexible Bond Line: With elongation values up to 300%, the adhesive compensates for thermal expansion differences between aluminium and PBT, preventing stress fractures and delamination.
  • One-Part, Light-Cured: Simplifies processing and eliminates the need for mixing or heat curing.
  • Fast Curing: Enables rapid cycle times, ideal for automated production lines.
  • Invisible Bonding: Cures clear and clean, preserving the aesthetic of visible components.

Application Benefits

  • High Strength: Provides durable, long-lasting bonds under mechanical and thermal stress.
  • Process Efficiency: Supports high-throughput manufacturing with minimal waste.
  • Versatile Viscosity Options: Available in a range of flow characteristics to suit different dispensing methods.

Use Cases

  • Custom keyboard and interface assemblies
  • Consumer electronics housings
  • Automotive interior components
  • Industrial control panels
