KU5156 Next Generation Lens-to-Barrel Adhesive

KRYLEX® KU5156 is our next generation lens-to-barrel adhesive and has both excellent adhesion to LCP and high impact performance. Most importantly, this also enables high performance as the Compact Camera Module (CCM) industry moves from threaded LCP barrel assemblies to threadless LCP barrel assemblies. KU 5000 series focus on delivery high performance solutions for Compact Camera Modules. Depending on the specific bonding application, each adhesive will have very different performance requirements.

KRYLEX® Camera Module Assembly Adhesive range ensures:

  • High manufacturing throughput achieved through on-demand curing UV technology
  • Excellent optical performance related to low-shrinkage and low out gassing characteristics
  • RoHS-compliant, isocyanate free and solvent free
  • Excellent dispensability related to a high TI for high aspect ratio
  • Excellent mechanical performance leading to outstanding reliability and functionality

OPTICALLY CLEAR

KU5156 is optically clear with a high refractive index to meet strict optical requirements. Its low outgassing prevents possible fogging/clouding of lens assemblies.

THREADLESS BARREL ASSEMBLY

KU5156 enables high performance as the Compact Camera Module (CCM) industry moves from threaded LCP barrel assemblies to threadless LCP barrel assemblies.

LONG-TERM DURABILITY

KU5156 has excellent adhesion to Low Surface Energy (LSE) substrate.

KRYLEX® KU5000 Series Benefits:

  • Lens Bonding: KU5156 UV Curable acrylate adhesive is optically clear with a high refractive index to meet strict optical requirements.
  • Excellent adhesion to Low Surface Energy (LSE) substrate.
  • It provides high flexibility for superior impact resistance
  • The tack free cure surface ensures optical assemblies are not easily contaminated.
  • Its low outgassing prevents possible fogging/clouding of lens assemblies.
