PERMABOND® UV643 is a thixotropic, extremely fast UV-curable acrylic adhesive developed for the fast bonding of many rigid plastics, also in combination with metals. It cures tack-free and provides excellent performance on several thermoplastics including polycarbonate, PMMA PETG, PET, ABS, and rigid PVC. It also provides high durability when exposed to hot/wet conditions (i.e. tested at +85°C/85% RH).

FEATURES:

  • Excellent strength on PC, PVC, and other rigid plastics
  • Tack-free surface cure
  • Very quick cure at wavelengths from 365 to 420 nm, good on stabilized plastics
  • Exceptional resistance to warm and humid conditions
  • Excellent resistance to thermal cycles on plastic assemblies
  • Resists yellowing
