Born2Bond™ Light Lock HV

LOW-ODOR, LIGHT-CURING CYANOACRYLATE

Manufacturer: Bostik

Package Size: Bottles: 20g, 500g

Shelf Life: 12 months

Product Overview

Born2Bond™ Light Lock HV is a low-odor, low-blooming, dual-curing (contact and light-curing) cyanoacrylate adhesive. It is designed for bonding applications that require fast fixturing, coating, or surface cure. The UV- and visible-light cure sensitivity allows rapid bonding through transparent parts and quick curing of light-exposed bulk or surface-coated areas, while the instant bonding capability ensures cure between opaque substrates (contact cure).

Key Features

  • Dual cure formulation: instant and photo-cure
  • Fixture time in 60 seconds (without light exposure)*
  • Can be cured with visible and UV-LED** light in <5 seconds
  • Long open time without activation
  • Dry-to-touch, tack-free surface cure
  • Cure-on-demand of excess material released from bondlines
  • Bonds, fills, reconstructs, and coats
  • Low odor, low blooming
  • Available in a range of viscosities: MV, HV, and Gel

Applications

  • Conformal coating
  • Encapsulation
  • Needle bonding
  • Perfume and liquor bottle metal bonding
  • Electronics assembly
  • Plastic-to-metal bonding for hearing aids
  • Glass-to-metal bonding for jewelry and watches
