Born2Bond™ Light Lock MV

Dual cure (light and surface curing) cyanoacrylate

Manufacturer: Bostik

Package Size: Bottles: 20g, 500g

Shelf Life: 12 months

Product Overview

Born2Bond™ Light Lock MV is a low-odor, low-blooming, dual-curing cyanoacrylate adhesive that provides instant bonding through contact cure and rapid curing when exposed to UV or visible light. It is designed for fast fixturing, coating, and surface curing, ensuring a dry-to-touch, tack-free surface. This adhesive enables cure-on-demand of excess material outside the bondline and is available in different viscosities, including Medium Viscosity (MV), High Viscosity (HV), and Gel.

Applications

Born2Bond™ Light Lock MV is ideal for precision bonding and assembly in various industries, including:

  • Electronics assembly
  • Plastic-to-metal bonding (e.g., hearing aids, jewelry, watches)
  • Needle bonding
  • Perfume and liquor bottle metal bonding
  • Glass-to-metal bonding
  • Conformal coating and encapsulation
