1. Product Overview

LOCTITE ABLESTIK NCA 2380 is a dual-cure acrylated epoxy adhesive designed for active alignment camera module assembly. It offers UV light activation for temporary cure, followed by a low-temperature thermal cure for final bonding. Key benefits include:

  • UV curable for fast processing
  • Excellent adhesion to multiple substrates
  • Good flow performance for precision applications
  • High glass transition temperature (Tg) of 95°C
  • Low Coefficient of Thermal Expansion (CTE)

2. Applications

  • Active alignment of camera modules
  • Bonding temperature-sensitive electronic components
  • Compatible substrates: Aluminum (Al), Polybutylene Terephthalate (PBT), Liquid Crystal Polymer (LCP), and Printed Circuit Boards (PCB)
