1. Product Overview

LOCTITE® HY 4070™ is a two-component hybrid adhesive combining cyanoacrylate and acrylic technologies. It offers fast fixture times at room temperature in bond gaps up to 5 mm, with excellent adhesion to various substrates such as plastics, rubbers, and metals. It is designed for applications requiring complete cure of excess adhesive, as well as resistance to temperature and moisture. Its gel consistency prevents flow, making it suitable for vertical applications.

2. Applications

  • Bonding plastics, rubbers, and metals
  • Applications requiring gap filling up to 5 mm
  • Situations where temperature and moisture resistance are necessary
  • Vertical surface bonding due to its non-sag gel consistency
