LOCTITE® HY 4070 Universal Bonder
Features and Benefits
A 2-part, fast-fixturing adhesive with excellent moisture and temperature resistance.
LOCTITE® HY 4070 Universal Bonder is a 2-part, fast fixturing, cyanoacrylate/acrylic-hybrid adhesive that performs brilliantly on various substrates, including most plastics, rubbers and metals. It’s designed for the assembly of parts with bond gaps of up to 5 mm (0.2") and for applications where the complete cure of excess adhesive is a must. It has a gel consistency, which prevents adhesive flow even on vertical surfaces. Ideal for applications where temperature and moisture resistance are required. Best application results are achieved with use of the LOCTITE cyanoacrylate mixing nozzle.

How to
Step by Step Guide
1. Preparation - Cleaning
It is recommended to use the correct LOCTITE® cleaner for the surface to be bonded (such as LOCTITE® SF 7063 or SF 7070) to degrease and clean surfaces prior to applying the adhesive.
2. Preparation of Cartridge
Place plunger in the back of the cartridge. Remove cap from cartridge. Dispense a small amount so that material is coming out of both sides. Attach mix nozzle and dispense a bead at least half of the length of the nozzle. The material is ready to use.
3. Application
Apply a bead of material to one of the surfaces to be bonded. Join the parts and fixture in a way to prevent movement of the part until handling strength is obtained.
