LOCTITE® HY 4090 Universal Structural Bonder
Features and Benefits
Available sizes:
LOCTITE HY 4090 is an off-white to light yellow, high viscosity, 2-part hybrid, universal structural bonder with high humidity and vibration resistance.
LOCTITE® HY 4090 is a high viscosity, off-white to light yellow gel. It opens completely new application areas in structural bonding – for the very first time combining instant adhesive properties with those for epoxies to give more striking benefits. Fixture time of 90 - 180 seconds and suitable for gaps up to 5 mm. Resistant to vibration, shock loads and impacts with the ability to bond dissimilar substrates. Best application results are achieved with LOCTITE® 50 ml Adhesive Mixing Nozzle (item 1826921), LOCTITE® 400 ml Adhesive Mixing Nozzle (item 1573135), LOCTITE® 96001 (item 267452) or LOCTITE® 983439 (item 218311).
- Vibration, shock loads and impact resistance
- Temperature resistance up to 150 °C
- Gap filling up to 5mm
- High moisture resistance
- UV resistant allowing outdoor applications
- Viscoelastic & Finite Strain FEA data cards available

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 7070™) to degrease and clean surfaces prior to applying the adhesive.
2. Preparation of Cartridge
Place cartridge in dispense gun. Remove cap from cartridge. Dispense a small amount so that material is coming out of both sides of cartridge. 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.
