LOCTITE® HY 4090 is a high-viscosity, off-white to pale yellow gel product. It opens up entirely new application areas for structural bonding — for the first time combining the bonding properties of instant adhesives and epoxies to deliver outstanding performance. This product fixtures within 90 to 180 seconds and can fill gaps up to 5 millimetres. It offers vibration and impact resistance. Optimal application results are achieved when used with LOCTITE® 50 ml adhesive mixing nozzle (IDH 1826921), LOCTITE® 400 ml adhesive mixing nozzle (IDH 1573135), LOCTITE® 96001 (IDH 267452) or LOCTITE® 983439 (IDH 218311).
Resistant to vibration, impact loads and shocks Withstands high temperatures up to 150°C Fills gaps up to 5 mm High moisture resistance UV resistant, suitable for outdoor applications
