Product information

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).
