Gel instant adhesive designed for assembling parts with varying or undefined bond gaps up to 5mm (0.2"), and/or for applications where the complete cure of excess adhesive is a must. Works even on porous materials.
When you need an instant adhesive with excellent gap-filling capabilities on a variety of substrates, LOCTITE® 3090 is a great choice. This 2-part product is designed for assembling parts with varying or undefined bond gaps up to 5mm (0.2"), or for applications where complete cure of excess adhesive is a must. It has excellent bonding characteristics to a variety of substrates, including plastics, rubbers, metals, and even porous materials like wood, paper, leather and fabric. The gel consistency prevents adhesive flow even on vertical surfaces, and temperature resistance is from -40°C to 80°C (-40°F to 176°F). For best application results, use the LOCTITE cyanoacrylate mixing nozzle contained in the kit.
  • Gap filling up to 5mm (0.02")
  • Gel consistency prevents adhesive flow, even on vertical surfaces
  • Excellent bonding of all common substrates
  • Precise and clean application with provided syringe

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 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.

4. Assembly

Assemble parts immediately. The parts should be accurately located as the short fixture time leaves little opportunity for adjustment. Bond should be held or clamped until the adhesive has fixtured. Hint: if necessary, excess product can be cured by activator LOCTITE® SF 7452. Spray or drop activator onto excess product.
