LOCTITE® 406 Instant Adhesive

Known as Loctite 406 Prism Instant Adhesive

Features and Benefits

LOCTITE 406 is a low viscosity, fast curing instant adhesive that is ideal for bonding plastics and elastomeric materials where very fast fixturing is required.
LOCTITE® 406 is an instant adhesive designed especially for the fast bonding of plastics and rubbers. This product offers exceptionally low viscosity. When combined with LOCTITE primers for cyanoacrylates, it can also be used on difficult-to-bond plastics.
  • Rapid bonding of plastic & rubber, including EPDM
  • LOCTITE 770 or LOCTITE 7239 primer improves adhesion of difficult-to-bond substrates
  • Low viscosity

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 - Priming

To improve adhesion on difficult to bond plastic surfaces, apply LOCTITE® SF 770 to the bond area by brushing or dipping. Avoid applying excess primer. Allow the primer to dry.

3. Preparation - Activation

If cure speed is too slow, use appropriate activator LOCTITE® SF 7452 (see cure speed vs activator graph in TDS). Apply activator to one bond surface by spray, brush or dipping (not primed surfaces). Allow the activator to dry.

4. Application

Apply adhesive onto one side/part.

5. 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.
