LOCTITE® 406 Instant Adhesive
Features and Benefits
Exceptionally low-viscosity instant adhesive forming an ultra thin adhesive film for smallest adhesive gaps in seconds (fast-fixturing). Suitable for plastics and elastomeric materials.
LOCTITE® 406 is a low viscosity instant adhesive designed especially for the fast bonding of plastics and rubbers. It fixes the adhering components in seconds and hardens very quickly, forming an ultra thin bond. Using the primer LOCTITE SF 770, the assembly of difficult-to-bond (PP, PE, PTFE) materials is possible.
- Rapid fixture time on plastic and rubber, including EPDM
- Assembles difficult-to-bond materials using LOCTITE SF 770 primer
- Very low viscosity product for small gaps
- Reduced hazardous ingredients for improved occupational safety

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 7063/7064/7070) 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 or LOCTITE® SF 7455 (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 or LOCTITE® SF 7455. Spray or drop activator onto excess product.
Equipment
For precise dispensing of small amounts of adhesive, the use of dispensing needles is recommended.
