LOCTITE® 402 Instant Adhesive
Features and Benefits
Available sizes:
LOCTITE 402 is a medium viscosity, high temperature, durable, and fast-setting instant adhesive ideal for a wide range of substrates.
LOCTITE® 402 is an ultra-performing, fast-setting instant adhesive that provides reliable performance under extreme operating temperatures up to 135°C. LOCTITE 402 bonds quickly and strongly to a wide range of plastic, rubber, and metal substrates – including difficult-to-bond materials. LOCTITE 402 is ideally suited for the joining of small parts in high-speed production applications as well as quick, on-the-go repairs.
- Ultra-performance adhesive
- Temperature resistance up to 135°C/275°F
- Unique, patented formula with reduced hazardous ingredients
- Perfect for quick repairs as well as high performance production applications

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 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.
