LOCTITE® 402 - 20 g Bottle Instant Adhesive
Features and Benefits
Available sizes:
A fast-fixturing, ultra-performance instant adhesive that provides reliable performance under extreme operating temperatures up to 135°C (275°F). It is suitable for use in medical device assembly.
LOCTITE® 402 is a high temperature and fast-fixturing instant adhesive that reliably and strongly bonds to a wide range of plastic, rubber, and metal substrates. It is ideally suited for the joining of small parts in high-speed production applications as well as quick, on-the-go repairs. Using the primer LOCTITE® SF 770 (or LOCTITE® SF 7701 for medical device assembly), the assembly of difficult-to-bond (PP, PE, PTFE) materials is possible.
- Ultra-performance adhesive providing resistance up to 135°C (275°F) and fast fixture
- ISO-10993 biocompatible
- Ideal for quick repairs and high speed production applications
- Unique, patented formula with reduced hazardous ingredients
- Assembles difficult-to-bond materials using LOCTITE SF 770 or SF 7701 primer

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) 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 7239 or 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 7458 or LOCTITE® SF 7455. 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
Apply adhesive onto one side and 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 7458 or LOCTITE® SF 7455/7452. Spray or drop activator onto excess product.
Equipment
For precise dispensing of small amounts of adhesive, the use of dispensing needles is recommended.
