LOCTITE® 401 Instant Adhesive
Features and Benefits
Available sizes:
A surface-insensitive, fast-fixturing instant adhesive that provides high shear strength on a wide range of materials, including difficult-to-bond substrates.
LOCTITE® 401 is a fast-fixturing instant adhesive (industrial grade) designed for the assembly of a wide range of materials where uniform stress distribution and high tensile and/or shear strength are required. Using primer LOCTITE® SF 770, the assembly of difficult-to-bond materials (PP, PE, PTFE) is possible. In addition, it is suited for bonding porous materials such as wood, paper, leather and fabric.
- Universal industrial instant adhesive
- Very high strength on close-fitting parts
- Reduced hazardous ingredients for improved occupational safety
- Bonds a wide range of similar or dissimilar substrates (metals, rubber, wood, cardboard, ceramics, and most plastics)
- Assembles difficult-to-bond materials using LOCTITE SF 770 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 7063/7064/7070) 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 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 (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 7458 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.
