LOCTITE 401 Instant Adhesive

Known as Loctite 401 Prism Instant Adhesive

Features and Benefits

LOCTITE 401 is a general purpose, fast curing, instant adhesive that is ideal for use on porous substrates.
LOCTITE® 401 is a fast curing instant adhesive designed for the assembly of difficult-to-bond materials requiring uniform stress distribution and high tensile and/or shear strength. The product provides for the rapid bonding of a wide range of materials, including metals, plastics and elastomers. LOCTITE 401 is also suited to bonding porous materials such as wood, paper, leather and fabric. Perfect for all quick repairs and all types of small emergency repairs.
  • Universal instant adhesive
  • Very high strength on close-fitting parts
  • Perfect for all quick repairs and all types of small emergency repairs.
  • Bonds a wide range of similar or dissimilar substrates (metals, rubber, wood, cardboard, ceramics as well as most plastics)

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 7458™ or LOCTITE® SF 7452™. Spray or drop activator onto excess product.

Equipment

For precise dispensing of small amounts of adhesive, the use of dispensing needles is recommended.
