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 7701™ 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 713™ (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 713™. Spray or drop activator onto excess product.
