A toughened and thermally resistant, high viscosity instant adhesive for high temperature applications or where impact resistance is needed.
LOCTITE® 4204 is a clear, toughened and thermally resistant, high viscosity instant adhesive. It has good impact, peel and temperature performance up to 250°F (121°C). It has a fixture time of 75 seconds and it is suited for the assembly of metals, rubbers, and plastics, including difficult-to-bond plastics (PP, PE, PTFE) when used with a primer such as LOCTITE® SF 770.
  • Operating temperatures from -65°F to 250°F
  • Toughened for impact resistance
  • Excellent peel, impact and sheer strength
  • High viscosity for gaps up to 0.008 in

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. Spray or drop activator onto excess product.

Equipment

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