1. Introduction

1.1. This COP describes the procedure that should be used when preparing and applying

V9500 adhesive.

2. Requirements

2.1. To achieve a good flexible adhesive joint and a high performance environmental seal.

Materials

3.1. V9500 duo-pack adhesive

3.2. Solvent based degreasing agent of Isopropyl Alcohol (IPA)

3.3. Small crucible (container)

3.4. Emery Paper

3.5. Tissue wipes

3.6. Wooden spatula

4. Equipment

4.1. N/A

5. Precautions

5.1. The use of rubber gloves or a suitable barrier cream is recommended when applying the

adhesive and when using solvents.

5.2. Use solvents in a well-ventilated area.

5.3. Wear safety glasses when using solvents.

5.4. Avoid repeated or prolonged skin contact. Wash hands before eating or smoking. Avoid

contact with eyes. If the eyes do become contaminated, flush with water and obtain

medical assistance.

5.5. Adhere to local codes and regulations relating to safe working practices.

6. Procedure

6.1. Thoroughly degrease all bonding areas using Isopropyl Alcohol.

6.2. Abrade the bonding areas on the moulded part and cable jacket.

6.3. Duo-Pack

6.3.1. Fix the duo-pack into the dispensing gun and attach a nozzle. Purge a small

amount of adhesive through the nozzle to ensure correct mixing.

6.4. The adhesive should be applied to both surfaces that are to be bonded together.

Immediately after the recovery of the moulded part/tubing, remove any excess adhesive

using a clean dry tissue wipe. Re-heat joint to allow it to completely re-seal.

6.5. Ensure a small fillet of adhesive is visible at the outlets of the moulded part as indicated

in the inspection stage of the COP.

Note: When bonding to PTFE, chemically etch the tubing using Tetra etch (supplied by

W.L. Gore).

6.6. 24 hours at room temperature is sufficient to allow handling of the components.

Maximum strength is not typically reached until after 7 days. The adhesive joint should

not be flexed for inspection purposes until one of the following curing cycles has been

completed:-

Either 24 hours at 25°C

or 1 hour at 85°C

6.7. It is advantageous to oven cure wherever possible but the joint should be left to cool

before inspection.
