Subject:

Spray Seam Sealing for Body Repairs

Vehicles:

All

General:

This Technical Information Bulletin describes a new system for working with universally applicable Spray Seam Sealing (SSS) for body repairs. This system is a useful, economical addition to the existing sealing methods.

The SSS has the following performance characteristics:

· Appearance of repaired seams corresponds to production seals.

· Good adhesion on metal, primed surfaces and colour coats

· Does not contain isocyanate, silicon and polyvinyl chloride (PVC)

· Fast drying, age - resistant, noise - insulating, wear - resistant

· Increased corrosion protection

· Resistant to ultraviolet light

· Good for top - coating

General Description

The SSS is a sealing paste containing solvents based on polyether, with reacts with humidity to cross - link into a permanently elastic, wear - resistant product.

The curing times are dependent on the air humidity, temperature and thickness of layer.

The system consists of the Sealing Material 90 543 279 / 15 03 176, available in cartridges (310 mm) with the corresponding replacement nozzles. It is processed using the Telescopic Pistol MKM - 950.

It is also possible to use the Telescopic Pistol MKM - 950 to process conventional 310 ml cartridges. A special union nut is enclosed for this purpose (multi - functional use).

Applications

The SSS can be used in body repair for sealing welding seams, edges, folds and for surface application in the areas specified in sections 2. 1 to 2. 6.

The telescopic pistol can be used to produce various seam shapes, allowing the sealing seams used in production to be reproduced.

Note:

Limitations

A Always apply SSS to primed surfaces.

Important:

Loss of adhesion will result if SSS is applied to surfaces treated with spot weld paint, zinc dust paint and zinc spray.

B Only apply SSS to hardened materials (sealing materials, adhesive).

Operations - Details

Step A Service Literature

A1 Service Literature

The following Service literature is available:

· This Technical Information Bulletin about the Spray Seam Sealing System

· The new system will be included in revised editions of Service Instructions and Corrosion Protection brochures.

A2 Safety Measures

In general, the user must always be protected against hazards and stress. The onus of responsibility lies with the employer or superior to ensure that work can be performed without risk. National legislation, guidelines and regulations on labour safety must be observed, such as:

· Accident prevention regulations and guidelines from the authorities of legal work associations

· Ordinances about flammable fluids

· Workplace ordinances

· Workshop guidelines

· Materials ordinances

These regulations may vary from country to country.

Process SSS in closed, well - ventilated workrooms only.

Step A Service Literature

A2 Safety Measures

Chemicals can affect the human body via swallowing, skin contact or via the respiratory organs.

The following basic principles must always be observed:

To protect the eyes

· Wear protective goggles.

· If SSS gets into the eyes, rinse with plenty of water.

To protect the respiratory organs

· Use SSS in well ventilated rooms or use an air extract system..

· Use respiratory equipment.

To protect the skin

· Wear protective clothing and gloves.

· If SSS comes into contact with skin, wash with plenty of water and soap.

Step A Service Literature

A2 Safety Measures

· Check that the telescopic pistol union nut is firmly seated.

· Uncouple the air line before changing the cartridge.

· Use only undamaged cartridges.

· Do not point the telescopic pistol at people.

Step B Materials, Tools

B1 Preparation

The following materials and tools are required (see also section 7 "Parts"):

1 Telescopic Pistol MKM - 950

2 Plug connection

3 Blue union nut for processing with spray seam sealant

The following materials and tools are required (see also section 7 "Parts"):

5 Double nozzle

6 Cartridge too) for opening flanged cover and diaphragm

7 Silicon remover

Step C Preparation of Body Surface

C1 Sand surface

· Roughen surface with emery paper

C2 Clean seam area

· The seam area must be clean, dry and free from grease before application.

Use silicon remover to clean.

C3 Priming (filling)

Apply primer to bare areas only.

Step D Tool Preparation

D1 Prepare cartridge

· Open cartridge.

Press in flanged lid on top of cartridge using enclosed tool. (1)

Use drift to punch through recessed membrane on nozzle connection. (2)

· Screw material nozzle onto cartridge. (3)

D2 Screw on air nozzle

· Screw blue union nut onto thread. (1)

· Screw air nozzle on to stop in blue union nut. (2)

D3 Connect compressed air hose

· Use Æ 6 mm / 0. 24 in. compressed air hose, maximum operating pressure 10 bar.

The telescopic pistol has an integrated pressure limiter which prevents the pressure from exceeding 6 bar.

· Screw plug connection firmly into inner thread on pistol handle. (3)

D4 Only for multi - functional use

Step E Nozzle Adjustment

E1 Adjustment the setting screws

· The setting screws on the pistol are used to separately adjust the material flow and the spray air.

1 - Red setting screw:

Adjustment of material flow

2 - Blue setting screw:

Step F Application

F1 Nozzle adjustments and spray patterns

Check nozzle adjustment before application. Hold pistol as perpendicularly and at right angles to the surface.

· Adjustment material flow (red setting screw) accordingly.

· Material flow high

· Material flow low

· Material flow very low (if necessary)

Step G Cleaning

G1 Nozzle change

· As the nozzles are exchanged along with the SSS cartridge, cleaning is not necessary.

G2 Cleaning equipment

· Clean dirty equipment with silicon remover.

· Remove dried SSS mechanically from dirty equipment.

· Always keep thread on the pistol clean and treat occasionally with commercially available grease.

Step H Top - coating / Assembly Stability

Before painting or further processing on the SSS, note the following processing information:

Top°- coating

· 20 minutes to

72 hours

· After 20 minutes (skin starts to form), painting can be carried out as specified in the familiar OPEL paint repair systems.

Assembly stability

· No waiting period

· 60 minutes

· After oven drying

· Bead application (air drying)

Notes: External paint shops must be informed about this processing information. At present, there is no data on the use of water - based paint. The corresponding tests are still underway and will be published on completion.

Step I Environmental Protection, Disposal

I1 Dispose of materials as specified by national regulations.
