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.

 

Type	Description
Type 1	Bead application (1) (round, flat, spread seam)
Type 2	Surface coating (2) (rough structure)
Type 3	Surface coating (2) (fine structure)
Type 4	Surface coating (2) (very fine structure)
Type 5	Surface coating (2) (variable structure)

 

 

The following illustrates the individual applications using the Vectra - as an example.

Applications   Sealing of Body Front Section   ·     Wheel well   ·     Front frame side member   ·     Bulkhead connection   ·     Front crossmember   Sealing of Body Rear Section   ·     Lower rear end panel   ·     Floor   ·     Inner wheel well   ·     Spare wheel well
Sealing of Rear Quarter Panel   ·     Side roof, rear   ·     Rear lamp mount   Sealing of Wheel Well   ·     Inner wheel well   ·     Sill panelling connection
Sealing of Body Underside   ·     Front frame side member ·     Wheel well ·     Floor, side ·     Transmission tunnel   Note: Remove wing protective panelling; spray area behind (A pillar).   Sealing of Body Tail   ·     Rear frame side member ·     Rear frame crossmember ·     Spare wheel well ·     Rear wheel well ·     Body tail end   Note: Remove protective panelling partially; spray area behind.

 

 

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).

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. ·     Wear a head covering.

 

 

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 4     Black union nut for clamping nozzle cartridges with multifunction use
