Volkswagen Touran Service Manual: Sprayable Sealant
| Sprayable Sealant -D 476 KD1 M2-, gray |
| Sprayable Sealant -D 476 KD2 M2-, black |
| Sprayable Sealant -D 476 KD1 M2-/- D 476 KD2 M2- is a
spray-on sealant with a MS polymer base. It hardens into a
rubber-elastic material with good abrasion resistance by
absorbing atmospheric moisture. |
| The film formation and hardening time depends on the
humidity and temperature. The hardening time is also affected by
the layer thickness. |
| These times can be shortened by raising the temperature and
humidity. Lower temperature and humidity levels delay the
hardening. |
| Sealant and weld sealant in one product |
| Can be sprayed and brushed |
| Can be painted over with conventional or water-based paints
up to three days after applying |
| Adheres to many materials without glass-/paint primer |
| Sound-dampening properties |
| Sprayable Sealant -D 476 KD1 M2-/-D 476 KD2 M2- is used to
seal welds in vehicle repair which have been sprayed at the
factory, for example in the engine, luggage, and passenger
compartment areas. Application tools (telescope spray gun or
Pneumatic Cartridge Gun -VAG1761/1-) can be used to reach every
desired weld. |
| The material is used as a surface coating to repair or
supplement PVC underbody coating or stone chip protection. |
| The adhesion surfaces must be dry, free of oil, dust, grease
and any other impurities. Cleaner FL is suitable to clean with. |
| Adhesion is improved if the contact surfaces are roughened
with a sanding pad. |
| If the material is painted over after completely drying,
then the painting preparatory work similar to the plastic
preparatory work is to be followed. |
 Note
| Before starting to apply, it is necessary to read the safety
measures and advice in the safety data sheet. |
| Even for products which are not required to be labeled by
law, the usual safety measures must be observed for chemical
emissions. |
Note
| Body areas and adhesion surfaces that are to be sealed must
be insulated with a Two-Part Filler before applying the
material. |
| Applying Sprayable Sealant -D 476 KD1 M2-/-D 476 KD2 M2-
from 310 mL aluminum cartridges can only be performed with the
telescope spray gun or Pneumatic Cartridge Gun -VAG1761/1-.
These application devices make is possible to apply the material
as a strip of material (sealant bead) or to spray it on by using
the dual-circuit air system. |
| The material can be both sprayed and brushed on. This means
that it is possible to imitate textured bonds and brushed
structures. |
| The sealed seams can be painted over as early as 15 to 30
minutes. |
| The corresponding settings on the application devices enable
the operator to imitate all textures specified by the
manufacturer quickly and conveniently. The spraying distance can
be used to vary the width and limit of the bond. Refer to the
operating instructions for details on handling and setting the
spray gun. |
| It is recommended to remove any unhardened sealant from the
tools using cleaner FL. Hardened material can only be removed
mechanically. |
| The Sprayable Sealant -D 476 KD1 M2-/-D 476 KD2 M2- can be
painted over with one-part and two-part repair paint and even
those containing alcohol as a solvent. |
| Painting over quickly does not prevent complete hardening,
it is, however, delayed. Do not wait longer than three days
before painting. |
| Before sealing or coating, phosphate and epoxy resin primers
are particularly suitable for corrosion protection. It is
imperative that the primers are dry before it is applied. |
| If the body area to be painted after an accident repair is
still to be coated with filler, filler primer or spray-on
filler, these materials must be applied before sealing or
coating with Sprayable Sealant -D 476 KD1 M2-/-D 476 KD2 M2-. |
| If a filler still needs to be applied after sealing or
coating with Sprayable Sealant -D 476 KD1 M2-/-D 476 KD2 M2-,
then the sealant should be at least six hours old and a filler
suitable for coating plastic is used. |
| The Sprayable Sealant -D 476 KD1 M2-/-D 476 KD2 M2- is not
compatible with fresh one-part polyurethane material.
Polyurethane products must be solidified before they are sprayed
with the sealant. |
| The material should not be treated with aromatic solvent
systems. As a result, it can partially dissolve or swell the
sealant. |
