Volkswagen Golf Service & Repair Manual: Permanent underbody protection -D 314 D38 M2-, light
| Permanent underbody protection -D 314 D38 M2-, light |
| Permanent underbody protection -D 314 D38 M2- is a light,
transparent, non-hiding compound based on an aqueous synthetic
resin dispersion which can be sprayed on using a UBS, paint or
filler gun. |
| Drying time depends on the coat thickness as well as the
ambient temperature and humidity. Good ventilation and higher
temperatures accelerate drying. |
| The dried film adheres well to sheet metal, which is
galvanised or coated with electrophoretic primer, as well as to
painted substrates. Due to the great resistance to abrasion and
flexibility under cold conditions, permanent underbody
protection exhibits excellent stone-chipping protection. |
| The permanent underbody protection can be quickly worked on
or overpainted with water-based paints. |
| After air drying about 2 to 3 hours, the material can be
overpainted with conventional solvent-based paint systems as
well. |
| The permanent underbody protection may be pigmented and
mixed with water-based paints and may be thinned with
demineralised water. When adding pigment, up to 30% by volume
ready-to-spray water-based paint may be added. |
| The mixing ratio, spray pressure and spray distance may be
varied to achieve smooth surfaces or fine or coarse structures. |
| The material is only temporarily resistant to naphtha and
cold cleaners. |
| Permanent underbody protection -D 314 D38 M2- is suitable
for repairing underbodies, wheel housings, and front end and
rear ends and can be applied to visible parts such as door sills
as paintable protection against stone chipping, road salt and
corrosion due to moisture. |
| The material is suitable for repairing various surface
structures following repairs to all sorts of vehicles. |
| The variable options for pigmentation offer a special
advantage. Any scratches and stone chipping are thus rendered as
inconspicuous as possible. |
 Note
| Before using, read the safety measures and recommendations
in the safety data sheet. |
| Even for products which are not required by law to be
labelled, the usual safety measures for chemical products must
be observed. |
| The surfaces to be treated must be cleaned thoroughly
beforehand, and any rust must be removed. |
| The surfaces must be dry and free of dirt, dust and grease. |
| Surfaces which are not to be coated should be covered with
paper. |
| Bare steel surfaces are to be primed before application of
permanent underbody protection. |
| Permanent underbody protection may be applied to all common
sealing materials except silicone and exhibits good adhesion. |
| Sealants containing softeners may cause the surface of
permanent underbody protection to soften or exhibit slight
stickiness. However, the material will not lose its adhesive
property as a result. |
| Shake the can thoroughly before use. |
| Permanent underbody protection must not be applied with
rusty filler guns or paint guns. The material may be thinned
with up to 10% by volume distilled or demineralised water to
achieve the required viscosity. |
| The first coat should not be applied too heavily (
spray pass). |
| The Permanent underbody protection can be mixed with up to
30% by volume ready-to-spray water-based paints. |
| To recreate common structures, best results will be achieved
with 10-15% ready-to-spray paint mixture. |
| The material should be filtered through a paint sieve before
application. |
Caution
| Do not spray onto joints, engine, propshaft,
exhaust, catalytic converter or brake system. |
| Blow out the UBS gun immediately after use and then
clean it with plastic cleaner -D 195 850 A1-D 195 850
A1. |
| If the UBS gun becomes blocked, the can may burst. |
| Observe the operating instructions of the UBS gun. |
|
Note
| Permanent underbody protection can be overpainted with both
water-based and solvent-based paints. Due to the large number of
systems available in the market, test spraying is necessary. |
| 1 - |
Overpainting with water-based paints: |
| – |
After drying to a matt surface and up to 72 hours following
application, permanent underbody protection can be overpainted
using water-based paints. |
| 2 - |
Overpainting with conventional solvent-based paints: |
| – |
After drying thoroughly and up to 72 hours following
application, permanent underbody protection can be overpainted
using solvent-based paints. The material is a fast-drying
thick-coat system. When accelerating drying with forced air,
ensure that the fast-developed skin is not blown away over the
still-wet material on which it is floating. This can cause
cracking in the finish. |
| Splashes on painted surfaces should be removed immediately
using plastic cleaner -D 195 850 A1-. |
| Equipment and soiled parts must be cleaned with water
immediately after application, if necessary using a water-based
cleaning agent. Do not use any solvent-based cleaning agents,
for these cause coagulation. After drying, permanent underbody
protection can only be removed mechanically. |
