Volkswagen Tiguan Service and Repair Manual: Stone Chip Protection

Stone Chip Protection -AKR 311 KD1 05-

Definition:

• Stone Chip Protection -AKR 311 KD1 05-, black

Product Description

Stone Chip Protection -AKR 311 KD1 05- is a finely atomizing coating material with a synthetic resin basis.

The dried film adheres very well to cleaned base surfaces as well as to an bare and painted panel.

It is characterized by a high covering capacity, good protection against corrosion, high resistance to abrasion and therefore good protection against stone impacts.

After approximately seven minutes the quick-drying stone chip protection spray can be painted over using commercially available vehicle paint systems.

Oven drying at approximately 60 ºC (140 ºF) is possible without any problems.

Extraordinary mechanical stress (for example, automatic car washes) should be avoided in the first few weeks.

The mechanical load-bearing capacity of the painted surfaces can be found in the manufacturer's product specifications.

Application Instructions

Application

• Stone Chip Protection -AKR 311 KD1 05- is used on visible components, such as front and rear aprons and door sills to protect against stone impact, grit, and moisture corrosion. It can be quickly painted over.
• The material is also used to supplement stone chip protection linings, for work on particular points of a vehicle and during accident repair work.

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.

Processing

• Clean the surfaces to be treated with Stone Chip Protection well beforehand and remove any rust.
• The surfaces must be dry, free of grease, dirt and as much dust as possible.
• The material should be at room temperature during application.
• Shake the can thoroughly; when the ball bearings start to rattle, continue shaking for approximately one minute.
• Hold the can vertically when spraying and spray from a distance of 20 to 30 cm.
• If parts of the vehicle were covered before spraying, the covers should be removed before drying.
• Abrasion and corrosion protection increases with the layer thickness. For this reason one or two additional coats should be applied after a short ventilation time.
• To prevent spraying shadows the material is sprayed on in cross patterns.
• After use, the can and the valve should be held down and the valve sprayed until only propellant gas emerges.

Caution

Do not spray onto moving or high-temperature components such as the steering, engine, transmission, driveshaft, exhaust, catalytic converter and brake system.

Cleaning

• Splashes and paint mist can be removed immediately with gasoline.
• Dried material can only be removed with D or R thinner. Be careful with fresh paint!

Stone Chip Protection -AKR 311 KD1 10-

Definition:

• Stone Chip Protection -AKR 311 KD1 10-, black

Product Description

Stone Chip Protection -AKR 311 KD1 10- (black) is a water-soluble stone chip protection.

Properties:

• High elasticity
• Can be painted over with all top coats
• Particularly suitable for parts of passenger and work vehicles which are subject to gravel impact, such as front sections and door sill panels.

Application Instructions

Base Surface

Suitable base surfaces:

• Well sanded factory paint or old paint (including thermoplastic coatings)
• Surfaces treated with primer or filler

Caution

The Stone Chip Protection -AKR 311 KD1 10- may not be applied to PVB (acid-hardening) adhesive primers.

Pre-treatment of base surfaces:

• Carefully clean using Silicone Remover -LVM 020 000 A5- or Silicone Remover, Long -LVM 020 100 A5-.

• Then, sand.

• Use a suitable cleaning agent before reworking to ensure a clean and residue-free surface.

Processing

Spray device:

• Underbody spray gun with thread for disposable cans.

• If a finer surface is desired, the Stone Chip Protection -AKR 311 KD1 10- can be applied with a pressure feed spray gun according to the appropriate thinning.

Thinner:

• Thinnable with Purified Water -LVW 010 000 A5-

"High-Pressure Spraying" application type

• Processing viscosity 4 mm for +20 ºC (68 ºF), German Industry Standardization 53211
• Set spray nozzle (see manufacturer's information) to 3 to 4 bar.

Note

Do not dilute during the high-pressure spraying procedure. The delivery viscosity is the same as the application viscosity.

Application type "coat"

Application viscosity 4 mm gravity feed spray gun "Compliant":

• Depending on the addition of Purified Water -LVW 010 000 A5-

Adding 10 % thinner at +20 ºC (68 ºF) material temperature.

• Use a measuring stick to mix when pouring in the thinner.

• Set spray nozzle (see manufacturer's information): "Compliant" 1.5 to 2.0 mm.
• Set spray pressure (see manufacturer's information): "Compliant" to 2.0 to 2.5 bar.

• Apply two to three spray applications.
• The recommended dry layer thickness is between 150 and 300 um.

Drying

Air dry at +20 ºC (68 ºF) room temperature for 2 to 2.5 hours to 150 um and overnight to 300 um

Final drying time with forced drying is a minimum of 35 to 40 minutes.

Forced drying at +60 ºC (140 ºF) object temperature for 30 minutes to 150 and 300 um

Reworking

Can be painted over with:

• Water-based base paint and two-part HS clear coat
• Two-Part HS Top Coat

Personal Protective Equipment:

• Note the safety data sheets
• Wear the personal protective equipment during application
