Volkswagen Touran Service Manual / General Paint Information / Original Products / General Application Instructions for Repair and Painting Systems / Paint System for Plastic Parts

This universal painting system enables you to safely and simply paint all plastic parts which can be usually found on the exterior. (Plastic types: PP, EPDM, ABS, PC, PPO, PBTP, UP-GF, PA, PVC, R-TPU, PUR) This technical reference material does not apply to factory primed plastic parts.

Base Surface

Pretreatment of base surfaces:

The base surface must be free of separating agents. Before cleaning the plastic parts, temper them for 60 minutes at +60 ℃ to sweat out the separating agents.

Clean with the Antistatic Plastic Cleaner -LKR 001 001 A3- or a milder Silicone Remover, Long -LSE 20 100 A3-.

The effort needed for cleaning depends on the type and quantity of the separating agent used. It is recommend to use a sanding pad to support the cleaning process. Let the thinner evaporate (for example, air-drying overnight at room temperature or 30-40 minutes at +60 C).

Before priming, lightly clean again using Antistatic Plastic Cleaner -LKR 001 001 A3- or Silicone Remover, Long -LSE 20 100 A3-.

The Paint Structure is not for Primed Plastic Parts.

Primer:

To attain secure adhesion, plastics must be primed after they have been thoroughly cleaned. Here the user has two choices:

1. -

Prime with Two-Part Synthetic Adhesion Filler, White - LKF 696 009- or Two-Part Synthetic Adhesion Filler, Black - LKF 696 040-. The Two-Part Synthetic Adhesion Filler, White -LKF 696 009- and the Two-Part Synthetic Adhesion Filler, Black -LKF 696 040- are primer/fillers which can be directly painted over with top coat.

2. -	Prime with Glazing Adhesion Promoter - ALO 822 000 10- and rework with elastified Two-part HS filler. Further processing with top coat and clear coat.

Notes for Damages:

Small scratches can be filled after priming with Two-Part Fine Filling Paste -LSP 784 002 A2-.

After sanding the filled patches insulate them:

1. -	With Two-Part Synthetic Adhesion Filler, White - LKF 696 009- or Two-Part Synthetic Adhesion Filler, Black - LKF 696 040-.

2. -	Prime with Glazing Adhesion Promoter - ALO 822 000 10- and rework with elastified Two-part HS. Further processing with top coat and clear coat.
