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 ºC 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 ºC).

• 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. 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. 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. 1
   With Two-Part Synthetic Adhesion Filler, White - LKF 696 009- or Two-Part Synthetic Adhesion Filler, Black - LKF 696 040-.
2. 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.

For the application instructions, evaporating and drying times refer to the respective technical application information.

The Addition of Two-Part Elastic Additive -ALZ 011 001- in Two-part HS Filler.

• 15 % for rigid and semi-rigid plastics
• 30 % for highly flexible plastics.

For the application refer to the technical application information of the respective filler.

Note

Painted plastic parts may not be cleaned with a high-pressure cleaner before 6 weeks have passed. The minimum distance between the nozzle and the object is 30 cm.

One-Coat Painting

Top Coat:

• Mix two-part HS top coat with 15 % Two-Part Elastic Additive -ALZ 011 001- then combine this mixture.

• Mixture ratio 3:1 with two-part VHS hardener and 15 % Two-Part Thinner, Special -LVM 009 200 A2-.

Processing:

• Apply 1.5 coats.

• Let air dry overnight at +20 ºC (68ºF)or after 5 to 10 minute final drying time, 30 to 40 minutes at +60 ºC (140ºF). When using Two-Part Elastic Additive -ALZ 011 001- use longer drying times.

Two-Coat Painting Solid, Metallic, Pearls

Base Paint:

• Water-based base paint with 10 % Purified Water -LVW 010 000 A5-.

Processing:

• Apply 1.5 coats.

Clear Coats:

• Mix the two-part HS clear coat with Two-Part Elastic Additive -ALZ 011 001-.

Processing:

• According to the respective technical application instructions of the clear coat. Refer to → Chapter "Clear Coats".

Drying:

Let air dry overnight at +20 ºC (68ºF) or after 10 minute final drying time, 40 to 45 minutes at +60 ºC (140 ºF). When using Two-Part Elastic Additive -ALZ 011 001- use longer drying times.

Painting with Satin Finish Paint Shades

One-Coat Painting, Top Coat:

• Mix two-part top coat in a 1:1 ratio with Two-Part Matting Component -ALN 775 106- then combine this mixture.

Mixture ratio 4:1 with two-part VHS hardener and 15 % Two-Part Thinner, Special -LVM 009 200 A2-.

Processing:

• Apply with two spray applications with 5 to 10 minutes' intermediate drying time for an even paint film surface.

Drying:

• Let air dry overnight at +20 ºC (68ºF) or after 5 to 10 minutes final drying time 30 to 40 minutes at +60 ºC (140 ºF).

Painting in Color Shades with Texture

One-Coat Painting, Top Coat:

• Mix two-part HS top coat in a 1:1 ration with Structuring Component, Rough/Fine -ALN 775 107/108- then combine this mixture.

• Mixture ratio 4:1 with two-part VHS hardener and 15 % Two-Part Thinner, Special -LVM 009 200 A2-.

Processing:

• Two spray applications:

1. Apply normal application, 5 to 10 minutes with intermediate ventilation.

2. Apply the spray coat according to the desired texture.

• Let air dry overnight at +20 ºC (68 ºF) or after 5 to 10 minutes final drying time 30 to 40 minutes at +60 ºC (140 ºF).

Personal Protective Equipment:

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