12.11 Plastic Panel Information and
Repair

12.11.1 Description and Operation
12.11.1.1 Description and Operation

The current interior and exterior cover part materials are mainly
modified PP, ABS, PC + ABS, PVC (artificial leather material),
all of which are thermoplastic materials or modified
thermoplastic materials. Some interior and exterior non-cover
part materials are POM, PA type and HDPE type materials.
Thermosetting plastics are rarely used in interior and exterior
parts. Only the ashtray is made from thermosetting plastics.
Thermosetting plastics are mainly used in electrical and
electronic structural components. ideally the thermoplastic
components are repaired with a hot iron welding, but usually
the thermoplastic components are replaced. Thermosetting
plastics can be repaired with epoxy resin, or other more rigid
two-component repair materials. This chapter is only a brief
introduction to its repair practices and repair is not
recommended.

Plastic Types:
Thermosetting plastic is defined as a type of plastic that can be
cured or have insoluble (melt) properties when heated, such as
phenolic, epoxy plastics. Thermoplastic is defined as a type of
plastic that can be repeatedly hardened after heated and soften
after cooled within a specific temperature, such as
polyethylene,

PTFE

and

etc.

Thermoplastics

and

thermosetting plastics can be either hard plastics or soft
plastics.

12.11.2 Removal and Installation
12.11.2.1 Plastic Repair Notices

1. Apply protective cream to any exposed skin to avoid skin

irritation.

2. Wear rubber gloves.

3. When use compressed air or sanding, wear protective

goggles.

4. Remove any mixture that comes into contact with skin

immediately, as the mixture will become solid very quickly.

5. When grinding or sanding, wear a dust mask and protective

goggles.

6. Wash the skin with cold water to minimize irritation caused

by resin dust.

7. Avoid dropping repair materials onto clothes.

8. Use repair materials in a well ventilated environment, as the

dust produced during repairs is toxic.

9. After use, close all the repair material containers. Dust or

moisture will contaminate the repair materials and weaken
the repair quality.

12.11.2.2 Thermosetting Plastic Dent Repair

1. Clean the area to be repaired.

2. Heat the dent part with a blower until the appropriate tools

can be used to press flat the dent.

3. Grind the dent area with sandpaper/emery paper.

4. Clean the dent area with cleaning agent and leave it dry 5

min.

5. Apply a thin layer of adhesive and leave it dry 10 min.

6. Fill the uneven surface with adhesive and smooth out with

putty knife.

7. Use an infrared light to accelerate the curing process and

raise the temperature to 60-70°C (140-158 ºF), heat 15 min.

8. Polish the dent area with sanding paper.

9. Remove dust debris.

10. Apply a thin layer of adhesive and leave it dry 10 min.

11. Restore the plastic surface according to the plastic surface

repair process.

12.11.2.3 Thermosetting Plastic Scratch
Repair

1. Clean the area to be repaired.

2. Use sanding paper to remove protruding material.

3. Clean the area with cleaning agent and leave it dry 5 min.

4. Apply a thin layer of adhesive and leave it dry 10 min.

5. Fill the uneven surface with adhesive and smooth out with

putty knife.

6. Use an infrared light to accelerate the curing process and

raise the temperature to 60-70°C (140-158 ºF), heat 15 min.

7. Polish the dent area with sanding paper.

8. Remove dust debris.

9. Apply a thin layer of adhesive and leave it dry 10 min.

10. Restore the plastic surface according to the plastic surface

repair process.

12.11.2.4 Thermosetting Plastic Crack Repair
(length less than 100 mm)

1. Clean the area to be repaired.

2. Pry open the crack tip 5 mm (0.19 in) long, and polish it into

a V-shape crack to eliminate stress and protruding
materials.

3. Clean the area with cleaning agent and leave it dry 5 min.

4. Apply a thin layer of adhesive and leave it dry 10 min.

5. Apply the adhesive to the back of the repair

part,overlapping the damaged part at least 20 mm (0.79 in).

6. Use an infrared light to accelerate the curing process and

raise the temperature to 60-70°C (140-158 ºF), heat 15 min.

7. Fill the crack area with adhesive and smooth out with putty

knife.

8. Use an infrared light to accelerate the crack tip curing

process.

9. Polish the dent area with sanding paper.

10. Apply a thin layer of adhesive and leave it dry 10 min.

11. Remove dust debris.

12. Apply a thin layer of adhesive and leave it dry 10 min.

13. Restore the plastic surface according to the plastic surface

repair process.

12.12 Collision Repair

12.12.1 Specifications
12.12.1.1 Collision Repair Materials

Vehicle body collisions will lead to structural deformation, metal
penal cracking and solder joints seal off. Collisions will also
cause damage to the engine, chassis and other components.

To carry out body collision repair, materials such as adhesives,
sealants, anti-loose agent, surface protection materials, anti-
corrosion materials and other chemical materials may be used.
Please strictly follow the product instructions, scope of use and
the standard operation instructions. During the body repair
process, choose repair materials that suit the application. The
following table lists the repair materials that maybe used in the
body repairs for reference.
