Process
No.
Process name Job contents
1 Bumper mounting
Set bumper on paint worktable if required. Use
paint worktable conforming to inner shape of
bumper when possible.
G5M0164
2 Masking
Mask specified part (black base) with masking tape. Use masking tape for PP (example,
Nichiban No. 533, etc.).
3
Degreasing,
cleaning
Clean all parts to be painted with white gasoline, normal alcohol, etc. to remove dirt, oil, fat,
etc.
4 Primer paint Apply primer one to all parts to be painted, using air gun. Use primer (clear).
5 Drying
Dry at normal temperature [10 to 15 min. at 20C (68F)].
In half-dried condition, PP primer paint is dissolved by solvent, e.g. thinner, etc.
Therefore, if dust or dirt must be removed, use ordinary alcohol, etc.
6 Top coat paint (I)
Solid color Metallic color
Use section (block) paint for top coat.
Paint in use (for each color):
Solid paint
Hardener PB
Thinner T-301
Mixing ratio:
Main agent vs. hardener = 4:1
Viscosity: 10 ? 13 sec/20C (68F)
Film thickness: 35 ? 45
Spraying pressure: 245 ? 343 kPa
(2.5 ? 3.5 kg/cm
2
, 36 ? 50 psi)
Use section (block) paint for top coat.
Paint in use (for each color):
Metallic paint
Hardener PB
Thinner T-306
Mixing ratio:
Main agent vs. hardener = 10:1
Viscosity: 10 ? 13 sec/20C (68F)
Film thickness: 15 ? 20
Spraying pressure: 245 ? 343 kPa
(2.5 ? 3.5 kg/cm
2
, 36 ? 50 psi)
7 Drying Not required.
Dry at normal temperature [10 min. or more at
20C (68F)].
In half-dried condition, avoid dust, dirt.
8 Top coat paint (II) Not required.
Apply a clear coat to parts with top coat paint
(I), three times, at5?7minutes intervals.
Paint in use:
Metallic paint
Hardener PB
Thinner T-301
Mixing ratio: Clear vs. hardener = 6:1
Viscosity: 14 ? 16 sec/20C (68F)
Film thickness: 25 ? 30
Spraying pressure: 245 ? 343 kPa
(2.5 ? 3.5 kg/cm
2
, 36 ? 50 psi)
9 Drying
60C (140F), 60 min. or 80C (176F), 30 min.
If higher than 80C (176F), PP may be deformed. Keep maximum temperature of 80C
(176F).
10 Inspection Paint check.
11 Masking removal Remove masking in process No. 2.
