Welding
Using a heater gun and PP welding rod, weld the beveled spot while melting both the rod and
damaged area.
(1) Welding rod
(2) Melt hatched area
(3) Section
NOTE:
• Melt the sections indicated by hatched area.
• Do not melt the welding rod until it flows out, in order to provide strength.
• Always keep the heater gun 1 to 2 cm (0.4 to 0.8 in) away from the welding spot.
• Leave the welded spot unattended until it cools completely.
10
Sanding (II)
Remove excess part of weld with a putty knife. If a drill or disc wheel is used instead of the knife,
operate it at a rate lower than 1,500 rpm and grind the excess part little by little. A higher rpm will
cause the PP substrate to melt from the heat.
Sand the welded spot smooth with #240 sand paper.
11
Masking
Mask the black substrate section using masking tape.
Recommended masking tape: Nichiban No. 533 or equivalent
12
Cleaning/degreas-
ing
Completely clean the entire coated area, using solvent similar to that used in procedure No. 4.
13
Primer coating
Apply a coat of primer to the repaired surface and its surrounding areas. Mask these areas, if
necessary.
Recommended primer: Mp/ 364 PP Primer
NOTE:
Be sure to apply a coat of primer using a spray gun at a pressure of 245 — 343 kPa (2.5 — 3.5 kg/cm
2
,
36 — 50 psi).
14
Leave unattended
Leave the repaired area unattended at 20°C (68°F) for 10 to 15 minutes until primer is half-dry.
NOTE:
If dirt or dust comes in contact with the coated area, wipe it off with a cloth dampened with alcohol.
(Do not use thinner since the coated area tends to melt.)
15
