NOTE:

•

A slash (/) in the abbreviation indicates that two
different materials make two-layer construction.
A plus sign (+) indicates that the two different
materials mix each other.

•

If the new material symbols designated by the
ISO differ form the old symbols, both are given,
with the old symbol being enclosed in brackets.

tion

•

*1: Temperature differs depending on the ratio of
the materials included.

•

*2: Impossible to fix the temperature due to the
multi-layer and foam material structure.

•

If an infra-red lamp is used for drying, use a
heat-resistant cover, etc., to protect parts.

HOW TO DISTINGUISH TYPES OF PLASTICS

M4090017000024

There are various methods that can be employed to
determine types of plastics, among them (1) using a
chemical solvent, etc., to check it chemically, (2)
scratching the material to determine its make-up, (3)
cutting of a small piece (where the scar can't be
seen) and burning it to judge by the way it burns, etc.
The following is an outline of the burning method,
which is a relatively simple method.

CORROSION PROTECTION

ANTICORROSION TREATMENT AT THE FACTORY

M4090019000031

Anticorrosion treatment at the time of production
includes the following measures.

THE USE OF GALVANIZED STEEL PLATE

Because galvanized steel plate has excellent corro-
sion resistance, it is used in areas which have a high
possibility of painting deficiency.

ZINC PHOSPHATE COATING

In order to improve the adhesive properties of the paint coat on
the steel plate, and also to improve the finish of the paint coat,
the entire body is coated with a film of zinc phosphate prior to
undergoing the electrodeposition undercoating process.

1. Final coat
2. Intermediate coat
3. Anticorrosion primer
4. Undercoat
5. Zinc phosphate film
6. Steel plate

CATIONIC ELECTRODEPOSITION UNDERCOATING

In the cationic electrodeposition method, the car
body is the negative pole, thus preventing damage to
the zinc plating of the galvanized body panels or to
the chemically formed phosphate crystals. This
method, therefore, maximizes the corrosion resis-
tance and the results obtained are much better than
those from conventional anionic electrodeposition.

BODY SEALING

Sealant has been applied to all body panel joints and seams in
order to provide resistance to water, dust, and corrosion.

UNDERBODY COATING

An underbody coating has been applied to the underside of the
floor pans, the inside of the doors, etc., in order to provide
resistance to vibration, corrosion, and wear.
