1. How to identify the model of the paint?
The paint model is divided into three parts.
The first part is the film-forming substance, which is the code in the paint classification table, expressed in Chinese pinyin letters;
The second part is the base name, represented by two digits. The third part is the serial number, expressed in Arabic numerals, in order to distinguish the composition of the same species.
There is a short dash between the second part and the third part. Its function is to separate the basic name from the serial number. The model formed in this way can only represent one type of French material.

2. There are several kinds of auxiliary materials for coatings, and how to express their models?
Auxiliary materials in coatings can be divided into five types according to their uses:
Thinner (code-named X);
Moisture-proof agent (code-named F),
Drier (code-named G);
Paint remover (code-named T);
Curing agent (code-named H).
The model number of auxiliary materials is divided into two parts:
The first part is the types of auxiliary materials, represented by the Chinese pinyin letters x, F, G, T, and H.
The second part is the serial number, expressed in Arabic numerals.
