Do you know about coating inspection and analysis?

Question: What are the types of coatings?

Answer: According to the form, it can be divided into solid paint and liquid paint; according to the purpose, it is divided into industrial coatings and civil coatings.
Industrial coatings are divided into color board coatings, automotive coatings, architectural coatings, wood coatings, aircraft skin paints, etc.

Question: What is the purpose of coating analysis and testing?

Answer: The performance of the coating determines the quality of the coating and the purpose of the coating, and the performance of the coating is multifaceted
.
For the evaluation of coating properties from different angles, we developed a number of test methods, including the detection of both the coating film properties and performance testing itself paint line coatingol.

1.
The test can provide data for the formula design and process conditions of the selected product;

2.
Through the analysis and testing of the coating, the quality of the coating product can be accurately reflected and the product quality controlled;

3.
Carry out basic theoretical research to find out the relationship between components and performance based on the data obtained from the detection test, so as to discover the existing problems of the original product and the direction of improvement, and provide a basis for the development of new products
.

Question: What are the common technical indicators for coating analysis and testing?

Answer: The indicators of the physical state of the coating include density, viscosity, etc.
The optical properties of the coating film include gloss, color, etc.
; the indicators of mechanical properties include hardness, flexibility, etc.

Common standards for hardness testing are: ASTM D3363, ISO 15184, GB/T 6739, JIS K5600-5-4;

Common standards for thickness testing are: ASTM D7091, ASTM D1186, ISO 2808, ISO 2360;

Common standards for impact resistance testing are: ASTM D2794, ISO 6272, GB/T 20624, JIS K5600
