Why is film leveling so important?

Coatings play an important role in industrial applications, but during the construction process, a rough wet paint film is usually formed, which needs to go through the leveling process to achieve good surface quality. The flatness of the paint film is crucial to the painting process, because it directly affects the final quality and appearance of the painting. Poor film levelling can lead to a variety of problems, such as brush marks when brushed, orange peel-like surface textures when sprayed,...

Viscosity: The microscopic forces inside the liquid shape the macroscopic properties

Viscosity, for most people, may be a relatively unfamiliar word, but it plays a very important role in our daily lives. Viscosity is a key property of liquids, which describes how the interaction between molecules impedes the relative motion of the molecules under the action of external forces, thus affecting the flow properties of the liquid. The understanding and determination of this property is crucial for a wide range of fields, from chemicals to coating production. In this article,...

Concept and determination method of non-volatile content

In the coatings industry, quality control is one of the key factors to ensure product performance and stability. One of the important quality parameters is the non-volatile content, which reflects the proportion of non-volatile components in the paint. In this paper, the concept of nonvolatile content, its determination method and its importance in coating production will be discussed in depth. The concept of non-volatile content Non-volatile refers to the material remaining after volatilization of the paint under specific test conditions. There...

Reasons and countermeasures of paint film retraction

In the process of coating construction, paint film retraction is a common but troublesome problem. It will cause the coating to be uneven during the coating process, ultimately affecting the quality and appearance of the coating film. In this article, we will explore the causes of paint film retraction and how to effectively address this challenge. The flatness of coatings is usually affected by surface tension. Surface tension is a manifestation of the force exerted on the surface of the...

introduction Transparency is a crucial property in paint production, reflecting the ability of a substance to penetrate light. Transparency not only directly affects the appearance and gloss of coating products, but also its performance and quality. In this paper, the importance of transparency in coating production and the detection method of transparency will be discussed in depth. The transparency of coatings and its detection method The importance of transparency Transparency has a profound impact on the quality and performance of coating products, and...

Varnish color Determination of paint color

introduction In modern society, color is everywhere. It not only endows objects with beauty, but also conveys information and emotions. In the coating industry, color is one of the key characteristics of the product, which not only reflects the composition and purity of the coating, but also directly affects the film formation performance and use range of the product. This article will delve into the importance of color in the coating industry and the two commonly used color determination methods:...

Principle and method of coating density determination

In the coatings industry, density is a key property, which is not only used for quality control, but can also help optimize the performance of coatings. By measuring the density of the paint, we can understand the accuracy of the coating's ingredients, quality stability, and the area that the paint can cover per unit volume during construction. This paper will discuss the importance of density in coating industry and the principle and method of density measurement. Importance of density Density is...
