What are the classifications of Antistatic Agents? -Customized Antistatic Solutions from NANJING REBORN
Antistatic agents are becoming increasingly necessary to address issues such as electrostatic adsorption in plastic, short circuits, and electrostatic discharge in electronics. According to different usage methods, antistatic agents can be divided into two categories: internal additives and exter...Read more -
A PROTECTOR FOR POLYMER: UV ABSORBER
The molecular structure of UV absorbers usually contains conjugated double bonds or aromatic rings, which can absorb ultraviolet rays of specific wavelengths (mainly UVA and UVB). When ultraviolet rays irradiate the absorbent molecules, the electrons in the molecules transition from the ground s...Read more -
Classification and usage points of coating leveling agents
Leveling agents used in coatings are generally classified into mixed solvents, acrylic acid, silicone, fluorocarbon polymers and cellulose acetate. Due to its low surface tension characteristics, leveling agents can not only help the coating to level, but may also cause side effects. During use, ...Read more -
What is leveling property of coatings?
Definition of leveling The leveling property of a coating is described as the ability of the coating to flow after application, thereby maximizing the elimination of any surface unevenness caused by the application process. Specifically, after the coating is applied, there is a process of flow an...Read more -
What affects the defoaming of coatings?
Defoaming is the ability of a coating to eliminate the foam generated during the production and coating process. Defoamers are a type of additive used to reduce the foam generated during the production and/or application of coatings. So what factors affect the defoaming of coatings? 1. Surface te...Read more -
Types of UV absorbers
Introduction of UV absorber Sunlight contains a lot of ultraviolet light that is harmful to colored objects. Its wavelength is about 290~460nm. These harmful ultraviolet rays cause the color molecules to decompose and fade through chemical oxidation-reduction reactions. The use of ultraviolet abs...Read more -
Coating antioxidant
Introduction Antioxidants (or heat stabilizers) are additives used to inhibit or delay the degradation of polymers due to oxygen or ozone in the atmosphere. They are the most widely used additives in polymer materials. Coatings will undergo thermal oxidation degradation after being baked at high ...Read more -
Skin care cleaning surfactant APG (Alkyl Polyglycoside)
APG, short for Alkyl Polyglycoside, is a nonionic surfactant. Simply put, it is like a magical “cleaning magician” that can make cleaning products work superbly. It’s a rising star in skin care ingredients. From nature The raw materials of APG are all from nature. It is mainly ...Read more -
Development of dispersants (2)
In last article, we introduced the emergence of dispersants, some mechanisms and functions of dispersants. In this passage, we will explore the types of dispersants in different periods with the development history of dispersants. Traditional low molecular weight wetting and dispersing agent The ...Read more -
Development of dispersants (1)
Dispersants are surface additives used to stabilize solid particles in media such as adhesives, paints, plastics and plastic blends. In the past, coatings basically did not need dispersants. Systems such as alkyd and nitro paint did not need dispersants. Dispersants did not appear until acrylic r...Read more -
Function and mechanism of adhesion promoter
Function and mechanism of adhesion promoter Generally adhesion promoters have four modes of action. Each has a different function and mechanism. Function Mechanism Improve mechanical bonding By improving the permeability and wettability of the coating to the substrate, the coating can...Read more -
What is adhesion promoter?
Before understanding adhesion promoters, we must first understand what adhesion is. Adhesion: The phenomenon of adhesion between a solid surface and the interface of another material through molecular forces. The coating film and the substrate can be combined together through mechanical bonding, ...Read more
