Classification of solvent-based inks 1. According to the chemical properties of solvents, we divide them into multiple categories, including ketones, ethers, esters, alcohols (monohydric alcohols – aliphatic, alicyclic and glycols), and hydrocarbons Compounds (aliphatic, aromatic, cycloalkanes). Within these categories, we can further distinguish between polar solvents, non-polar solvents, active solvents, inert solvents and diluents. Polar…
Application of defoaming agents in environmentally friendly water-based inks In recent years, with the need to build an environmentally friendly society and the improvement of people’s living standards, the use of various packaging materials has increased significantly and become increasingly exquisite. The demand for water-based coatings has increased significantly, especially the application of water-based inks…
Selection of defoaming agents in water-based paints In water-based paint, it is easy to foam. Because the high surface tension of water (70+) must be blended into the low surface tension of paint (around 30), low surface energy materials are essential. Defoaming agents are a carefully selected class of materials that generally: ①. The surface…
Is paintdefoamer really the indispensable core of paint foaming? Everyone is familiar with the word coating. The traditional Chinese name for “coating” is paint. Coating refers to a type of liquid or solid that is coated on the surface of an object and can form a thin film under certain conditions to provide protection, decoration…
Factors affecting defoaming agents in coating formulations Factor 1: Surface tension The surface tension of the paint has a great influence on the defoaming agent. The surface tension of the defoaming agent must be lower than the surface tension of the paint, otherwise it will not have defoaming and foam suppression effects. The surface tension…
Tips for using paint defoamer Precautions for the use of coating defoaming agents are something that every merchant who purchases and uses coating defoaming agents must understand. When using coating defoaming agents without understanding, counterproductive effects will often occur, such as: ①Why can’t the bubbles disappear even after adding so much? ② When testing the…
How to add defoaming agent for coating industry? With the continuous development of the coating industry, the application requirements for defoaming agents are becoming higher and higher. Foam problems can occur during the coating production process, thus affecting product quality and yield. For some products that require the use of large amounts of defoaming agents,…
Are mineral oil defoamer water-based or oil-based? Mineral oil defoamer cannot be used in many industries because it is incompatible with many water-based systems and has poor water solubility. However, some friends asked me why there is a water-based mineral oil defoamer on the market and whether it is It has good compatibility with defoamer…
