The application of alternative solvent based products in various fields. Waterborne polyurethane, as a representative, can be widely used in coatings, adhesives, fabric coatings and finishing agents, leather finishing agents, paper surface treatment agents, and fiber surface treatment agents.Waterbo

Compared with traditional solvent based coatings, water-based coatings have the advantages of low price, safe use, saving resources and energy, reducing environmental pollution and public hazards, and have become the main direction of the current development of the coating industry. Waterborne acryl

Waterborne acrylic resin includes acrylic resin lotion, acrylic resin aqueous dispersion (also called water dilutable acrylic acid) and acrylic resin aqueous solution.Compared with traditional solvent based coatings, water-based coatings have the advantages of low price, safe use, saving resources a

The characteristics of defoaming agents for landfill leachate are as follows:1. The defoaming and defoaming effect of leachate treatment is significant, and the dosage is small, which will not affect the properties of the foaming system itself;2. It can remove various forms of foam, such as biologic

1. Insoluble or insoluble in foam solutionIn order to destroy foam, defoamer should be concentrated on foam film. For the state of defoaming agent, it should be concentrated and aggregated in an instant, and for the state of foam suppression, it should always be maintained in this state. Therefore,

Accidents can also occur during the use of defoamers, and oil slicks are common. What is the reason for the oil slick of defoamer?This is due to its own materialDefoaming agents are mostly mixtures, mainly carriers or additives of defoaming agents. There are many types of defoamers, such as silicone

1. Active ingredient: The main ingredient of silicone defoamers is linear polysiloxanes (also known as silicone oil) that can maintain liquids at room temperature as active agents. The main types of polysiloxanes are: polydimethylsiloxane, fluorosiloxane, and ethylene glycol siloxane.Silicone oil is

Various high-speed mixers need to be used in the coating manufacturing process, such as three-roller machine, sand mill and ball mill. Various methods used for coating, such as air spraying, airless spraying, roller coating, flow coating and spray coating. In these processes, the free energy of the

Leveling agent is a commonly used coating agent, which can promote the formation of a flat, smooth and uniform coating film during the drying process. A class of substances that can effectively reduce the surface tension of the finishing liquid and improve its leveling and uniformity. It can improve
