In recent years, with the increasing awareness of environmental protection and the importance and legislation of governments in environmental protection, more and more anti-rust paints are turning to water-based.Many foreign customers have begun to demand waterborne anti-corrosive paints for domestic suppliers. After sinograce chemical successfully launched our water-based anti-corrosive paint|wat...
How to deal with the surface of water-based anti-rust paint before painting As the saying goes, "seven-point paint three-point paint." The correct handling of the substrate can have a major impact on the performance of the coating. Waterborne anti-corrosive paint is no exception. During the processing, transportation and storage of the workpiece, the surface often has the moldi...
The internal structure of waterborne acrylic emulsion particles will affect several aspects of waterborne paint formulations.According to the order in which the effects are affected, the phase structure will first affect the selection and addition of the filming aid.Different phases have different hydrophilic/lipophilic characteristics, and the oleophilic properties of various coalescents are diff...
Water - based acrylic emulsion formulation needs to be considered: water - based acrylic resin composition The choice of emulsion raw materials is the most important decision for engineers when formulating aqueous paint formulations.The main properties of the coating are determined by the resin.A wide variety of water-based acrylate emulsions, including polystyrene-acrylate emulsions, are on the m...
Adding certain kinds and dosages of substrate wetting agent and adhesion promoter to the transparent base formulation helps to improve the adhesion of the paint film; the type and quality of the color paste are not only related to the phase of the color paste and the transparent base. Capacity also has a certain influence on the adhesion of the paint film. The thickness of the paint film, the dryi...
Sinograce Chemical - Jingangtai rafting trip On August 17th, Sinograce Chemical Marketing Center carried out the second quarter group building activities of the Rapids Warriors, blue sky and white clouds, green mountains and green waters, riding a rubber boat, leaping in the cool water, Sometimes light as a swallow, Now and then it gallops like a tiger, the event The thrills not only make the...
The adhesion of the paint film is caused by the mutual attraction between the paint and the polar groups on the surface of the coated substrate, and the mutual attraction between the polar groups is based on the premise that the paint is well wetted on the surface of the coated substrate.Since the wet condition of the coating on the surface of the coated substrate depends on the surface tension of...
Cohesion and thermal expansion coefficient of paint film The force caused by the cohesion of molecules of the same substance is called cohesion.The more cohesive the coating, the worse the adhesion.In the drying process of paint, with the increase of solvent volatilization and crosslinking degree, the cohesion between film forming material molecules increases, the film produces shrinkage phenomeno...
From the viewpoints of molecular structure, molecular polarity and molecular interaction force, the adhesion of the paint film results from the polar group orientation of the polymer molecules in the coating, and its polar group with the polar molecules on the surface of the coated object. The mutual attraction between each other.Only when the polar phase of the two is adapted to obtain a good adh...
Adhesion type and adhesion property of paint film on substrate The adhesion of the paint film to the substrate is divided into two types: mechanical adhesion and chemical attachment.Mechanical adhesion depends on the properties of the coated sheet (roughness, porosity) and the strength of the formed film; chemical adhesion refers to the mutual attraction of the paint film molecules and the plate m...
