Classification and characteristics of waterborne coatings - waterborne light curing coatings Waterborne light curing coating is a kind of coating classified by curing method. It is a very important kind of coating.In any polymer molecule, a structure in which a reactive group capable of being decomposed by a photoinitiator or a structure capable of being excited by a high-energy radiation to produ...
Formulation design system for waterborne coatings - film forming AIDS The polymer constituting the emulsion or dispersion generally has a glass transition temperature higher than room temperature. In order for the emulsion particles to be well fused into a uniform paint film, it is necessary to reduce the minimum film formation temperature (MFFT) of the crystallization aid.Film form...

Rheological AIDS provide a leveling effect under high shear conditions, allowing the painted fluid to level out as quickly as possible, reducing brush marks and avoiding spatter. However, as the drying time goes by, this leveling effect weakens and the film is fixed, which can prevent the fluid from sagging on the vertical surface. Rheological additives can be divided into high, medium and low she...
Types, characteristics and applications of main rheological AIDS Variety Feature Application Methyl Cellulose The water system is thickened and has high efficiency, but the water resistance is not good, it is easy to be degraded by microorganisms, moldy and smelly, and the thixotropy after thickening with the system is strong, and the leveling property is not good. Generally not used in waterborne...
Waterborne paint formulation design system - pH regulator Waterborne wood coatings may also need to adjust the pH when necessary.Most emulsions or aqueous dispersions have been adjusted to a pH of 8 to 9 when they are produced, eliminating the need for pH adjusters when making paint.If the pH value is different, add 0.05% to 0.1% of the pH adjuster during the paint making process, and adjust the p...
Essence As long as the amount of essence can improve the odor of the paint liquid, the dosage is about 0.05%, and the individual case can be as high as 0.1%. Of course, it can be used. ultraviolet light absorber Indoor water-based wood paint rarely use ultraviolet absorbent, for the use of TDI emulsion or moisture dispersion production of varnish and outdoor paint, especially outdoor white paint h...
To master waterborne wood coatings and coatings, you must be familiar with the characteristics of wood. In this way, we can find the root cause of the problem in the painting process and make the necessary preventive and treatment measures. Wood is a natural fiber material, seen from the cross section of the trunk, it is a uniform material composed of layers of different materials, with many textu...
Due to the chemical composition of the wood and the particularity of the wood fiber, if it is not handled properly, the water-based paint film will be damaged. Wood is composed of cellulose and a small amount of gum, resin (rosin), pigment, tannin and the like. Although the amount of gum, resin, pigment, tannin, etc. is small, it has a large negative impact on the properties of the coating (mainly...
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...
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...
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...
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...
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...
Paint of water-based paint - Waterborne wood paint application process 2 Before using the soft brush, thoroughly soak it in clean water, remove excess water, and do not drip. The enamel paint should only reach half the length of the bristles.Brush as fast as possible, gently and smoothly brush the wood grain, and do not apply it back and forth repeatedly. Because the water-based paint dries quickl...
