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 forming agents are ...
Character Mineral oil Primer Matte Strong defoaming ability higher price Different product performance differences Large adjustment space Improper selection can cause film defects Influence gloss, flow equality Non-silicone non-oil Various types of coatings, especially in high gloss finishes There are many defoamers on the market, and the choices are very cautious and can be noted in several ways:...
The types and functions of surface control agents include: 1.Improve flow and leveling 2.Reduce friction coefficient and increase slip 3.Enhanced scratch resistance 4.Anti-blocking 5.Enhance the arrangement of matte powder, etc. 6.Special feel, such as softness, etc. 7.Others such as improving the water resistance and stain resistance of the coating film On the one hand, they balance the surface t...
Water - based coating formulation design system - matting agent Matting agents are additives used to control the gloss of waterborne wood coatings to meet the broad needs of mainstream matt paints in today's market.The extinction mechanism of the matting agent can be arranged in an orderly manner on the surface of the coating film, so that the surface of the coating film is uneven, causing the lig...
Wood coating process 1.There are many large holes in the hard wood, putty or hole adding agent to flatten; 2.Apply closing primer after hole filling； 3.If you need to deepen the surface texture of the wood and highlight the wood grain, you can apply the closed primer and apply the water color； 4.After conditioning the wood grain, apply two closed primer； 5.Finish with top coat.

The steel is subjected to different degrees of corrosion conditions in different operating environments. According to the corrosion conditions, the environmental conditions used by the steel are divided into four grades: Steel use environment and corrosion conditions Steel use environment and corrosion conditions Definition Performance Requirements Coating Effect Harsh conditions Products used in ...
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...
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...
What parameters of resin determine coating gloss? Question: What parameters of the resin determine the gloss of the film? Some people say that it is solid content, some people say it is OH value. So, what is the most important determinant of gloss? Answer: There are many parameters that determine the gloss of the paint film. The saturation of the resin: that is, its monomer structure, this index d...
1.The cause of a back adhesion： (1)the paste itself anti-viscosity, especially in the wet weather easy to stick back; (2)After the printing is completed, it is packaged without perfect heat treatment; (3)adjust the slurry formula is not appropriate, adding too much transparent slurry easy to cause back adhesion; (4)transport or storage conditions are not good, in high temperature, high humidity co...
One, extinction principle General can be divided into physical extinction and chemical extinction.Physical matting, is the addition of matting agent, so that the coating in the film when the uneven surface, reduce reflection and achieve low gloss. Two, the kind of matting agent Coating common matting agent can be divided into organic matting agent and inorganic matting agent two categories. 1.Orga...
1.Introduction to silicone acrylic emulsion Silicon-acrylic emulsion is a kind of composite emulsion. It is a copolymer emulsion of organosilicone and acrylate.Acrylic resin has many excellent characteristics, such as weather resistance and light resistance, long time under ultraviolet irradiation is not easy to yellow。In addition, it also has flexibility, so it is often used as a leather finishin...
Anhui Sinograce Chemical Co., Ltd Polyurethane condoms, known as condoms, are made of polyurethane condoms, similar to latex condoms. Polyurethane was applied to condom production in Japan, until the emergence of China's Nakagawa 001, which broke Japan's monopoly on the production field. Because the common latex condoms on the market are thicker and polyurethane has good ...
