Basic knowledge of water-based paint In order to provide product development support to a wide range of waterborne coating formulation technicians and waterborne coatings sales personnel, we hav collected and summarized a large number of domestic and international market trends and technical points. Visit our waterborne coatings knowledge base and you can see all of our formulation techniques and market analysis. Classification and characteristics of waterborne coatings: Waterborne coatings are called waterborne coatings or waterbased coatings.also known as water-based coatings. Aqueous coatings for wood finishing have a variety of classification methods, which are commonly classified by appearance, use, construction and curing methods, emulsion type, chemical structure, and equipmen methods. The most important ingredients of waterborne wood lacquers are the emulsions and the types of resins that make up the emulsion. The scientific method is to classify the chemical structure of the emulsion. According to the chemical structure, water-based wood lacquer can be divided into: water based acrylic paint, water-based polyurethane paint, waterborne alkyd paint, water-based epoxy paint, sol-gel paint, water-based light-curing paint.

Future development of waterborne paint: In foreign countries, the application of waterborne paint is very wide, especially in the application of home decoration is very mature. In domestic already many enterprises are used at inside ark besmear, cane implement besmear is installed wait With the development of waterborne paint technology, waterborne paint will become a very important paint in furniture coating field. Conclusion: furniture manufacturing will face three trends in the future Environmental protection, environmental protection requirements will be increasingly high. Especially for export orders, merely meeting the requirements of national standards can no longer meet the requirements of customers. High efficiency, high efficiency of production, is one of the most stressed competitiveness of every enterprise. The shortage of labor force forces furniture manufacturing enterprises to improve the automation and assembly line operation of furniture manufacturing. Low cost, as the aggravate of competition, the profit of furniture manufacturing will be lower and lower, this asks manufacturing company should be good at using. New varieties and new technologies enable enterprises to effectively control the overall manufacturing cost.  Sinograce Chemical produces water based coating,Water-based glue, polyurethane coating , Acrylic solution .   visit us sinograce chemical: https://www.sinogracechem.com   Get a Quote Now :sales@sinogracechem.com   Telephone           :+86 0551 63459511

Application of water-based paint coating technology The Paint coating With water-based solvent: non-toxic, non-irritating, environmentally friendly, in line with modern people's fashion taste, convenient construction, good flexibility of paint film. Paint dilution and master the viscosity of the construction directly mixed with water. Advantages of water-based paint: One of the most environmentally friendly paint varieties Extremely convenient for construction Fast drying time, high construction efficiency The activation phase is longer Paint film dry, no smell Disadvantages of water-based paint: The paint film is thinner than solvent - based paint with low fullness Hardness is relatively low solvent - based coatings Common process of water-based paint: Water-based bottom, water surface Water-based bottom, oily surface, etc Common construction method of water - based paint: Mainly manual spraying Precautions for waterborne paint coating: Water-based paint is a kind of natural drying coating: construction of air temperature, relative humidity environment directly affects the drying speed, usually meet with temperature under 10 ℃, relative humidity is over 85%, please don't construction Waterborne, waterborne paint bottom, absolutely to make it fully dry, before coated with PU, NC and other oil-based coating When oily coating is done, water is general cannot do a face. It is difficult for waterborne coatings to adhere to the surface of oily coatings, which will eventually lead to weak adhesion, separation and other coating defects. (it refers to the characteristics of water-based coatings in the market at the present stage.) Coating variety collocation construction technology: in the process of coating construction, there are different requirements for different coating effects. A reasonable, appropriate coating variety collocation process, that can improve the coating effect, reduce the cost of coating, and can improve work efficiency Sinograce Chemical produces water based coating,Water-based glue, polyurethane coating , Acrylic solution .          visit us sinograce chemical: https://www.sinogracechem.com          Get a Quote Now :sales@sinogracechem.com          Telephone           :+86 0551 63459511

Abstract: Reducing the shrinkage of water-based paint film is focused on prevention,designing a rational paint formulation,controlling the paint manufacturing process, and strictly controlling the detection of paint materials, which can reduce the chance of shrinkage. Shrinkage holes have been caused, and it is usually difficult to completely solve them. It is necessary to control the degree of shrinkage holes by internal and external factors. Prevention of shrinkage cavity in water-based paint film 1) Choose a good compatibility defoamer to reduce the chance of shrinkage The prevention and solution of the problem of shrinkage of coatings focuses on controlling the raw materials, production formula and production process of the coatings to ensure the normal production and construction of the coatings. The defoaming agent is used to remove bubbles during the production process of the coatings. The construction process suppresses the generation of bubbles and breaks the bubbles. Release the bubble content air. This is the positive effect of the defoaming agent. The negative effect is to reduce the gloss of the coating film and the poor dispersion of the defoaming agent to form shrinkage cavities. The defoaming agent is a low surface tension material which is insoluble in the system. The dispersing agent with good dispersibility and compatibility can be used to minimize the damage of the shrinkage cavity, and the defoaming agent with good dispersibility and compatibility is in the coating system. It is easy to disperse, the size of the dispersed droplets is suitable, and the defoaming agent in the system is not easy to aggregate into large defoamer droplets. 2) Hydrophobic surface active dispersant used in formula production In the production of paints, raw materials and fillers are often contaminated. The ordinary hydrophilic dispersant is used to grind the surface of the paint slurry to suspend fine oil beads. In severe cases, the flocculent oil powder hybrids will float. The oil powder mixture with fine low surface tension exists inside the paint produced by using such polluted powder, and the construction shrinkage hole is difficult to control. The use of a hydrophobic surfactant-dispersing dispersant and a molecular-grade or non-mineral oil-based defoaming agent ensures the emulsification and dispersion of the oil-contaminated powder. The system has strong tolerance to raw materials and has the potential to prevent shrinkage. Reduce the occurrence of shrinkage cavities.
