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 furni...
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 ...
Classification and characteristics of waterborne coatings - Waterborne acrylic coatings The emulsifier that USES when polymerization can be anionic, also can be nonionic or cationic, corresponding latex and the lacquer that make also can call anionic, nonionic or cationic. Acrylic waterborne wood lacquer is a variety of applications that have been used earlier and are still in large quantities. Si...
Classification and characteristics of waterborne coatings - waterborne polyurethane coatings Polyurethane is a general term for a class of macromolecular compounds having a carbamate structure in a molecular structure, and is usually produced by a polyaddition reaction of a diisocyanate and a polyol. In view of the variety of isocyanates and polyols, the resulting polyurethanes can range from soft...
Classification and characteristics of water-based coatings - water-based alkyd paints The vegetable oil is reacted with an acid anhydride after alcoholysis to form an alkyd resin, and the content of the hydrophilic group can be increased to form a water-soluble or water-dispersible resin.Water-soluble water-based alkyds are quite transparent in appearance but have color,The alkyd emulsion was brow...
Sol-gel coating Classification and characteristics of waterborne coatings - sol /gel coatings Sol-Gel coatings is a new type of coating that has received special attention in recent years. The progress of inorganic nanopowders has promoted the development of sol-gel coatings.The main component of the sol-gel coating is an organic resin and a silane compound, and the silane is hydrolyzed to form a ...
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...
The basic principles of the following waterborne wood paint formulation design The amount of the emulsion or the aqueous dispersion is as much as possible because the material of the emulsion is mainly composed of a polymer material which is a backbone for ensuring the final film properties; The additive are as few as possible, and they can be used without being used. These additive will be presen...
Water - based coating formulation design system Waterborne coatings, including waterborne wood lacquers, are water-based dispersions and diluents. Unlike conventional solvent-based coatings, the formulation system is a more complex system.When formulating, not only the type of polymer, the properties of the emulsion and the dispersion are concerned. It is also necessary to rationally select variou...
The film-forming aids for waterborne wood coatings are generally alcohol ether type solvents. The most commonly used filming aids such as diethanol ethers, propylene glycol ethers and N-methylpyrrolidone have high and low boiling points.Water-based wood coatings in the summer construction, the water volatilization is faster, that is, the surface is relatively fast, some of the moisture may be encl...
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...
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...
Types and characteristics of main extinction agents Types Features Organic matting agent (synthetic wax) It can not only extinction, but also increase the surface smoothness, enhanced hand feeling and anti-settling property of the coating film. However, such matting agents often affect the transparency of the coating film and even affect the interlayer adhesion of the coating film. Inorganic matti...
Water-based coating formulation design system - preservative Water-based wood coatings are water-based systems that are easier to bring into bacteria during production and are more susceptible to microbial degradation during storage. Therefore, the type and amount of preservatives should be properly added during formulation to prevent system and coating corruption.From the perspective of environme...
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...
