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...
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...
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...

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...
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...
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...
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...
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.
