Water-based wood paint is a dispersion of water and diluent paint, and commonly used solvent-based paint is different from the formula system is a more complex system. Formulation design, not only to pay attention to the type of polymer, emulsion and dispersion properties, but also a reasonable choice of various additives and taking into account the interaction between the various components of a ...
Factors affecting the curing speed are the main types of paint, coating thickness, curing methods, curing conditions, curing equipment and specific curing procedures. 1.The type of paint Under the same curing conditions, the type of paint is different, the curing speed is very different. Generally speaking, the volatile paint curing fast, oily paint curing is slow. Polymeric paint is very dif...
1. acrylic water-based paint The use of acrylic emulsion as the main component, the main feature is good adhesion, will not deepen the color of wood, but the wear resistance and chemical resistance is poor, the film hardness is soft, fullness is poor, comprehensive performance in general, film Good construction is easy to produce defects. It is suitable for water-based wood primer, matte finish. B...

Waterborne polyurethanes are mostly milky white. The whole process of waterborne polyurethane can be divided into two stages. The first stage is pre-stepwise polymerization, that is, the oligomeric diol, the chain extender, the water-based monomer and the diisocyanate are progressively polymerized through the solution to produce an aqueous polyurethane prepolymer having a molecular mass of the ord...
The exterior wall stone paint of the building is really natural, after the paint is dry,it is like a real stone, and the colors are warm and natural, and the color is fresh and nice. Perhaps a lot of friends, for this anti-stone coating is not very understanding, so,will inevitably feel very strange, then this material really have these advantages? In fact, this anti-stone coating not only has the...
Analysis on the application of waterborne polyurethane (WPU) in coatings Waterborne polyurethane is used in water based wood coatings, which is expected to obtain excellent film hardness, heat resistance and dielectric properties, and good film-forming properties. The higher the degree of microphase separation of aqueous polyurethane,the greater the difference of softening temperature, the better ...
Colorful paint is mainly used in imitation stone effect, so also known as liquid stone and the horizon exterior paint.is composed of incompatible two-phase components, one of the dispersion medium for the continuous phase, the other phase for the dispersed phase. Painting, through a one-time spray, you can get luxury, beautiful, colorful patterns. The pattern formed by the one-time spraying is com...
1.Energy conservation: Water in water multicolor coating, pure water-based formula, excellent raw material technology.Granite stone, depending on nature, the development of powerful resources have some damage to the ecological. Water covered with colorful paint to solve this problem, and decorative curtain wall color can be artificially controlled, energy saving and environmental protection,commen...
Water-in-water multi-color paint spray guns to use most of the spray, for the operation, but also because of the improper use of the gun caused by uneven distribution of the coating,the following together to see how to solve it. The smaller the gun distance, the greater the pressure of the spray, the greater the impact of the product by the pressure of the water, water-in-watercolorful paint coati...
water-based resin | water-based industrial coating (a) water paint common problems Water based paint common problem: bubble - big bubble Large bubbles are large, visible bubbles that are visible to the naked eye. Bulk bubbles generally occur during the production or application of water-based paints. Possible solutions: 1. Use appropriate defoaming agents In the process of producing water-based pa...
Phenomenon : Part of the water-based paint film from the primer uplift, which contains gas or liquid, showed uneven distribution. Cause 1.When the water-based paint is applied, the dry water-based paint film is exposed to rain. 2.Apply a water-based paint primer to the wet substrate. 3.Water - based paint film is affected by acid - base and heat. Amelioration 1.Considering the gas phase conditions...
Phenomenon: Wood coating water - based varnish after the grain fuzzy, grain color and luster differ, failed to retain the original style of wood. cause 1.Transparent putty transparency is poor or scraping too thick, reduce the clarity of wood grain. 2.Water-based paint storage time is too long, pigment precipitation, on the shallow under the deep operation without mixing evenly, coating film thick...
Common problem of lacquer of waterborne woodwork: varnish besmear film is not level off, burnish is not even Phenomenon : Wood is filled with putty hole processing, after sealing the bottom, coating brush varnish, coating film flatness is low, luster is not uniform. Cause : Hole putty poor quality, loose, solvent absorption. The wood fiber and pith ray on the wood surface are relatively loose. The...
Water - based wood paint common problems: gloss wood paint uneven luster Phenomenon There is light coating on the wood surface, coating film gloss, some areas of low gloss. Cause The wood fiber and pith ray in cork are loose with the growth of growth rings, the base material infiltrates excessively, the coating film increases the pigment volume concentration due to the decrease of the base ma...
Case study of water-based paint: the quality of water-based paint is unstable Maintaining the stability of waterborne coatings is one of the keys to the success of waterborne coatings manufacturers. This is especially important for manufacturers of industrial waterborne paints. There are many reasons for the unstable quality of water based paint, such as water-based paint process,water-based paint...
