Is the water-based wood paint film as hard as possible? In the market of waterborne wood lacquers, hardness is one of the most concerned indicators for many Chinese waterborne paint developers and users.In the traditional concept, the harder the paint film, the better. There are often customer consultations for ways to get the paint film to 2H or even 3H.Although waterborne wood lacquers have impr...
Filming aids in waterborne coatings Problem : Why do you need to add filming aids to one-component waterborne coatings? The emulsion alone does not form a film. Filming aids are added to form a film. Why does the film-forming auxiliary volatilize, which is still a complete film, and is different from a film without a filming aid? Why can't a single emulsion be fused by water to produce a capillary...
Waterborne two-component paint seeds and loss of light - ask water-based paint experts Question: Hello! I have two problems with the double-surface water-based topcoat. One is that when the film is thick, it is easy to produce rash [related to defoaming agent or related to water and curing agent to produce CO2?]. One is a double component. After mixing for 2 hours, it will lose light. What is the ...
The relationship between film formation and MFFT of waterborne coatings This week, Mr. Li asked us three questions through our questioning water-based paint expert column. This is the second problem: Problem: Film formation above MFFT, no film formation below MFFT, what happens during above or below the MFFT, resulting in film formation? Above MFFT, the emulsion particles are soft and hard below. ...
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 sh...

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 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...
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...
In the formulation of waterborne wood lacquer topcoats, the binder is a key component in forming the film and determining the properties of the film. The binder, ie the polymer emulsion, dispersion or hybrid, accounts for more than 80%, preferably more than 90%.Since the solid content of the emulsion, especially the aqueous dispersion is relatively low (the aqueous dispersion is generally 30% to 3...
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...

Defoamer is one of the most difficult additives in waterborne wood coatings to control the balance between defoaming and leveling.The paint liquid will generate bubbles during the application due to agitation .If the bubbles present in the paint are not removed in time, the film will dry and form an unacceptable flaw.The paint also produces air bubbles during production, pumping and filling. Defoa...
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:...
Formulation design system for water based coatings - wetting leveling agent The wetting leveling agent can effectively reduce the surface tension of the system and significantly improve the construction effect of the waterborne wood lacquer.After the addition of the wetting leveling agent, the wetting property and permeability of the paint increase, the leveling property of the paint liquid is imp...
