Water-based wood paint runs off oil---Ask a water paint expert Question: Waterborne wood lacquer should run oil to a rainy day only, or brush one day, also can run oil when waiting for the 2nd day to brush again, did especially ugly later . Water-based white paint does not have this problem. The problem ofwater-based varnish is obvious. Answer： Although it is a water-based paint, the film is hydro...
April 12, 2019, the 40-days orange war ended, every partners in this war to pay 100% of the effort, made a different victories,, although the end of the war, but we never give up, the spirit of teamwork will always be maintained, let us move forward.
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...
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. ...
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 ...
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...

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...
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...
Waterborne paint formulation design system - pH regulator Waterborne wood coatings may also need to adjust the pH when necessary.Most emulsions or aqueous dispersions have been adjusted to a pH of 8 to 9 when they are produced, eliminating the need for pH adjusters when making paint.If the pH value is different, add 0.05% to 0.1% of the pH adjuster during the paint making process, and adjust the p...

1.The tool Before using the soft brush, thoroughly soak it in clean water, remove excess water, and do not drip. The enamel paint should only reach half the length of the bristles.Brush as fast as possible, gently and smoothly brush the wood grain, do not apply it back and forth repeatedly, because the water-based paint is fast drying and the opening time is short, so it should be completed as soo...
3.Process variations of different paint types-Waterborne wood paint application process 2 Applying a matt lacquer to the varnish can change the coating to a matte finish, while applying a varnish to a matt lacquer reduces the brightness of the film and does not achieve maximum brightness and transparency. The color paint of waterborne wood lacquer can be divided into two types: coloured coating an...
