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 various additives and make a reasonable match in consideration of the interaction between the components.Also select some special additives according to special requirements, and finally form suitable formula.The basic components and functions of water-based wood paint are as follows:

1.polymer emulsion or dispersion: This is the film-forming binder, which determines the main function of the film.
2.Film-forming aid: After the water is volatilized, the emulsion or the dispersion particles are formed into a uniform and dense film, and the film formation property under low temperature conditions is improved.
3.Suppressing agent and defoaming agent: inhibiting the bubbles generated in the paint solution during the production process and causing the generated bubbles to escape from the liquid surface and breaking the bubble.
4.Wetting leveling agent: Improve the wetting property of the paint liquid on the substrate, improve the leveling property, and increase the adhesion of the paint film to the substrate.
5.Rheology additives:provide good fluidity and leveling of the paint, and reduce the defects in the painting process.
6.Surface Control Aid: Improve the performance of the film.
7.Matting agent: regulates the gloss of waterborne wood coating.

8.Preservative: Prevent the paint from becoming moldy during storage.

9.pH adjuster: adjust the pH of the paint to stabilize the paint.

10.Colorants and fillers
11.Special additives

In addition, the formulation is often designed to add a small amount of deionized water to make paint.
