Problem:Some of the materials used in the construction of wood products are plywood and wood chip fiberboard. One of the rubber is the most afraid of water, water paint spray will dissolve the inside of the glue. The effect that USES close lacquer also is not ideal, how should solve? Is it easy to use sinograce chemical raw material solution? thank you . Response:This type of wood is usually ...
Question: how to make water-borne heat-resistant paint and water-borne silver powder paint? Whose resin is better? Can you provide the reference formula? Response: Hello, Mr.Zheng,We have received many similar requests for reference formulations.Industrial coatings are characterized by their complexity.It is water borne anti-rust paint likewise,because use environment and the different that ask, f...
Oil pocket phenomenon in water-based paint Problem: To make furniture with transparent colors, in order to save the craft and achieve the purpose of simple construction. We added water-based Color Concentrate to the topcoat for spraying, and the resulting topcoat contained some oil pockets or other unacceptable "face problems." Reply: Aqueous color concentrates are generally made of metal complexe...
PH adjustment of water-based paint-Ask water character paint expert Question: If the pH value of the water-based paint is not weakly alkaline or the pH value is unstable, what effect will it have in actual use? Thank you! Response: The unstable pH of water-based paints has two main effects on water-based paints.One is that it affects the stability of the filler or paste in the resin because the pH...
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...
Is the black spot on the surface of the water-based paint mildew? Problem: The wooden doors of our company's surface veneer have no black spots before they are painted. After spraying the water-based paint (primer + top coat), black spots appear on the veneer during the natural drying process. I wonder if the water-based paint is mildewed? If the oil-based colorant is used to seal the bottom, will...
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...
Factors Affecting Shrinkage of Waterborne Coating Films In practice, the main causes of shrinkage are as follows: 1. The substrate is contaminated by oil or impurities 2. Apply a paint to the old paint or finish without sanding 3. The interval between constructions of the two paints is too long 4. Too much defoamer in the paint The following focuses on two factors: defoamer and impurity contaminat...

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...

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...
The types and functions of surface control agents include: 1.Improve flow and leveling 2.Reduce friction coefficient and increase slip 3.Enhanced scratch resistance 4.Anti-blocking 5.Enhance the arrangement of matte powder, etc. 6.Special feel, such as softness, etc. 7.Others such as improving the water resistance and stain resistance of the coating film On the one hand, they balance the surface t...
