Asked by water-based paint experts: water-based wood lacquer wood grain display is not clear enough Question: Our company is now doing the first coat of wood lacquer and tried a water-based resin (polyurethane). and there is no problem with the adhesion.The current problem is that after adding color essence, it is applied to the floor and the wood grain display is not clear enough. The amount of t...
Asked by water-based paint experts: water-based paints appear flocculated in the production process Problem: Our company produced a batch of waterborne paint last week. The formula remains unchanged. After the completion of production, the coating appears a mass flocculent,it is difficult to remove the filtration, the quality of waterborne coating is reduced. What is the cause? What method c...
Common problems with water-based paint: the coating contains bubbles and degassing Phenomenon: During the production of waterborne coating, it is found that the coating contains bubbles after thickening.The bubble volume is big bubble, the volume is small bubble, This kind of phenomenon often happens in paint of equal thickness thick pulp of elastic drawing. Bubble may cause pinhole or prickly hea...
Ask the water-based paint expert -water-based glass paint appears prickly heat when baking Problem: I use water-based acrylic and amino resin to make the glass paint when baking prickly heat. The details are as follows: Temperature: 80 degrees Time: 2 minutes It was already smooth when it was put into the oven Flash dry for 10 minutes Has been changed to defoamer, leveling agent, solvent, no effec...
How to solve the water - based acrylic paint back adhesion problem? - ask a water-based paint expert Problem: How to solve the water - based acrylic paint back adhesion problem? Water - based acrylic paint back adhesion is a problem often encountered by water - based paint formulators.In order to solve the problem of water - based acrylic paint adhesion, we must fundamentally unders...
Common problems of water based paint: causes of shrinkage and solutions Shrinkage, known as cratering, is a common problem with water-based paints。The main cause of shrinkage cavity is impurities in water-based paint. In particular, there is oil in the area where the shrinkage cavity occurs, making the area unable to be wetted.In practical operation, the main causes of shrinkage cavity are as foll...
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 ...
Formation of shrinkage cavity problems in waterborne coatings The surface defects of the coating film are mainly depressions, pinholes, and the edges or thick edges of the corners. There are two kinds of cases on the surface of the coating film, one is a circular depression, and a hexagonal polygonal depression. The depression on the surface of the coating film is caused by the surface tension gra...
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...
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...
The basic principles of the following waterborne wood paint formulation design The amount of the emulsion or the aqueous dispersion is as much as possible because the material of the emulsion is mainly composed of a polymer material which is a backbone for ensuring the final film properties; The additive are as few as possible, and they can be used without being used. These additive will be presen...
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...
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...
