Baking performance of water-based glass paint - ask an expert for water-based paint. Question: I would like to ask about the water-based glass baking paint .Water has a boiling point of 100 degrees Celsius, so if you bake it at 140 degrees, it won't boil and bubble up and destroy the film. Right? Response: Water - based paint to balance the evaporation of water and film curing between the relation...
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...
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 ...
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...
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 ...
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...

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...
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:...
