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 of water-based varnish is obvious. Answer： Although it is a water-based paint, the film is hydrophobic. Brush the water-based paint on the water-repellent paint mold to remove oil due to water wetting. White paint does not have this phenomenon, because white paint is relatively thick surface. Solutions include: 1.Reduce the surface tension to a certain extent to reduce the smoothness of the film surface. 2.Do not use fluorinated surfactants. 3.Try to use a surfactant with good hydrophilic properties. 4.Pay attention to the HLB value Sinograce chemical Specializes in producing waterborne coatings, waterborne wood lacquer,topcoat ,primer etc. To learn more, please click here visit us sinograce chemical: https://www.sinogracechem.com Get a Quote Now :sales@sinogracechem.com Telephone :+86 0551 63459511

Leveling and rheological properties of waterborne coatings Problem: water borne white coating wants to have certain rheological already, want to maintain just right leveling sex again, how to do？ Response： This problem is one of the characteristics and technical characteristics of water based paint ，In principle, it is mainly the relationship between equilibrium viscosity and rheology (plasticity). In practice, the main solution is to choose the right thickener.Of course, the solid content of coating itself is also one of adjustable variables.In addition, the drying speed of the coating is another factor affecting the final leveling. The specific method can refer to the water - based formula library of Sinograce Chemical.

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 relationship .Usually because the film is thin(about 20 microns) .Basically, the water in the paint film evaporates almost before the temperature reaches 100C,and even if the temperature reaches more than 100C,Because the resin has not fully crosslinked, strong plasticity, can ensure the migration of water vapor,so usually the evaporation of water will not cause the bubble in the paint film . This point, water based paint and solvent-based paint no difference, many solvent-based paint baking has exceeded the boiling point of the solvent, but the bubble is the same principle to avoid . Of course,When the film thickness increases, this problem will be one of the factors considered in the process, which can be solved by adjusting the baking time and heating speed .

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 understand the reason of water - based acrylic paint adhesion .The readhesion of waterborne acrylic paint is due to the increase of rheological properties of linear thermo plasticpolymer at higher transition temperature than glass.The solution of water - based acrylic paint back adhesion can be considered from several perspectives. 1.High Tg acrylic resin was added and fast volatile film forming agent was used 2. Use self-crosslinking acrylic resin as far as possible 3.Choose acrylic emulsion with smaller particle size as far as possible 4.Add PUD. PUD has a certain thermosetting property and can reduce thermoplasticity 5.Add the wax emulsion. Wax emulsion can form wax film on the coating surface and reduce the surface viscosity 6.If the resin system contains carboxyl group, a little metal salt such as zinc or oxide can be added to play the role of ion crosslinking 7.Add filler with smaller particle size For more information about waterborne coatings, you can also visit the Sinograce Chemical industry news waterborne coatings repository, and the recipes in our waterborne coatings repository.Or ask questions directly to us through our water-based paint expert column. To promote waterborne paint in China is the goal of Sinograce Chemical. I hope you found the above explanation helpful.
