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 ...
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...
Problem：I have not done waterborne polyurethane, the waterborne paint is a rookie .I have never done water - based, water -based is a rookie，I wonder if waterborne polyurethane also needs curing agent? If you want to use it, what is the ratio?Because of the presence of water, is it possible to go back and consume the curing agent?And I want to use this to make the electroplated silver, is it ok? R...
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...
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...
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...
Classification and characteristics of waterborne coatings - Waterborne acrylic coatings The emulsifier that USES when polymerization can be anionic, also can be nonionic or cationic, corresponding latex and the lacquer that make also can call anionic, nonionic or cationic. Acrylic waterborne wood lacquer is a variety of applications that have been used earlier and are still in large quantities. Si...
Classification and characteristics of water-based coatings - water-based alkyd paints The vegetable oil is reacted with an acid anhydride after alcoholysis to form an alkyd resin, and the content of the hydrophilic group can be increased to form a water-soluble or water-dispersible resin.Water-soluble water-based alkyds are quite transparent in appearance but have color,The alkyd emulsion was brow...
Classification and characteristics of waterborne coatings - waterborne light curing coatings Waterborne light curing coating is a kind of coating classified by curing method. It is a very important kind of coating.In any polymer molecule, a structure in which a reactive group capable of being decomposed by a photoinitiator or a structure capable of being excited by a high-energy radiation to produ...
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...

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...
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...
Types and characteristics of main extinction agents Types Features Organic matting agent (synthetic wax) It can not only extinction, but also increase the surface smoothness, enhanced hand feeling and anti-settling property of the coating film. However, such matting agents often affect the transparency of the coating film and even affect the interlayer adhesion of the coating film. Inorganic matti...
