Question: Dear expert, I am now eager to develop a new water-based paint mainly for wood. The problem that needs to be solved urgently is the drying time of water-based paint. I want his dry time to be in 30 seconds, can you achieve excuse me, excuse me be colophony its key effect. Response: Hello, the dry time of water - based paint has two concepts commonly."Surface dryness" refers to the basic ...
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...
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...
The relationship between film formation and MFFT of waterborne coatings This week, Mr. Li asked us three questions through our questioning water-based paint expert column. This is the second problem: Problem: Film formation above MFFT, no film formation below MFFT, what happens during above or below the MFFT, resulting in film formation? Above MFFT, the emulsion particles are soft and hard below. ...
Wood closed primer formula solves the outstanding problem of wood grain Wood bulges and deforms or wood grain protuberant,It is a common problem in wood painting. We discussed the causes and solutions of this problem in this year's topic.In the article on wood grain protrusions - water-based paints, we recommend three technical solutions: 1. Use a saturated coating of 3-4% binder solids....
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...
Application of water-based paint coating technology The Paint coating With water-based solvent: non-toxic, non-irritating, environmentally friendly, in line with modern people's fashion taste, convenient construction, good flexibility of paint film. Paint dilution and master the viscosity of the construction directly mixed with water. Advantages of water-based paint: One of the most environmentall...
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 ...
Sol-gel coating Classification and characteristics of waterborne coatings - sol /gel coatings Sol-Gel coatings is a new type of coating that has received special attention in recent years. The progress of inorganic nanopowders has promoted the development of sol-gel coatings.The main component of the sol-gel coating is an organic resin and a silane compound, and the silane is hydrolyzed to form a ...
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...
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...
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...
