The Selection of good quality water-based adhesive not only help to improve the production efficiency, but also to protect the appearance of the product quality. Such as widely used in the field of self-adhesive water-based pressure-sensitive adhesive, such as water-based pressure-sensitive adhesive which is widely used in the field of stickers. This adhesive has many advantages, it is particularl...
Waterborne polyurethanes are mostly milky white. The whole process of waterborne polyurethane can be divided into two stages. The first stage is pre-stepwise polymerization, that is, the oligomeric diol, the chain extender, the water-based monomer and the diisocyanate are progressively polymerized through the solution to produce an aqueous polyurethane prepolymer having a molecular mass of the ord...
Some of the traditional glue in the adhesion of a great advantage is good adhesion, and the efficiency is very low, the most important thing is relatively low cost, most are someorganic materials. Relatively speaking,the biggest advantage of water-based adhesive is green, the traditional glue is inorganic materials, so it is not very environmentally friendly, pollution is relatively large, water-b...
Analysis on the application of waterborne polyurethane (WPU) in coatings Waterborne polyurethane is used in water based wood coatings, which is expected to obtain excellent film hardness, heat resistance and dielectric properties, and good film-forming properties. The higher the degree of microphase separation of aqueous polyurethane,the greater the difference of softening temperature, the better ...
Phenomenon: Wood coating water - based varnish after the grain fuzzy, grain color and luster differ, failed to retain the original style of wood. cause 1.Transparent putty transparency is poor or scraping too thick, reduce the clarity of wood grain. 2.Water-based paint storage time is too long, pigment precipitation, on the shallow under the deep operation without mixing evenly, coating film thick...
How to solve the poor adhesion of water-based paint after soaking in water? Problems: water-based acrylic resin, self-drying system,60 ℃ / 120 minutes after the bubble row down into the water, can use fingernail.But after taking out to wait for water to be able again, how should solve? Response: This test method is still very harsh.General water - based resins, acrylic acid, polyurethane or Self-c...
Case study of water-based paint: the quality of water-based paint is unstable Maintaining the stability of waterborne coatings is one of the keys to the success of waterborne coatings manufacturers. This is especially important for manufacturers of industrial waterborne paints. There are many reasons for the unstable quality of water based paint, such as water-based paint process,water-based paint...

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...
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...
