Water - based wood paint common problems: gloss wood paint uneven luster Phenomenon There is light coating on the wood surface, coating film gloss, some areas of low gloss. Cause The wood fiber and pith ray in cork are loose with the growth of growth rings, the base material infiltrates excessively, the coating film increases the pigment volume concentration due to the decrease of the base ma...
Asked by water-based paint experts: water-based wood lacquer wood grain display is not clear enough Question: Our company is now doing the first coat of wood lacquer and tried a water-based resin (polyurethane). and there is no problem with the adhesion.The current problem is that after adding color essence, it is applied to the floor and the wood grain display is not clear enough. The amount of t...
Asked by water-based paint experts: water-based paints appear flocculated in the production process Problem: Our company produced a batch of waterborne paint last week. The formula remains unchanged. After the completion of production, the coating appears a mass flocculent,it is difficult to remove the filtration, the quality of waterborne coating is reduced. What is the cause? What method c...
Ask the water-based paint expert -water-based glass paint appears prickly heat when baking Problem: I use water-based acrylic and amino resin to make the glass paint when baking prickly heat. The details are as follows: Temperature: 80 degrees Time: 2 minutes It was already smooth when it was put into the oven Flash dry for 10 minutes Has been changed to defoamer, leveling agent, solvent, no effec...
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 unders...
Wood bumps - Common problems with water paint Wood grain is exposed when broken or damaged wood comes into contact with water.A good example of this is when a curved toothpick is placed in water, it will draw water through the capillaries, elongate, and straighten.When the fibers on the board are exposed, they suck water into the wood like a straw, causing the fibers to swell and stick to the surf...
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 ...
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 ...
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...
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...
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...
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...
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:...
