Water-in-water multi-color paint spray guns to use most of the spray, for the operation, but also because of the improper use of the gun caused by uneven distribution of the coating,the following together to see how to solve it. The smaller the gun distance, the greater the pressure of the spray, the greater the impact of the product by the pressure of the water, water-in-watercolorful paint coati...
Phenomenon : Part of the water-based paint film from the primer uplift, which contains gas or liquid, showed uneven distribution. Cause 1.When the water-based paint is applied, the dry water-based paint film is exposed to rain. 2.Apply a water-based paint primer to the wet substrate. 3.Water - based paint film is affected by acid - base and heat. Amelioration 1.Considering the gas phase conditions...
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...
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 ...
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....

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...
Water - based coating formulation design system Waterborne coatings, including waterborne wood lacquers, are water-based dispersions and diluents. Unlike conventional solvent-based coatings, the formulation system is a more complex system.When formulating, not only the type of polymer, the properties of the emulsion and the dispersion are concerned. It is also necessary to rationally select variou...
Water-based coating formulation design system - preservative Water-based wood coatings are water-based systems that are easier to bring into bacteria during production and are more susceptible to microbial degradation during storage. Therefore, the type and amount of preservatives should be properly added during formulation to prevent system and coating corruption.From the perspective of environme...
The adhesion of the paint film is caused by the mutual attraction between the paint and the polar groups on the surface of the coated substrate, and the mutual attraction between the polar groups is based on the premise that the paint is well wetted on the surface of the coated substrate.Since the wet condition of the coating on the surface of the coated substrate depends on the surface tension of...
Waterborne paint testing and standards:hardness Hardness is one of the most important physical properties of a coating. Coating hardness reflects the coating's ability to resist constant dents, scratches, scribes, and penetrations caused by a hard object. Testing the hardness of materials with different methods will give different results because the testing methods are for different amounts of ma...
