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...
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...
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...
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...
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...
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...
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...
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...

Plastics are classified into two types: thermosetting and thermoplastic.Among them, thermosetting plastics have high cross-linking density, good solvent resistance and heat resistance, relatively high surface polarity, and wide range of coatings available.For example, unsaturated polyester is called polyester fiberglass. The texture is hard and polar, and there are many coatings that can be used. ...
Adhesion type and adhesion property of paint film on substrate The adhesion of the paint film to the substrate is divided into two types: mechanical adhesion and chemical attachment.Mechanical adhesion depends on the properties of the coated sheet (roughness, porosity) and the strength of the formed film; chemical adhesion refers to the mutual attraction of the paint film molecules and the plate m...
