Common problems with water-based paint: oil slick surface of paint Problem: The finished product has floating black spots or impurities on the surface. A lot of coating produce technical personnel to had encountered similar problem, there is in coating production process "small bubble" or small black dot cannot eliminate. Carefully examine these "little bubbles" ~ they are actually small black oil...

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...

Factors Affecting Shrinkage of Waterborne Coating Films In practice, the main causes of shrinkage are as follows: 1. The substrate is contaminated by oil or impurities 2. Apply a paint to the old paint or finish without sanding 3. The interval between constructions of the two paints is too long 4. Too much defoamer in the paint The following focuses on two factors: defoamer and impurity contaminat...

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...

In the solid paint, white paint is taken as an example. The amount of titanium dioxide should be sufficient to ensure that the paint film has sufficient capping power. The amount of titanium dioxide should not be lower than 13%, but it is not necessary to be higher than 22%. The situation is the same as solvent-based white paint. Fillers may be added or not added. However, a small amount of filler...

The addition of wetting dispersant has obvious effect on the foam of some water-based ink.For example, polyacrylic acid wetting dispersants foam more than other types of wetting dispersants.Generally speaking, wetting dispersant foam with low dispersion capacity is also less. If diisobutyl sulfonate is based on disate, there is little foam at its content of 0.1-0.25%. The use of thickeners will ma...

Most coatings are composed of a base material (one or more resin mixtures), pigments (including physical pigments and functional pigments), solvents and some small amounts of additives and other coating raw materials. In the production of coatings, after the selection of various coating raw materials necessary for coating components, the next is how to make reasonable use of the technical and econ...

First, water-based lotion Aqueous emulsion is a colloidal dispersion system with water as the continuous phase and oil or other non-aqueous substances as the dispersing phase. It is a stable dispersion system formed by tiny oil droplets coated with surfactants. Water-based emulsion has many significant advantages, such as its low viscosity, easy to brush, easy to clean, non-toxic and harmless. The...

The grinding fineness of paint is one of the important qualities of color paint, which has a great impact on film forming quality, film gloss, durability, storage stability of paint, etc., and is one of the routine testing items of paint production. The fineness of the paint refers to the size of the particle size or the uniformity of the dispersion of the pigment or the bulk pigment, and the unqu...
