How to distinguish the quality of paint and coatings
As an important part of anti-corrosion and decoration, the quality of paint and coatings directly affects the service life of the base material. If the base material is damaged due to substandard coatings, it would be a loss. So, how to distinguish the quality of coatings? Here are some simple methods for you.
1. Look at the water; After being stored for a period of time, the pattern particles of paint coatings will sink and there will be a layer of protective glue solution on top. This layer of glue solution generally accounts for about one quarter of the total amount of paint and coating. All high-quality paint coatings and protective glue solutions are colorless or slightly yellow and relatively clear. Poor-quality paint and coatings, however, have a turbid protective glue solution that obviously shows the same color as the pattern color grains. The main problem is either poor stability of the paint and coatings or that their storage period has passed and they are no longer suitable for use.
2. Check for floating objects: For high-quality paint and coatings, there are usually no floating objects on the surface of the protective glue solution. Sometimes, there are only a few floating color particles, which is normal. However, if the number of floating objects is large or even they have a certain thickness, it is abnormal.
3. Observe the particle size; Take a transparent glass, fill it with half a cup of clear water, and then add a little paint or coating to the water in the glass and stir. For high-quality paint and coatings, the water in the cup remains clear to the bottom, the particles are relatively independent in the clear water, and the particle sizes are very uniform.
4. Check the selling price; High-quality paints and coatings are all produced by regular manufacturers according to the formula, and the prices are moderate. Poor-quality paint and coatings, some are produced by cutting corners during manufacturing, and some are even counterfeited by individuals. They have low costs and are sold at much lower prices than high-quality ones
The above are some simple methods to identify the quality of paint and coatings. Of course, when purchasing paint and coatings, it is best to choose well-known brands, such as Jianbang Coatings, etc. If the quantity is large, it is best to ask the manufacturer to provide the corresponding test report, so that the quality can be guaranteed.
