How to distinguish colorful paint?

First, look at the water and colorful paint after a period of storage, pattern particles will sink, there will be a layer of protective glue solution. This layer of glue solution generally accounts for about 1/4 of the total amount of colorful paint. The quality of a good and colorful paint, the protective glue solution is colorless or yellowish, and clearer; and the poor quality of the colorful paint, the protective glue aqueous solution is in a turbid state, clearly showing the same color as the pattern color particles, the main problem is not The poor stability of colorful paints means that the storage period is over and should not be used again.

Second, look at floating objects. In the case of good quality and colorful coatings, there is usually no floating object on the surface of the protective colloidal water solution, and sometimes there are very few color particles floating, which is normal; but if the number of floating objects is large or even has a certain thickness, it is abnormal. .

Third, look at the particle size. Take a transparent glass, fill it with half a glass of clear water, and then take a little colorful paint and stir it in the glass of water. Wherever the paint is of good quality, the water in the cup is still clear, the particles are relatively independent in the clean water, and the size of the particles is uniform. Four to see the sales price. Good quality and colorful paints are produced by the regular manufacturers according to the formula, and the price is moderate; while the paints with poor quality are used for cutting corners in production, some are even counterfeit, and the cost is low. The selling price is cheaper than the quality paint. Much more.
