After the paint is stored for a period of time, the pattern particles will sink and there will be a layer of protective glue solution on it. This layer of glue solution generally accounts for about 1/4 of the total amount of paint. For paint and coating with good quality, the protective glue solution is colorless or yellowish and clear; The paint and coating with poor quality, the protective glue solution is turbid, and obviously presents the same color as the pattern color particles. The main problem is not the poor stability of the paint and coating, or the storage period has expired, so it is not suitable for reuse

◆ look at the floating debris

for high-quality paint and coating, there is usually no floating debris on the surface of the protective glue solution, and sometimes there are very few color particle floating debris, which is normal; However, if there is a large number of floating objects, or even a certain thickness, it is abnormal

◆ look at the particle size

take a transparent glass, fill it with half a glass of water, then take a little paint, put it into the water of the glass and stir it. For high-quality paint, the water in the cup is still clear, the particles are relatively independent in clear water, and the particle size is very uniform

◆ according to the sales price

paint coatings with good quality are produced by regular manufacturers according to the formula, and the price is moderate; Some of the poor quality paints and coatings are cut corners in production, and some are even produced by personal imitation. The cost is low, and the sales price is much cheaper than that of good quality paints and coatings
