At present, people's awareness of the environmental protection performance of home decoration is gradually improved, and the choice is also very clear for the green environmental protection type. Therefore, the market of low-quality green environmental protection coating is also more and more flooding, how can we identify the real green coating?
The real green paint must bear the "ten rings" mark issued by China environmental mark product certification committee. Don't just look at the word "national standard" on the general paint, because it is only the "access standard" for interior wall paint to enter the market.
Look at the paint surface. The protective glue solution layer of high-quality multi-color coating is colorless or yellowish and clear.
Smell whether there is pungent smell in the paint. Toxic paint may not have peculiar smell, but the paint with peculiar smell must be toxic.
If the coating has serious delamination, the quality is poor. Stir gently with the stick. After lifting, the paint will stay on the stick for a long time and cover evenly, which means the quality is better. Twist lightly with the hand, the more delicate, the better.
Check the quality inspection report of the product carefully, especially the VOC of the coating. At present, the national VOC content standard of coatings should be no more than 200 mg / L, and the better coating should be less than 100 mg / L, while the environmental protection coating is close to zero.
Ask about solvents. Good brands will limit the use of toxic solvents. Generally speaking, after the paint is dried, its solvent can basically volatilize, but there is a process, especially for the room temperature curing paint.
