The decorative paints currently on the market actually contain two major categories of products, one is oily solvent wood coating used to paint furniture, flooring, referred to as paint; the other is water-based solvent wall paint, also called Latex paint. The proportion of decoration paint in the cost of housing renovation in a family unit is not high, but it is very important. Because it is the last process, the aesthetics and comfort of the house decoration depend on this process. The last process was not done well, not only did not look beautiful, but it was uncomfortable to live in. It may even have adverse consequences for the health of the family because of the improper selection of paint.
To the building materials market, four or five hundred paint and coating brands, which is the best? Which is the worst? Due to the special nature of the paint, it is generally difficult to distinguish clearly. Here, I briefly introduce a little regularity from two aspects.
In the first aspect, what is good paint?
First, in terms of performance, a good paint has a high solid content and a low VOC content of a volatile solvent. The solid paint has a large paint area, or the paint is thicker and fuller in the same area. It is more cost-effective to buy such paint. The solid content of different paints on the market now differs greatly. Paints with low solid content may be cheaper, but if you want to brush to the same thickness and fullness, you must buy more; or buy the same amount of paint, you can only brush it thinly, the thickness and fullness of the film are not enough. of
Second, good paints have high hardness, good wear resistance, and stronger adhesion to the substrate. Such paints have a longer life span.
Third, good paint has better transparency and can fully reflect the characteristics of the substrate.
Fourth, good paint has better yellowing resistance and lasts as new.
Fifth, good paint construction performance is better, and the painted paint film is more flat and beautiful.
Sixth, a good paint solvent evaporates faster, and after a few days of painting, it smells no smell. Here to remind everyone: Some paints smell a little fragrant when they are painted. In fact, it is not the best paint, because the toluene and xylene aromatic substances contained in this paint are still somewhat toxic. The real good paint is that it is a bit of a nose when it is painted after opening the can, but it does not taste after a day or two of painting.
Finally, and most importantly, the environmental performance of the paint, the good toxic and hazardous substances in the paint are very low. The toxic and harmful substances in paint include volatile solvents VOC, aromatic solvents such as benzene, toluene and xylene, heavy metals such as lead, mercury and cadmium, and free TDI. These substances are very harmful to the human body, especially the children's body. Therefore, the national mandatory standards have very strict requirements on the content of these substances in the paint. Guangdong Bardez Chemical Co., Ltd. introduced the “full-effect decoration paint†to the market, in which the content of benzene, toluene, xylene and heavy metals are controlled within a very low range that cannot be detected by the most advanced testing instruments. The free TDI content is controlled within 0.1%, which is far below the national mandatory standard of 0.7%. This is the closest paint product on the market.
