May 4, the Chinese Consumers Association announced the market’s major brands of latex paint products, environmental protection and functional comparison of the results of the experiment, part of the latex paint claimed to have a basic function of purification of formaldehyde, but the role is limited.
This comparison test sample by the Chinese Consumers Association staff as an ordinary consumer in the market at random purchase, the product name trademarks involving Dulux, Nippon, Carpoly, morning sun, three trees, are Fang, Bauhinia, Fuya, Laiwei, Signeo, PIGROL, TIKKurila, California and other brands, a total of 20 samples. 20 samples are white paint. In the sample, there are 3 samples of the standard children’s paint, and there is a sample of the stain resistance performance, and there are 14 samples with anti-fungal properties, 11 samples of formaldehyde purification function.
Comparison of the test based on “interior wall stain resistant latex paint” “indoor air purification function coating material purification performance” “antibacterial coating” “elastic architectural coatings” “building anti-graffiti anti-paste coating” and other standards, the coating coating appearance, Contrast ratio, scrub resistance, stain resistance, formaldehyde purification performance, anti – mold performance, tensile strength, elongation at break, anti – graffiti and other items were tested.
The results show that the vast majority of the sample cover the strong performance of the sample stain resistance performance is different, there are 13 stain resistance better. One of the children’s paint showed stain resistance performance, the other 19 samples, although not express the performance, but there are 12 stain resistance performance is also better. From the test results, the purchase of children’s paint samples have a good stain resistance.
According to the standard requirements, latex paint scrub resistance performance to be washed after 2000 times the film is still not damaged in order to meet the requirements. 20 samples of 2 samples were washed after 2000 times the film was scratched, respectively, from the Jingdong Mall purchased the nominal three tree paint Co., Ltd. and from the Shilihe Min Le building materials market to buy the nominal Beijing Fuya paint Limited latex paint. Other samples performed well.
The test results also show that the comparative test samples have good anti-fungal properties. 20 samples of 19 samples in the test anti-fungal performance for the Ⅰ, 1 sample in the test anti-fungal performance for the Ⅱ level. In the 20 comparative test samples, 14 samples claimed to have anti-fungal function, the anti-mildew grade reached grade Ⅰ, the rest did not claim to have anti-fungal properties, but also good anti-fungal properties.
After testing, there are 13 samples of formaldehyde purification function, of which 11 claimed to have formaldehyde purification function, its publicity is basically true. Need to remind is to remove the indoor air formaldehyde, the role of net aldehyde latex paint is limited, the selection of environmentally friendly decoration materials is the most fundamental way.
