Paint coating VOC value is more important

For formaldehyde, we believe that consumers are already familiar with it and its harm is well known. For a time, businesses are all flaunting their products zero formaldehyde. Is zero formaldehyde safe? In fact, you have overlooked an important indicator - VOC, that is, volatile organic compounds.

Formaldehyde is not the only indicator of product safety

In recent years, with people's attention to environmental protection and health, the home market has become increasingly popular with environmentally-friendly products. When many merchants promote their own products, they will create a “zero formaldehyde”, green pollution-free propaganda slogan, and even many products, because the so-called “zero formaldehyde” also raises its value. In particular, paint products, many companies just take formaldehyde to say things. However, some experts have stated that the decoration material that is completely free of formaldehyde so far does not exist. In general, furniture and paints will contain more or less formaldehyde, but it is just a question of how much the formaldehyde component is and whether it meets the national standards.

At the same time, regarding the problem of formaldehyde in paint products, experts believe that paints containing formaldehyde are mostly used for waterproof and antiseptic purposes. Normally, the content of regular products is not high, and the release is fast, and it is not easy to cause too much formaldehyde damage to the interior. According to Zhang Honggen, the chairman of the home-installer, formaldehyde is generally easier to detect and, therefore, is likely to attract attention. Another important indicator that has long been overlooked is VOC.

Values ​​can not be ignored

VOC is the English abbreviation of volatile organic compounds. Commonly referred to as the harmful chemical substances (excluding heavy metals) in latex paints refer to VOCs. When VOC reaches a certain concentration in the room air, people will begin to feel headaches, nausea, and weakness in the limbs; if they continue to stay for a long time, they will injure the liver, kidneys, brain and nervous system, and may even cause convulsions, coma, and memory loss. Serious consequences.

VOC harm is so serious, but where does it come from? Experts pointed out that building materials such as walls, ceilings and floors, as well as latex paints, wallpapers, thermal insulation materials, adhesives and other decorative materials are the main sources of VOCs.

It should be particularly pointed out that the most commonly used VOCs of latex paint for decoration are mainly VOCs of raw materials, including formaldehyde, ammonia, and ethylene glycol. Therefore, it is very important to control the VOC content of raw materials. Especially for the interior wall paints, VOC (harmful substances) content is to be compared, and the lower the VOC, the more environmentally friendly.

Zero formaldehyde, more to zero

At present, due to the high degree of attention to formaldehyde, many home brands take formaldehyde as an article, but at the same time, they often overlook the content of VOCs. Therefore, when selecting household products, especially paint products, it is necessary to particularly check the VOC value of the test report. At a brand new product promotion meeting, the reporter saw that in the test reports on a number of brand products, the formaldehyde content was negligible or in line with national standards, but the VOC value of some products was in a relatively high range. This brings security risks to the health of consumers. Zhang Honggen said that formaldehyde is also present in many natural materials and is easier to prevent because of its ease of perception. And VOCs are more from the added ingredients, which requires consumers to pay more attention to the big brands and do not add harmful substances such as flavors and odors. For example, the European Union Tushi paint on the CCTV brand is your first choice for home improvement.

With regard to the VOC content of interior wall latex paints, the national provisions for “injury content of interior decoration and decoration materials” should not exceed 200 g/l; the “Environmental Mark Certification Standard” requires ≤100 g/l; the standards of developed countries are more stringent and EU standards The VOC content of mid-matt latex paint shall be ≤75 g/l.
