Does paint contain formaldehyde? Does paint contain formaldehyde?

When we decorate our houses, we often use paint to make the colors of the houses more beautiful. However, after using paint, a very pungent smell will be produced in the room. The components of paint are film-forming substances, solvents, pigments, desiccants, additives, etc. Long-term contact with paint can easily lead to anemia and other diseases. So does paint contain formaldehyde? Does paint contain formaldehyde?

First, does paint contain formaldehyde? Environmentally friendly paint contains formaldehyde to a greater or lesser extent. It is impossible to have completely environmentally friendly paint because it contains substances such as benzene and formaldehyde. The definition of environmentally friendly paint is that the content of formaldehyde and benzene is lower than that of ordinary paint, and the harm to the human body is relatively small, so it is called environmentally friendly paint. However, due to the cumulative effect of indoor space, if too much environmentally friendly paint is used, there may be pollution, and formaldehyde may also exceed the standard!

Second, environmental protection qualification in environmental protection paint means that the content of toxic and harmful substances does not exceed the standard, but it does not mean that there are no toxic and harmful substances at all. Simply put, environmental protection paint does not mean non-toxic and harmless. If the same material is used in large quantities in a room, it may still cause the indoor air quality to exceed the standard. How long does it take to live in a house that has been painted with environmentally friendly paint? It is recommended to open the windows frequently for ventilation for one or two months after the new house is renovated, and then conduct air testing. The doors and windows should be closed for about an hour before the test.

Does paint contain formaldehyde? Does paint contain formaldehyde? Environmental protection indicators: VOC content. The country now implements a mandatory standard, namely VOC≤120g/L. There are three types of VOC effects on the human body: odor and sensory effects; pathological conditions caused by mucous membrane irritation and other systemic toxicity; certain volatile organic compounds have been proven to be carcinogens or suspected carcinogens. Formaldehyde content. The country now implements a mandatory standard value of ≤100mg/kg. Formaldehyde itself is highly toxic and has a strong coagulation effect on proteins. It can combine with the amino and hydroxyl groups of nucleic acids to denature them. It can hinder the action of gastric and pancreatic enzymes, thus affecting metabolic functions. Its vapor is carcinogenic to rodents. Heavy metal content. Heavy metals mainly refer to soluble substances such as lead, cadmium, chromium, and mercury. Some heavy metals are essential trace elements for the human body within a certain concentration, but when the amount entering the human body exceeds the limit that the human body can tolerate, it can cause serious physiological damage and trigger a variety of diseases. Lead poisoning is more serious for children, who are particularly susceptible to lead. US federal regulations CFR1303 stipulates that paints with a lead content greater than 60 mg/Kg are lead-containing paints and are prohibited from being used in public places or indoor decorations.
