One、Are waterproof coatings toxic?
Low-quality waterproofing materials can be toxic.
Poor-quality waterproofing materials are typically made from coal tar or raw materials containing some coal tar. The volatile tar fumes have a pungent odor, and due to the large molecular weight of the tar fumes, they can easily accumulate in poorly ventilated indoor environments. Rapid inhalation of these fumes can lead to quick poisoning and death.
Additionally, another drawback of these waterproof coatings is the use of organic solvents as diluents, which typically include toxic substances such as toluene and xylene. Due to the dense surface of the waterproof coating film, the solvents require a long time to evaporate completely. After the construction project is completed, the polluting substances will be released over a certain period, and prolonged, low-level exposure to tar fumes and benzene can cause respiratory diseases, dizziness, nausea, and even cancer.
Two. Do waterproof coatings contain formaldehyde?
Waterproof coatings contain formaldehyde.
Formaldehyde, with the chemical formula HCHO, also known as formic aldehyde. It is a colorless gas with a characteristic, irritating odor that can irritate the eyes, nose, and other parts of the body. As a chemical product, waterproof coatings typically contain formaldehyde components. However, regular products have formaldehyde content that is controlled within safe limits, so there is no need to be overly concerned.
III. How to correctly choose non-toxic waterproofing materials
1、Choose reputable brands
Currently, the market for waterproof coatings is also full of mixed offerings. Therefore, consumers should carefully evaluate their options and choose reputable brands to ensure the quality of waterproof coatings.
2、Purchase from authorized channels
With the development of the times, shopping channels have become increasingly diverse, and some unscrupulous merchants may take advantage of this to make a profit. Therefore, when selecting waterproof coatings, it is essential to choose legitimate channels.
3. Avoid cutting corners.
"You get what you pay for." This principle applies to waterproof coatings as well. When choosing waterproof coatings, avoid compromising on quality for the sake of low prices.
