What is VOC? Does the adhesive sealant contain VOC?

What is VOC? VOC stands for Volatile Organic Compounds, a type of organic compound that easily evaporates at room temperature. They have high vapor pressure and low water solubility, and can enter the air through evaporation, participate in chemical reactions, and form photochemical smog or air pollutants. Common VOC include formaldehyde, benzene, toluene, ethanol, ethyl acetate, etc.VOC come from a wide range of sources, including industrial production, building materials, daily chemicals such as coatings, cleaning agents, adhesives, and transportation. Adhesive sealant, as a common chemical material used in construction and industry, may contain VOC in its composition.The impact of VOC on health and the environmentThe impact on healthShort term exposure: can cause symptoms such as dizziness, headache, nausea, throat and eye irritation.Long term exposure: Certain VOCs (such as benzene) are considered carcinogenic and may cause chronic respiratory diseases and neurological damage.The impact is greater on sensitive populations such as children, pregnant women, and the elderly.Impact on the environmentVOC and nitrogen oxides undergo chemical reactions under sunlight, generating ozone and photochemical smog, becoming one of the important causes of air pollution.VOC emissions may also lead to indoor air pollution and global warming.Does the adhesive sealant contain VOCsWhether adhesive sealant contains VOCs mainly depends on its type and formula composition. Traditional sealantMany early formulations of sealants contained highly volatile organic solvents, such as toluene and ethyl acetate, which were the main sources of VOCs. During use and curing, these solvents will evaporate into the air, causing adverse effects on human health and the environment.Modern environmentally friendly sealantWith the increasing demand for environmental protection, more and more adhesive sealants are adopting low VOC or VOC free formulas, mainly divided into the following categories:Water based sealant: Using water as a solvent, it contains almost no VOCs and is widely used in indoor decoration and…
