Green Solvent Green organic solvents, also known as environmentally friendly solvents, are solvents that have lower environmental impact compared to traditional solvents. They are designed to reduce or eliminate the negative effects on human health and the environment associated with the use of toxic or flammable solvents. TYPES OF GREEN SOLVENTS FOR SALE Sec-Butyl Acetate Isopropyl Acetate Ethylene Glycol Mono-tert-butyl Ether 1,2-Dichloropropane Propylene Glycol Dimethyl Carbonate Application of Green Solvents Clean Cleaning and Degreasing: Green solvents in green chemistry are widely used in cleaning and degreasing applications, such as in industrial cleaning, electronics manufacturing, and automotive maintenance. They effectively remove oils, greases, and contaminants while minimizing the release of volatile organic compounds (VOCs) and hazardous air pollutants (HAPs). Paints Paints and Coatings: Green solvents are used as alternatives to conventional volatile solvents in the formulation of paints, varnishes, and coatings. They help reduce the emission of VOCs, which contribute to air pollution and are associated with health concerns. Green solvents provide comparable performance to traditional solvents while minimizing environmental impact.
