DMSO Liquid CAS 67-68-5 Applications
Agricultural Chemicals Industry
DMSO serves as a carrier for pesticides and herbicides, helping these active ingredients reach crops faster and work better.It also delivers antifungal effects by stopping fungal growth and spore development, offering reliable control against common fungal pathogens.
Cleaning Applications
DMSO easily strips oils, greases and organic dirt off metal, plastic, ceramic and other materials. It works as a practical cleaner for automotive, electronics and general manufacturing sectors.It can clear tough sticky leftovers like glue and adhesive residues from glass, plastic and metal surfaces.Additionally, it acts as a paint remover, especially for metal coatings. With strong dissolving power, it replaces harsh, highly toxic chemical strippers for safer use.
Coatings Industry
As a strong polar solvent, DMSO dissolves most organic and inorganic materials, ideal for thinning coatings and printing inks.It seeps into base materials such as metal, glass and plastic to strengthen coating adhesion through stable chemical bonding.Blending DMSO into coating formulas also promotes even spreading and regulates drying speed thanks to its slow evaporation rate.
Electronics Industry
Its powerful dissolving capacity makes DMSO great for cleaning and decontaminating electronic parts and circuit surfaces.With high thermal conductivity, it can act as a cooling fluid for high-power electronic equipment where standard cooling solutions fall short.
Pharmaceutical Industry
DMSO dissolves diverse raw materials, supporting drug compounding, ingredient dilution and natural active substance extraction.It features anti-inflammatory and pain-relieving effects, widely applied in topical care products to ease discomfort from osteoarthritis and similar conditions.
Polymer Processing
This polar organic solvent assists polymer production by dissolving multiple resin materials. It acts as a co-solvent and softener to optimize the processing of plastics, rubber and elastic materials.It helps prepare polymer solutions for coating, lamination and molding. After being coated on surfaces, the solution hardens under heat or pressure to form a stable polymer film.
Textile Industry
DMSO cleans oil, grease and impurities from textile fibers, while also acting as a softener to boost fiber flexibility and texture.
Pulp and Paper Industry
In pulp production, DMSO functions as a dispersant to enhance chemical wetting and penetration. It also cleans key equipment for daily papermaking operations.
How to store DMSO solvent safely?
Keep in a cool, dry, well-ventilated place
Store in tightly sealed containers to prevent moisture absorption
Avoid heat, flames, and strong oxidizing agents
Use compatible containers (glass or stainless steel preferred)
Keep away from direct sunlight
