Silway 520 is a polydimethylsiloxane polymer manufactured to yield essentially linear polymers in a wide range of average kinematic viscosities.
Dimethyl silicone oil is colorless,transparent, odourless and non-toxic oil liquid. The viscosity increases with the added of N value of SI-O chain, from highly mobile liquid to thick semisolid

Machine Textile Paint
As Defoamer
Due to the feature of low surface tension, insoluble, and chemical stability, Dimethyl Silicone Oil is used as defoamer/antifoamer in petrochemical industry, medical industry, pharmaceutical industry, food processing, texture, printing and dyeing, paper industry., etc.
As Lubricant
As lubricant, Dimethyl silicone oil is suitable for rubber, plastic bearings, and gears. Also be proper for rolling friction between steel materials to steel or other metals under high temperature.
Remarkable: In general case, Dimethyl silicone oil is not suggested as lubricant between metals in room temperature.
As Mold Release Agent
Due to the non-stick ability on rubber, plastic and metal, etc.,Dimethyl Silicone Oil is often used as mold releasing agent during molding process of rubbers and plastic products.
As mold releasing agent, Dimethyl Silicone Oil not only demold easily, but leaves clean, smooth,and clear grain on the surface of products.
As coating of lnsulation, dust/mould proof
Applying a coat of Dimethyl Silicone Oil on the surface of glass or ceramics, then making heat treating by 250 - 300 ºC, a semi permanent waterproof, mould proof and insulation membrane.
