| DSM’s Somos® ProtoGen 18120 is a liquid, ABS-like photopolymer that produces accurate parts ideal for general purpose applications. Somos® ProtoGen resins are the first stereolithography resins to demonstrate different material properties based on machine exposure control. Based on Somos® Oxetane™ chemistry, Somos® ProtoGen 18120 offers superior chemical resistance, a wide processing latitude and excellent tolerance to a broad range of temperature and humidity, both during and after the build. Applications This high-temperature resistant, ABS-like photopolymer is used in solid imaging processes, such as stereolithography, to built three-dimensional parts. Somos® ProtoGen 18120 provides considerable processing latitude and is ideal for the medical, electronic, aerospace and automotive markets that demand accurate RTV patterns, durable concept models, highly accurate and humidity & temperature resistant parts.&& |
