Material Notes:

DescriptionDSM Somos® WaterClear Ultra 10122 is a next generation optically clear resin with ABS like properties and good temperature resistance. It produces colorless, functional, accurate parts that simulate acrylic in appearance. Based on the Oxetane Advantage™, the parts also have improved water resistance over the original WaterClear 10120 resin. WaterClear Ultra is a fast, low viscosity, general-purpose resin.ApplicationIdeal for applications requiring optical clarity such as:Automotive lensesBottlesFluid flow analysisPackaging prototypesLight pipesInformation Provided by DSM Desotech Inc.
