Material Notes:

DescriptionWaterShed XC is a low viscosity liquid photopolymer that produces strong, tough, water-resistant, ABS-like parts. Most importantly parts created with WaterShed 11122 are nearly colorless, and look more like true, clear engineered plastic. In addition, WaterShed XC has been formulated with the DSM Somos Oxetane Advantage™ - an advanced chemistry platform that produces parts with outstanding water resistance and high dimensional stability.ApplicationWaterShed XC 11122 offers many properties that mimic traditional engineering plastics including ABS and PBT. This makes the material ideal for many applications in the automotive, medical and consumer electronics markets and include:LensesPackagingWater flow analysisRTV patternsDurable concept modelsWind tunnel testingQuickcast patternsInformation Provided by DSM Desotech Inc.
