11122 XC Watershed SPEC SHEET
11122 XC Watershed is a low viscosity liquid photopolymer that produces strong, tough, water-resistant parts. It offers many properties that mimic traditional engineering plastics including ABS and PBT. Parts created with 11122 XC Watershed are nearly colorless and look more like true, clear engineered plastic.
