11122 XC Watershed
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. This makes the material ideal for many applications in the automotive, medical,and consumer electronics markets. Most importantly parts created with 11122 XC Watershed are nearly colorless and look more like true, clear engineered plastic.
