Water-Resistant Resin for SLA

An easy-to-use, low viscosity, water-resistant SLA material for numerous applications.

Overview

Somos WaterShed XC 11122 is a low viscosity liquid photopolymer, which produces strong, tough and water resistant ABS-like parts. As a colour-less material, WaterShed XC has many properties that mimic traditional engineering plastics such as ABS and PBT. It is not only water resistant, it also has a high dimensional stability.
