| WaterClear™ 10120 Epoxy Photopolymer |
Description
DSM Somos® 10120 is a high-speed liquid photo-polymer that produces strong, rigid and durable parts with optical clarity using stereolithography machines. This material is especially useful in applications requiring optical clarity such as fluid flow analysis, stress analysis, and light pipes. Other applications include those that provide strong and durable product without the brittleness normally associated with a rigid stereolithography resin.
Application
Somos® 10120 Photopolymer is used in the solid imaging process to build three-dimensional parts. It is for use with a layer thickness of approximately 0.064 mm to 0.15 mm (0.0025 inch to 0.006 inch). After part formation via UV laser exposure, rinsing with a solvent such as tripropylene glycol monomethylether (TPM) or propylene carbonate, or 2-propanol (isopropyl alcohol, IPA) removes the excess resin. Somos® 10120 requires a minimal post-cure by UV fluorescent light. Prolonged exposure to UV light will create a yellow tinge to the parts.
