ProtoTherm 12120

About
DSM’s Somos® ProtoTherm 12120 is a liquid photopolymer that produces strong, high-temperature tolerant, water-resistant parts. Parts created with Somos® ProtoTherm 12120 have a cherry-red appearance which turns to an orange-red color after thermal treatment. Applications Somos® ProtoTherm 12120 differentiates itself from other high temperature stereolithography materials by increasing in tensile strength and maintaining decent elongation at break after thermal treatment. This makes the material ideal for many applications in the automotive and aerospace markets where strong parts that can resist high temperatures are needed.&&
