DSM的Somos ProtoCast 19122是投资铸造行业的一个突破。它是一种无锑的液态光聚合物,专门为生产熔模铸造型而配制。索莫斯ProtoCast 19122是铸造应用的理想选择,完全不含锑,消除了特殊合金污染的风险。锑传统上存在于激活立体光刻化学的光引发剂中。在这种独特的光聚合物化学中不存在其他金属。锑的缺乏也使得立体光刻图形的烧蚀更加彻底,从而使残余灰份明显低于传统立体光刻图形的烧蚀所产生的灰份。研究表明,SOMOS ProtoCast 19122在1500°F下燃烧两小时后,其残余灰量小于0.015%。 DSM's Somos® ProtoCast 19122 is a breakthrough for the investment casting industry. It is an antimony-free liquid photopolymer specifically formulated for producing investment casting patterns. Applications Ideal for use in foundry applications, Somos® ProtoCast 19122 is totally antimony-free, which eliminates the risk of contamination in specialty alloys. Antimony is traditionally present in the photoinitiators that activate the stereolithography chemistry. No other metals are present in this unique photopolymer chemistry. The absence of antimony also allows stereolithography patterns to burn out more completely, resulting in significantly lower residual ash than is produced by burning out conventional stereolithography patterns. Studies have shown that the residual ash of Somos® ProtoCast 19122 is less than 0.015% after burnout at 1500°F for two hours. |
