A problem that has been encountered with many dyes is that they tend to degrade in sunlight. The SDTF studied fluorescent dyes in various laboratories and found that Eosine OJ and Tinopal CBS-X were relatively stable. However, when the same dyes were used in the field, it was discovered that they were not stable under warm and humid conditions owing to aqueous photolysis. The SDTF therefore decided to use dilute active ingredient and metal tracers that were more stable.

High heat output. Due to its high temperature, a steam tracing system provides a large amount of heat to the pipe. There is a very high heat transfer rate between the metallic tracer and a metallic pipe.
