Elrick Vice-President of Tect, Inc. "THCT, Inc. was first in the effective stabilization of 1, 1, 1-trichIoroethane: first offering VYTHENE in early 1954."

VYTHENE may be used for an enormous variety of cleaning and process applications, due to its low toxicity, stability, solvent power, and fast evaporation rate.
