C15H17N3

SOXINOL® DT		 Moderate Yes（little） Melting point :
≥170°C
White powder		 Soluble in chloroform. Slightly soluble in alcohol, toluene.
Insoluble in water, gasoline.
  1. Valcanization accelerators for NR, IR, BR, SBR, NBR and CR.
  2. Similar performance as SOXINOL® D except higher critical temperature and less staining because of less scorch.
  3. Shows high tensile strength.
  4. Show plasty to CR
