ISO 11235:1999 PDF

This International Standard specifies the methods to be used for the evaluation of sulfenamide accelerators.

The analytical methods are applicable for most commercial sulfenamide accelerators:

• Sulfenamides of primary amines (type I)
• Sulfenamides of unhindered secondary amines (type II)
• Sulfenamides of hindered secondary amines (type III)

MBTS: Benzothiazyl disulfide

CBS: N-cyclohexylbenzothiazole-2-sulfenamide

TBBS: N-tert-butylbenzothiazole-2-sulfenamide

DIBS: N,N′-diisopropylbenzothiazole-2-sulfenamide

DCBS: N,N′-dicyclohexylbenzothiazole-2-sulfenamide

MBS: N-oxydiethylenebenzothiazole-2-sulfenamide
