Annotation

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

NOTE Although MBTS is not a sulfenamide, it is the primary decomposition product of these accelerators and quantitatively determined by the method specified in 4.2.

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
