Scope

1 This International Standard specifies the methods to be used for the evaluation of sulfenamide accelerators. 2 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) 2.1 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. 2.2 CBS: N-cyclohexylbenzothiazole-2-sulfenamide 2.3 TBBS: N-tert-butylbenzothiazole-2-sulfenamide 2.4 DIBS: N,N'-diisopropylbenzothiazole-2-sulfenamide 2.5 DCBS: N,N'-dicyclohexylbenzothiazole-2-sulfenamide 2.6 MBS: N-oxydiethylenebenzothiazole-2-sulfenamide
