NURCHEM DOTG-75

Diorthotolyl Guanidine
C15H17N3
Molecular weight : 239
CAS : 97-39-2
EINECS : 202-577-6

PROPERTIES:
As a primary accelerator, it is very slow and therefore rarely used alone.NURCHEM DOTG-75 is an excellent secondary accelerator or booster for thiazoles and sulphenamides. It is often used with TMTM in CR. It gives faster cure rates and better mechanical properties in general purpose elastomers. It provides vulcanisates with high modulus but poor heat-ageing resistance.
APPLICATIONS:
It is an activator for accelerator HDC in ACM
compounds.
It is non-staining and suitable for NR and SBR.

Compared to a traditional EVM/EP(D)M binder, NURCHEM DOTG-75 allows :
l. Dust free products with a high level of filtration up to 38 μ.
2. Tack free products at room temperature.
3. Lower Mooney viscosity, improving quality of dispersion.
4. Scrap rate reduction thanks to filtration.
5. Wider compatibility with other elastomers.
