Chemical name: 1, 3-Diphenylguanidine
H. S No.: 3812100000
Molecular formula: C13H13N3
Molecular weight: 211.27
Structure:
Properties: No odor or poison. Specific gravity: 1.13--1.23. Soluble in chloroform, toluene benzene and ethanol; Insoluble in gasoline and water. Not hygroscopic.
Application: Used as a secondary accelerator with thiazoles and sulphenamides in NR and SBR compounds. Exhibits better storage stability compared to thiuram and dithiocarbamates but is not so active. Willing DPG can be used in latex as secondary gelling agent (foam stabilizer) in the silico-flouride foam process.
Storage: Keep container tightly closed in a cool, well-ventilated place. The recommended maximum storage life is 2 years when stored under normal conditions.
