Rubber Chemical DOTG Accelerator (Di-ortho-tolylguanidine) is a guanidine-based accelerator commonly used in rubber compounding processes. It functions primarily as a secondary accelerator and activator, particularly in sulfur curing systems, where it enhances the performance of primary accelerators such as thiazoles and sulfenamides.
DOTG is typically used in natural rubber (NR) and synthetic rubber formulations including SBR and NBR. It contributes to improved cure efficiency and processing stability during vulcanization. Due to its delayed action characteristics, it provides better processing safety and is suitable for applications requiring controlled curing behavior.
The product is generally supplied in powder form and is incorporated during the mixing stage of rubber compounding. It is widely used in industrial rubber goods, molded components, and extruded products where consistent curing and process control are required.
