Key Features & Advantages

• Serves as an effective secondary acceleration component that activates and optimizes the performance of other accelerators in complex compound systems.

• Enhances rubber-to-metal adhesion properties, making it particularly valuable for rubber products requiring strong bonding with metal substrates.

• Provides excellent processing safety with moderate curing rates, allowing for controlled vulcanization across different manufacturing processes.

• Demonstrates particular effectiveness in EPDM compounds and natural rubber applications, ensuring reliable performance across multiple polymer systems.

• Produces vulcanizates with good aging characteristics and mechanical properties, maintaining long-term product integrity and performance reliability.

2. Usage

1). It is used as a medium-speed accelerator for natural rubber and synthetic rubber. It is often used as an active agent for thiazole, thiuram and sulfenamide accelerators. When it is used in combination with accelerators DM and TMTD, it can be used for continuous vulcanization. When the second accelerator of thiazole-based accelerators is used, the aging resistance of the vulcanized rubber will decline, and appropriate anti-aging agents must be added. In chloroprene rubber, there are the functions of plasticizers and solubilizers.

2). It is used for manufacturing rubber sheets, shoe soles, industrial products, tires, hard rubber and thick-walled products.

3). The dosage of this product as the first accelerator is 1-2 parts. When used as the second accelerator for thiazole accelerators, the general dosage is 0.1-0.5 parts. Its derivative, chromium tyrosine, is an efficient rust inhibitor. It is also used as a plastic crosslinking agent, temperature-indicating material, additive for ore flotation, coating additive, polishing material additive, metal analysis reagent and additive for building materials.
