Bonding Antioxidant PW‑60 improves metal adhesion during vulcanizing of rubber in industrial processing
In industrial rubber manufacturing processes such as seals, gaskets, or tubing, reliable metal-to-rubber adhesion during the vulcanization of rubber is essential. Bonding Antioxidant PW‑60, developed by HEWITT CHEMICAL, is used during vulcanizing rubber to promote strong bonding between rubber and metal substrates. As a ketone-amine compound synthesized from acetone and RT base, it enhances resistance to thermal oxidation and flexural cracking, making it suitable for high-temperature, high-load environments. The compound’s structure contributes to long-term durability in precision parts exposed to thermal stress.
Enhancing structural integrity of vulcanized tires through bonding performance
In tire production, where steel cords or fabric layers are embedded into rubber structures, stable bonding is key to performance. The use of PW‑60 helps improve bonding at the vulcanizing stage by chemically promoting adhesion between rubber and reinforcement materials. Its antioxidant and anti-flex cracking capabilities ensure that vulcanized rubber components such as belts and sidewalls maintain integrity under repeated stress. This is particularly valuable in maintaining tire reliability over long service periods.
Durable vulcanized rubber components in automotive assembly
Automotive components like bushings, seals, and dampers made of vulcanized rubber must endure heat, oil, and mechanical loads. HEWITT CHEMICAL’s Bonding Antioxidant PW‑60 supports these requirements by improving adhesion between rubber and metals during the vulcanizing rubber phase. It also enhances the thermal oxidation resistance and fatigue crack resistance of the end products. This ensures that such components maintain performance in engine compartments or suspension systems over extended operational cycles.
