LORD Introduces Lead-Free, Eco-Friendly Rubber-to-Metal Adhesive Chemlok® 6125 to Support Green Manufacturing

LORD, a division of Parker Hannifin Corporation focused on high-performance material solutions, recently highlighted one of the core products in its eco-friendly rubber-to-metal bonding portfolio – the Chemlok® 6125 adhesive. This product is a lead-free formulated covercoat adhesive designed to be used in conjunction with primers such as Chemlok 205, specifically for achieving high-strength, durable bonds between various unvulcanized elastomers and metal or rigid substrates during the vulcanization process. Its promotion actively responds to the growing global manufacturing demand for environmentally friendly materials, significantly reducing the environmental impact of production processes while ensuring exceptional performance.

Chemlok 6125 is a mixture formed by polymers, organic compounds, and mineral fillers dissolved and dispersed in an organic solvent system. One of its most prominent features is its "lead-free" design. According to the product technical data sheet, its formulation does not intentionally incorporate lead components. Compared to traditional lead-containing adhesives, this significantly reduces the potential environmental emissions of heavy metals during production and throughout the product lifecycle. It assists downstream customers, particularly in industries with stringent material environmental requirements such as automotive and electrical appliances, to better comply with relevant regulations and standards.

In terms of application, Chemlok 6125 demonstrates excellent versatility. When combined with the Chemlok 205 primer to form a bonding system, it can effectively bond various common elastomers such as Natural Rubber (NR), Styrene-Butadiene Rubber (SBR), Nitrile Rubber (NBR), Isoprene Rubber (IR), and Butadiene Rubber (BR) to metals. This combined system relies on the primer to ensure the bonded assembly's excellent environmental aging resistance and adhesion strength, while the covercoat Chemlok 6125 provides the primary bonding strength and cohesion. After proper application and vulcanization, this system forms a continuous and uniform adhesive film, providing reliable long-term protection for components.

Based on the technical characteristics of Chemlok 6125, its typical application scenarios cover numerous industrial fields. In the automotive manufacturing industry, it is commonly used in the production of key components such as engine mounts, transmission brackets, various damping bushings, and damping blocks, which need to withstand continuous vibration, fluid exposure, and temperature changes. In general industrial sectors, it can be used for bonding in the manufacture of industrial rollers, seals, conveyor belt joints, and various tool handles or equipment pads that require rubber-metal composites. Its reliable bonding performance ensures the structural integrity and functional stability of these composite components under harsh operating conditions.

By providing high-performance and environmentally friendly bonding solutions like Chemlok 6125, LORD Corporation continuously assists customers in addressing technical challenges and achieving sustainable development goals. The lead-free characteristic and broad rubber compatibility of this product make it an ideal choice for manufacturers pursuing both product reliability and environmental responsibility.
