LORD Introduces Chemlok® 205GB, a New Rubber-to-Metal Bonding Primer Compliant with China VOC Standards

Lord, recently announced the addition of a significant new product to its high-performance adhesive lineup – Chemlok® 205GB. Designed specifically to meet stringent environmental regulations in the Chinese market, this primer/surface treatment offers a reliable and convenient solution for achieving strong, durable bonds between nitrile rubber (NBR) and metal substrates. It particularly assists manufacturers in sectors such as automotive and industrial equipment in achieving both environmental and performance goals.

Chemlok 205GB is a versatile product, with its core characteristic being application flexibility. It can be used either as a substrate primer in conjunction with various covercoats such as the Chemlok 6000 and 230 series to build a stronger bonding system, or as a one-coat treatment to directly facilitate the bonding of unvulcanized nitrile rubber to rigid substrates during vulcanization. This "dual-use" design provides more options for production processes, adapting to different performance requirements and manufacturing workflows.

In terms of application, Chemlok 205GB primarily serves the manufacturing of components that require a strong bond between nitrile rubber and metal. Nitrile rubber is renowned for its excellent oil resistance, making this adhesive ideal for products such as automotive engine mounts, damping bushings, oil seals, as well as industrial seals, rollers, and oil-resistant pipe connectors. When used as a primer in conjunction with the Chemlok covercoat system, it provides these critical components with exceptional tear strength, high cohesive strength, and excellent environmental resistance, thereby extending component service life and enhancing overall equipment reliability.

With the introduction of Chemlok 205GB, Lord once again demonstrates its commitment to solving specific customer challenges through material science innovation. This product not only helps customers meet specific environmental compliance requirements but also provides new leverage for improving production efficiency and product quality through its application convenience and reliable performance.
