For decades, Chemlok® adhesives have helped engineers create durable rubber-to-metal bonds that improve performance, reduce vibration, and enhance reliability across countless applications. Discover the legacy of inventor Don Alstadt, explore the industries impacted by Chemlok technology, and access Parker Lord’s Chemlok® Adhesives Selector Guide to help identify bonding solutions for your next project.
Join us April 28 – 29, 2026, in Barberton, Ohio, for Organic Elastomers 360°, a multifaceted training event where you’ll learn how to examine the performance of organic elastomers from every angle. This hands-on event is hosted by RDAbbott in collaboration with Akron Rubber Development Laboratory (ARDL) and features expert contributions from companies across the rubber industry.
Donald Alstadt, inventor of the Chemlok® Rubber-to-Metal Adhesive System, has been inducted into the National Inventors Hall of Fame as part of its 2026 class. Alstadt, a chemist at LORD Corporation (now Parker Lord), patented this solvent-borne adhesive technology in 1956. His former schoolmate, RDAbbott’s Carl Hoglund, helped commercialize Chemlok.
Hallstar has published a technical paper about the function and selection of ester plasticizers, substances that are incorporated into a plastic or elastomer to increase its flexibility, workability or distensibility.
