Lord Corporation has announced its introduction of a new film adhesive that will be used to bond un-vulcanized rubber to metal. The company says that as many as four layers of solvent-based primers, adhesives, and tack cements were needed to line metal pipes and tanks with rubber, but that its product achieves the task with a single film of adhesive.
The Chemlok Film Adhesive is VOC-free, which, says Lord Corporation, will improve workplace safety conditions while saving time, since instead of waiting for 30 to 40 minutes for the curing of several successive layers, a single film layer can now be applied. The company also says that its adhesive can be pre-laminated onto rubber, allowing workers to apply the adhesive outside of confined tank spaces.
Additional properties that Lord Corporation highlights include its product’s chemical resistance and high tack strength which nevertheless allows for repositioning of liners to ensure a good fit. The company says that it will continue to explore opportunities for the development of solvent-free adhesive technologies.
