QDO® Vulcanizing Agent Where To Buy

Product Information

LORD Quinone Dioxime (QDO®) agent is a non-sulfur vulcanizing agent for synthetic elastomers. It is used extensively for rapid curing of butyl stocks requiring heat resistance. Elastomers of this type are used to fabricate high voltage wire/cable products; molded electrical components; and heat-resistant seals and hose.

QDO agent is also used as part of the curative system for liquid butyl elastomers. These compounds are formulated as coatings, sealants and electrical encapsulants.

Shelf Life

Shelf life is two years from date of shipment when stored in a cool, dry environment at 10-32°C (50-90°F) in original, unopened container.
