DBQDO® Vulcanizing Agent Where To Buy

Product Information

LORD Dibenzoyl Quinone Dioxime (DBQDO®) agent is a non-sulfur vulcanizing agent for natural and synthetic elastomers. It is used for 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, jackets and hose; inner tubes; and tire curing bags.

DBQDO agent is similar to Quinone Dioxime (QDO®) vulcanizing agent in the properties it imparts to butyl, but different in its processing characteristics. DBQDO agent has a slower reactivity time, and is usually preferred when processing convenience is of primary importance.

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.

Features and Benefits

Heat Resistant – improves heat and electrical resistance of butyl stocks.

Processing Convenience – slow reactivity of DBQDO agent allows longer processing times.

Versatile – activated with red lead, benzothiazyl disulfide (MBTS), or peroxides; available in elastomer compatible dispersions.
