Deltech Monomers Divinylbenzene 80% (DVB80)

1 of 9 products in this brand

Deltech Divinylbenzene 80% (DVB80) is an extremely reactive monomer. It appears as a clear to slightly hazy amber liquid and has an odor characteristic of aromatic hydrocarbons. Special care is needed with DVB80, as heat-initiated free radical polymerization can easily occur, making the monomer molecule unstable when heated. To prevent premature free radical polymerization, it is treated with tertiary Butyl Catechol (TBC) as an inhibitor. DVB80 is utilized in various fields, including coatings, adhesive tackifiers, functional polymers, molded composites, and insulating varnishes.

Packaging & Availability

Packaging Type

80% DVB monomer is available in 55-gallon drums (non-returnable, DOT Specification 17E), tank trucks and tank cars. Sample quantities are available upon request.

Storage & Handling

Storage & Handling
  • 80% DVB monomer is a highly reactive and flammable liquid which requires use of proper storage techniques and adequate ventilation, fire protection and static electricity protection during transfer and use.
  • Due to high reactivity, violent reaction may occur if uncontrolled polymerization is initiated. Product in drums should not be exposed to direct sunlight and should be stored in a cool area. Bulk storage tanks should be refrigerated to maintain temperatures below 80oF.
  • To prevent polymerization, the inhibitor tertiary-butyl catechol (TBC) is added to 80% DVB monomer. Normal inhibitor concentration is 900-1200 PPM. Over time, the inhibitor concentration may become depleted. Lower concentration will not adversely affect the DVB unless the level falls below 900 PPM. At this point inhibitor should be added to restore the concentration to the 900-1200 PPM range.
  • Due to flammability danger, exposure of 80% DVB monomer to air should be limited. Containers should be kept closed at all times. However, presence of oxygen is required to maintain activity of the inhibitor. Complete inerting of the product is not recommended. Water extracts the inhibitor and should not be allowed to contact DVB.
  • Prolonged or repeated contact with the skin or breathing of vapors should be avoided. See the Material Safety Data Sheet for complete safety and toxicological information.
