Deltech Monomers Divinylbenzene 63% (DVB63)

1 of 9 products in this brand
Deltech Divinylbenzene 63% (DVB63) is a reactive monomer primarily composed of divinylbenzene and ethylvinylbenzene isomers. It is commonly used in the synthesis of ion-exchange resins and in the production of unsaturated polyester resins and casting resins, where DVB63 serves as a cross-linking agent, providing rigidity. The appearance of this product is that of a yellowish-clear liquid.

Chemical Name: Divinylbenzene, Ethylstyrene

Chemical Family: Vinyls, Vinylics & Vinyl Derivatives

Storage & Handling

Storage & Handling
  • 63% 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 63% 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 900-1200 PPM range.
  • Due to flammability danger, exposure of 63% 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.
