Bis(2-ethylhexyl) maleate

Bis(2-ethylhexyl) maleate (CAS 142-16-5), also known as dioctyl maleate or DOM, is a reactive ester monomer.

Where is Bis(2-ethylhexyl) maleate used?

• Acrylic and vinyl copolymers: reduces glass transition temperature
• Coatings, pressure-sensitive adhesives and sealants: improves film flexibility
• Printing inks: reactive diluent that lowers viscosity and binds into the resin
• PVC and specialty elastomers: reactive plasticizer resisting extraction
• Adhesives for demanding substrates: tunes tack and peel strength
• It serves as a copolymerizable building block and internal plasticizer.

Good to know: Its dual functionality modifies flexibility and processability within the polymer backbone rather than by post-blending; chemical bonding avoids the migration issues of conventional solvents.

Commercial specifications

• Purity typically 98% or above
• Clear liquid in drums, IBCs and bulk tankers
