Bis(2-(methacryloyloxy)ethyl) phosphate
What is Bis(2-(methacryloyloxy)ethyl) phosphate?
Bis(2-(methacryloyloxy)ethyl) phosphate (CAS 32435-46-4) is a bifunctional phosphate monomer combining a reactive methacrylate group with a pendant phosphate moiety. Also known as bis(methacryloyloxyethyl) hydrogen phosphate.
Where is Bis(2-(methacryloyloxy)ethyl) phosphate used?
- UV- and thermally-cured coatings: reactive flame-retardant monomer bound into the polymer network
- Adhesives and sealants: improved bonding to metal and mineral substrates
- Printing inks and packaging coatings: substrate wetting and anchorage on aluminum foil and treated films
- Polymer compounders use it as a co-monomer to introduce inherent flame retardancy into acrylic systems.
Good to know: The phosphate group coordinates with surface oxides to enhance adhesion without a separate primer layer. The phosphate functionality delivers flame retardancy and surface adhesion promotion within a polymerizable matrix, eliminating separate additive packages and preventing plasticizer-style migration losses.
Commercial specifications
- Purity confirmed by acid value and phosphorus content assays
- Packaging from small R&D quantities to bulk drums
