What is Propoxylated glycerol triacrylate?
Propoxylated glycerol triacrylate (CAS 52408-84-1) is a trifunctional acrylate monomer used as a reactive diluent and crosslinker in UV- and EB-curable systems. Also marketed as Ebecryl 53.
Where is Propoxylated glycerol triacrylate used?
- UV-curable coatings: lowers viscosity while contributing to crosslink density, allowing formulators to reduce photoinitiator loading without sacrificing cure speed or hardness
- Energy-curable flexographic and lithographic printing inks: fast cure and low migration
- Adhesives and sealants: controls flexibility and cohesive strength after curing
- Plastics and polymers: reactive crosslinking monomer in acrylate resin systems for optical films and protective coatings
- Propoxylation reduces skin sensitization potential compared to standard glycerol triacrylate.
Good to know: Propoxylation reduces skin sensitization potential compared to standard glycerol triacrylate, which influences formulator and procurement decisions in radiation-cure markets.
Commercial specifications
- Inhibitor levels specified to suit storage stability
- Packaging typically ranges from drums to IBC totes for bulk industrial supply
