Propoxylated glycerol triacrylate

Propoxylated glycerol triacrylate (CAS 52408-84-1), also marketed as Ebecryl 53, is a trifunctional acrylate monomer used as a reactive diluent and crosslinker in UV- and EB-curable systems.

The propoxylation reduces skin sensitization potential compared to standard glycerol triacrylate, which influences formulator and procurement decisions in radiation-cure markets.

In UV-curable coatings, it lowers viscosity while contributing to crosslink density, allowing formulators to reduce photoinitiator loading without sacrificing cure speed or hardness.

Printing ink manufacturers use it in energy-curable flexographic and lithographic formulations where fast cure and low migration are required for high-performance applications.

Adhesive and sealant producers incorporate it into structural and pressure-sensitive systems to control flexibility and cohesive strength after the curing process is complete.

In plastics and polymer applications, it functions as a reactive crosslinking monomer in acrylate resin systems for optical films and protective coatings for various substrates.

Propoxylated glycerol triacrylate is supplied as a low-viscosity liquid. It is available in technical and industrial grades, with inhibitor levels specified to suit storage stability.

Processing requirements are met through rigorous quality control. Packaging typically ranges from drums to IBC totes for bulk industrial supply to global manufacturing facilities.
