What is 1,3-butyleneglycol dimethacrylate?
1,3-Butyleneglycol dimethacrylate (CAS 1189-08-8), also referenced in procurement as BGDMA, is a bifunctional methacrylate monomer used as a crosslinker and reactive diluent in polymer systems.
Where is 1,3-butyleneglycol dimethacrylate used?
- Coatings: crosslinking comonomer in UV- and peroxide-cured systems
- Adhesives and sealants: cohesive strength and resistance to solvents and elevated temperatures
- Printing inks: viscosity reduction and network density in energy-curable systems
- Polymer and resin manufacturing: building block for acrylic sheet and dental composites
- It introduces covalent network formation during curing, improving hardness, chemical resistance and dimensional stability.
Good to know: An inhibitor is typically added to prevent premature polymerization during storage and transport.
Commercial specifications
- Purity commonly 97% or higher
- Drums and IBC containers for bulk; smaller packaging for laboratory and formulation development
