What is Tetramethylene glycol diacrylate?
Tetramethylene glycol diacrylate (CAS 1070-70-8), abbreviated BDDA, is a bifunctional acrylate monomer derived from 1,4-butanediol.
Where is Tetramethylene glycol diacrylate used?
- UV-curable coatings and printing inks: viscosity control and crosslink density
- Adhesives and sealants: flexibility and cohesive strength in radiation-cured systems
- Plastics and polymer manufacturing: crosslinking agent that modifies gel content
- Personal care: crosslinker in gel-forming polymer networks
- It functions as a reactive crosslinker and diluent in UV- and peroxide-curable polymer systems.
Good to know: Supplied with inhibitor to prevent premature polymerization during storage and transport. Purity commonly specified at 98% or higher.
Commercial specifications
- Purity: 98% or higher
- Packaging: drums to IBC containers
