Applications for 1,4 Butanediol dimethacrylate

BDDMA is commonly used in:

  • UV-curable coatings and inks

  • Thermosetting resins and composites

  • Adhesives and sealants

  • Elastomers and plastic modification

  • Photopolymer resins for 3D printing

Its difunctional methacrylate groups allow for efficient crosslinking, contributing to enhanced durability, chemical resistance, and dimensional stability in end products. BDDMA is often blended with other (meth)acrylates to optimize performance and cure profiles.
