4-HYDROXYBUTYL ACRYLATE

4HBA, with a primary hydroxyl group at the end of a longer alkyl chain, gives excellent scratch resistance due to its high crosslinking ratio and unique flexibility

CAS No :2478-10-6
TSCA :2478-10-6
EINECS :219-606-3
ENCS :2-958

Features

  • 4HBA is the Acrylic ester which has a hydroxyl functional group and a double bond group in the molecule.
  • Various vinyl monomers can be copolymerized with 4HBA.
  • Polymers co-polymerized with 4HBA achieve a higher crosslinking ratio with curing agents .

Applications

  • Paint and coating materials (excellent scratch resistance, mechanical properties, and acid rain resistance )
  • Waterborne coatings.
  • Powder coatings.
  • UV/EB curable composition
  • Adhesives
  • Pressure sensitive adhesives
