SINOMER® DDDA (1,12-Dodecanediol Diacrylate) is a difunctional acrylic monomer featuring a long C12 hydrophobic spacer chain between two reactive acrylate end groups. This unique structure provides low viscosity, enhanced molecular mobility, and excellent flexibility to cured films. The long hydrophobic backbone effectively reduces curing shrinkage while imparting outstanding weatherability and surface characteristics. With fast UV/EB curing response and non-yellowing properties, SINOMER® DDDA is an ideal crosslinking monomer for applications requiring flexibility, toughness, and durability.
