Overview:
SINOMER® DDDMA (1,12-Dodecanediol Dimethacrylate) is a difunctional methacrylic monomer featuring a long C12 hydrophobic spacer chain between two reactive methacrylate end groups. This unique molecular structure provides exceptional flexibility, low viscosity, and enhanced molecular mobility. The long hydrophobic backbone effectively reduces curing shrinkage while imparting excellent weatherability and surface characteristics to the cured polymer matrix.
SINOMER® DDDMA exhibits fast curing response and non-yellowing properties, making it an ideal crosslinking monomer for applications requiring a balance of flexibility, toughness, and durability. It is widely adopted in biomaterials, dental composites, coatings, sealants, and specialty adhesives.
