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 enhanced molecular mobility and flexibility, making it an ideal crosslinking monomer for applications requiring a balance of flexibility, toughness, and durability. It is widely used in biomaterials, dental composites, coatings, sealants, and specialty adhesives.
