Overview:
SINOMER® DDDMA (1,12-Dodecanediol Dimethacrylate) is a difunctional methacrylic 单体 featuring a long C12 hydrophobic spacer chain between two reactive methacrylate end groups. This unique molecular structure provides exceptional 柔韧性, 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 快速固化 response and non-yellowing properties, making it an ideal crosslinking 单体 for applications requiring a balance of 柔韧性, toughness, and durability. It is widely adopted in biomaterials, dental composites, coatings, sealants, and specialty adhesives.
